1. Alfred Wegener used climate to support his hypothesis because he found fossils from tropical climates in nontropical areas.

2. If a fossil of a sea creature is found in the middle of an area that piece of land could've been underwater.

3. Fossils show where or how t he continents were place a long time ago. If sea creature fossils are found on land we would know that the area was once under water.

4. When plant fossils are found in the same place it means they have similar climates.

5.If the lands were connected animals can travel from one area to another. If they died in the other area there fossils would be found there/

1. Alfred Wegener's hypothesis was that all the continents were joined together at some time in the past. He used continental drift to explain evidence of glaciers in tropical areas and plants found on the island of Spitsbergen.
2. Rock cluse were used to support the hypothesis of continental drift because you might observe the similarity rocks from different continents. By this operation, you'll figure out the matching similar property rocks.
3. Fossils helped to support the hypothesis of continental drift by a retile Mesosaurus in South America and Africa. Wegener hypothesized that Mesosaurus lived in both continents long time ago. The fossil of Mesosaurus was found on land areas separated by a large ocean of salt water. Also, another fossil, Glassopteris, which is a fossil plant, supported Wegener's idea. This fossil plant was found in lots of places: Africa, Australia, India, South America, and Antarctica.
4. You would see similar rocks and rock structures on two landmasses that were connected at one time because the rocks that were made had the same property. Which means that it lived in the same adaption of the weather or temperature. However, now it's separated. On each continent.
5. Fossils of the same animal have been found on different continents because animals move. This tells that there's an evidence that the same type of animal was everywhere. Then, the evidence of the land starts to be separated. Then, there's a fossil with the same type of animal on each continents.

1. Wegener found that the fossils of warm-weather plants were found in colder climates. He hypothesized that Spitsbergeb drifted from tropical climates to the arctic.
2. The rock structures on different continents are similar, like America and West Africa. This supports the idea that they were once connected.
3.Fossils of the swimming reptile mesosaurus have been found in South America and Africa. The only way that this animal could have crossed a large salt water ocean is if they were attached.
4.The continents might have separted in the middle of a rocky area, leaveing pieces of it on both sides.
5.Animals that were able to cross areas like these might have brought over the bones, or meat of others. (?)

1) Alfred Wegener used continental drift to explain evidence of changing climates. For example, fossils of warm weather plants were found on the island of Spitsbergen in the Arctic Ocean. To explain this, Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic. Wegener also used continental drift explain evidence of glaciers found in temperate and tropical areas. Glacial deposits and rock surfaces scoured and polished by glaciers are found in South America, Africa, India, and Australia. This shows that parts of these continents were covered with glaciers in the past. Wegener thought that these continents were connected and partly covered with ice near Earth’s South Pole long ago.

2) Rock clues were used to support the hypothesis of continental drift because if the continents were connected at one time, then rocks that make up the continents should be the same in locations where they were joined. Similar rock structures are found on different continents. Rock clues like these support the idea that the continents were connected in the past.


3) Fossils helped to support the hypothesis of continental drift because fossils of the reptile Mesosaurus have been found in South America and Africa. Wegener hypothesized that this reptile lived on both continents when they were joined.

4) I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because animals could have carried those rocks from one place to another. They also could have moved by weathering.



5) Fossils of the same animal have been found on different continents maybe because the climates were similar and could have adapted to that area. Strong winds could have also blew the fossils of the animals to different continents.

1. Alfred Wegener used continental drift to support his hypothesis of changing climates. Fossils of warm weather plants were found on Spitsbergen in the Arctic Ocean. Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic. He also used the continental drift to support evidence of the glaciers found in tropical areas.
2. Rock clues were used to support the hypothesis of continental drift because when rocks that make up the continents are in the same locations where they were joined. Rocks with similarities are found on different continents. The rock clues support the idea of the continents used to be somehow connected.
3. Fossils helped to support the hypothesis of continental drift because animal fossil were found in completely different regions but they were the same type of fossils. So fossils help support the hypothesis of the lands used to be connected.
4. You should expect to see similar rocks and structures on two landmasses that were connected at one time because the rocks that make up the continents should be the same in locations where they were joined.
5. Another explanation for the same animals that have been found on different continents is that animals could have adapted to another region that had the same type of climate that they are used to. They could also have swam to a new location, just like the glossopteris who only swam in fresh water but still was able to end up in different regions.

1. For example, there were fossils of warm-weather plants found in the arctic region. There is no way to explain this except for the fact that the continents used to be connected and the land with the warm-weather plant drifted off to the arctic regions.

2. If Pangaea actually existed, then wherever the continents connected, they would have had similar rocks. Scientists discovered that different continents contained similar rock structures.

3. Fossils helped support the hypothesis of continental drift because for example, there is a prehistoric reptile called Mesosaurus. The mesosaurus could only live through fresh water and fossils of the mesosaurus have ben found in south america and africa. The only way the mesosaurus' fossils could've been found in both africa and south america is if the Pangaea existed and there were several mesosauruses living in the same region.

4. You would expect to see similar rocks and rock structures in two landmasses that were connected at one time because at that one time, the two landmasses were united. They would have the same number of layers and gravity and so the rocks would be shaped and formed the same. If they separate, the rocks would still stay similar.

5. Fossils of the same animal could be found in different continents because the two continents could have been suitable for that type of species. For example: common butterflies can be found in Korea and even in America even though they are different countries. It is always possible.

1) Alfred Wegener used climate clues to support his hypothesis of continental drift because he hypothesized that Spitsbergen drifted from tropical regions to the arctic. He also discovered the evidence of glaciers found in warm areas. This proves that warmer continents were covered with glaciers in the past.

2) Rock clues contributed to support the hypothesis of continental drift because if you were to study the rocks from South America and western Africa, you would discover other rock structures that are alike. So if continents were once connected, rocks that made up the continents should be the same in the same location. These supported the idea that continents were once connected.

3) Fossils helped support the idea of continental drift because fossils of the reptile Mesosaurus have been found in South America and Africa. This reptile lived on both freshwater and on land. Wegener believed that this reptile lived on both continents when they were joined because it couldn't have had swam between the continents.

4) You would expect to see similar rocks and rock structures on two land masses that were once connected because they could've been formed through the exact same processes.

5) Fossils of the same animal have been found on different continents because the reptiles may have been indigenous to a certain country or area. The fossils and remains of the animal may have been carried away to different regions as well.

1.Wegener stated that continients were once conected and slowly moved to their location now.
2.Wegener also said thatthe Mesosarausus couldn't swim between contineints therefore the land must have been conected at one point.
3.Some fossils were discovered in places where they couldn't have survived unless the contineints were connected.
(like the example above)
4.i woould expect to see this because since the continients were atached the rock formation were most likely realitivly close therefore under the same weather conditions.
5.maybe the animal lived on the borber line of the pplates do when they seperated and became continients the animals moved with it.

1.He showed that glaciers covered some locations in the tropics, he explained that these continents in which the glaciers were located might've been connected and partially covered with ice near the Earth's south pole.
2.Similar Rock formation were found in different continents, parts of the Appalachian mountains in the US were are similar to parts found in western Europe and Greenland.
3.a samee type of plant fossil was found in different continents, this shows that one time, these continents were one and shared similar climates.
4.becasue since before the continent was probably connected and so that's the reason why there is similar rocks formations and structures.

1. Wegner used the climate clues to support his hypothesis by using the examples he came up with. For example, when he used continental drift to explain the evidence of glaciers found in temperature and tropical areas. It was said that some glacial deposits and rock surfaces were scoured by glaciers which were found in South America, Africa, India, and Australia. Those continents are mainly continents with climates not suitable for glaciers, but according to Wegner’s theory those continents were connected somewhere covered in ice near the Earth’s South Pole. He also so used the example of the fossil of the warm weather plant which was found on the island of Spitsbergen, in the Arctic Ocean.
2. Rock clues were used to support the continental drift by the explanations of the location of particular rocks. For example, parts of the Appalachian Mountains located on the eastern United States were similar to the ones found in Greenland and western Europe. This explains that similar geographical features (rocks, mountains) occurred next to each other when the continents were joined up before.
3. Different fossils helped support the hypothesis of the continental drift.The fossils of the reptile Mesosaurus have been found South America and in a near by continent, Africa. The fossils of warm weather plants also helped support the hypothesis.
4. I think you would see similar rocks and rock structures because if the landmasses were connected to each other, they would have had similar climates. It is also likely because it is likely to have many rock structures or mountains rather than just one standing by itself.
5. Same animals could be found on different continents because they may have been once attached. If the seven continents today have been connected a long time ago, I think it is possible for animals to have lived on one land mass. And as time went by, I think that the continents started moving apart, which caused the animals to move as well as the land itself.

1)Fossils of warm wather plants were found on the island of Spitsbergen in the Artic Ocean. This meant that Spitsbergen was once in a hot and tropical region. But now is in the Artic Ocean.

2)IF the continents were connected at one time then rocks that make up the continents should be the same in locations where they were joined. Similar rock structures are found on different continents. This means that they were once connected because, the rocks that were found in the two continents were the same.

3)Fossils help support the hypothesis of continental drift because, the reptile Mesosaurus's fossils were found in South America and Africa, this means that the two continents were once connected.

4)Because, rocks make up land and if they were connected then the rocks that made up their land would be the same.

5)The fossils of different animals were found in different continents because, we believe that the continents were once combined. So the animal fossils that are found in South America is also in Africa it means that they were once connected because the animals living there were the same

1) Wegener used climate clues to support his hypothesis. His hypothesis was that at one point in time the contents were very close together. One of the things that someone found to prove his statement true was that people found fossils of warm weather plants on an island in the Atlantic Ocean. Wegener explained that the island was in a tropical area and over time floated into the arctic. Another example is glacier deposits are found in places like India, Africa and Australia where it is really hot today. This shows that in the past these places must have been covered in glaciers. They were connected somewhere cold.
2) Rocks also prove Wegener’s theory right. Pieces of rocks found in South America and pieces of rocks found in Western Africa have very similar structures. The only explanation for this is that the land masses had to together, or very close. Why else would similar rock structures form on different land masses that are very far away from each other?
3) Fossils from animals have been found on two or more continents. These animals could not have swum across the Atlantic or Pacific Ocean. An example of this is the reptile Mesosaurus. Fossils from this type of reptile were found in South America and Africa. The Mesosaurus lived on land and in fresh water. It could not have possibly swum that far in salt water. It also would make no sense for it to swim that far even in fresh water. Wegener was sure that the reptile swam to both pieces of land.
4) You would expect to see similar rocks on land masses that were once connected because the land masses were connected by rocks. When the two land masses split the rocks split with the land masses.
5) An alternative explanation for why the fossils of animals have been found on different continents is they ran out of resources on one continent and had to migrate to another to survive.

1. Wegener used climate clues to support his hypothesis of continental drift by saying that the Island of Spitsbergen which is in the Arctic Ocean had warm weather plant fossils. Also, Some countries that do not have glaciers now have glacial deposits which means there were at one point glaciers.
2. Rock clues were used to support the hypothesis of continental drift because there were similar rock structures found where the continents were believed to be connected.
3. Fossil clues were used to support the hypothesis of continental drift by saying that fossils of the Mesosaurus were found in south America and Africa. Since these dinosaurs lived on land and freshwater, it would be impossible for them to cross a large ocean of saltwater. Therefore, they could have lived on both continents when they were connected together.
4. You would expect to see similar rocks and rock structures on two landmasses that were connected at one time because since the land was connected, the rock would form in one area.
5. An alternative explanation for why fossils of the same animal have been found on different continents is that they could have migrated by traveling from Alaska into Russia.

1. Alfred Wegener explained the continental drift by using climate clues that fossils from warmweather plants were found on the islands of Arctic ocean today. Which means that Spitsbergen drifted from tropical regions to arctic.

2. Similar types of rock were found in different regions such as, America and Europe, which means that continental drift had happen long time ago.

3. The reptile Mesosaurus have been found in two different continents across the ocean. However, they could not swim across the salt water so we believe that continental drift moved those fossils.

4.Since the two landmasses were connected at one time, they probably had same types of rocks and rock structures at that time. When they were seperated by the continental drift, still kept their rocks and structures which led us to see similar types of rocks on two landmasses today.

5. Because those two continents once joined together and had various types of species. However, since they went through the continental drift, animals seperated and today, we could find fossils of the same animal on different continents.

1) Wegener used climate clues to support his hypothesis of continental drift by showing signs of climate change. He noticed that fossils of warm weather plants were found on an island in the Arctic Ocean. His explanation for this was that the island had DRIFTED from the tropical regions to the arctic. He also used the fact that there are signs of glaciers in temperate/tropical areas, and, using evidence, he showed that the continents were once connected and partly covered with ice near the South Pole.

2) Similar rock structures were found on different continents, which supported the idea that continents used to be connected in the past. For example, parts of the Appalachian Mountains of the Eastern United States were similar to those in Greenland and western Europe.

3) Fossils helped support the hypothesis of continental drift because fossils of the prehistoric reptile Mesosaurus were found in both South America and Africa. This meant that the Mesosaurus probably lived on both continents when they were joined. Basically, fossils of the same species have been found in different continents.

4) It would be expected to see similar rocks and rock structures on two landmasses that were connected at one time because rocks make up the continents/ landmasses, and rocks formed in the same location should be the same or similar.

5) An alternative explanation for why fossils of the same animal have been found on different continents is that it may not have been the continents that drifted, but that it may be the climate which has changed over the course of time (example: ice age,) thus affecting the conditions of life for organisms in each continent.

1. Wegener used cilmate clues to support his hypothesis by showing that there were evidence of tropical weather plants found in cold places which meant that the cold places were once in a tropical climate. He also showed it by looking at the evidence of glaciers in tropical or hot places.

2. Rock clues were used to support continental drift by seeing the rock structures being similar to other rock structures in other continents.

3.Fossils helped support the hypothesis of the continental drift by having the fossils of one type of dead animal on a different continent. THere is also fossils like the tropical plant that shows that it was in a tropical place.

4. You would see the same rock structure on two different landmasses because they used to be connected so the rock structure formed on both of them because they were combined, then they drifted apart. The rock structures stayed on them when they drifted apart. That is probably why you would see the same rock structures on different continents.

5. Fossils of the same animals are found on different continents because they either migrated there, or when the continents were together, they lived on both of them.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift because scientists have found fossils of warm weather plants in areas of the Arctic Ocean. He also used the evidence that there are glacier deposits in areas where there are no glaciers today.

2. Rock clues were used to support the hypothesis of continental drift because similar rock structures have been found on different continents. Parts of the Appalachian Mountains of eastern U.S. greatly resemble mountains found in Greenland and western Europe.

3. Fossils helped support the hypothesis of continental drift because fossils of the same animal have been found in different places. For example, fossils of Mesosaurus have been found on both Africa and South America. It is impossible for this swimming reptile to have swam across a large ocean of salt water. Therefore, there must have been a time when Africa and South America were connected.

4. I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because the landmass simply split, but left all of the physical features. If there was originally a mountain range, and the continent split on it, the same mountains would be found in two different places.

5. Fossils of the same animal could have been found on different continents because during the ice age, where Alaska and the tip of Russia were connected by a path of ice, animals may have moved from Alaska across that path, and gone to Asia, where they could go to other continents such as Africa.

1. fossils of plants and or animals that are from warm climates have been found in cold places which shows that the continents have probably moved over time
2. different parts of the same rocks have been found on different continents which show that when the continents had to be together at some point.
3. fossils have been found split up on different continents
4. the continents used to be all together but when they split half the belongings would go one way and the others would go another way.
5. o lot of animals look alike so sometimes people might confuse different fossils as the same on

1. Alfred Wegener found out that the weather climates of the areas overlapped. He used this information and others to conclude that continental drift did occur.
2. Scientists found an overlap of rocks of the areas that were once connected and the edges have the same rocks. So from that, we can find out that the two areas were once right next to each other.
3. Fossils further proved the hypothesis of continental drift. The animals engraved in the fossils were similar and some the same as other animals in another area far away.
4. Similar rocks and rock structures would be expected to see on the two landmasses that were connected at one time because both landmasses underwent the same type of weather and erosion. Many things that happended to the areas affected both regions a long time ago.
5. Different fossils of the same animal cold be found on another continent if the areas have similar conditions. Animals adapt accordingly and thus can be really similar.

Q1: Because fossils of warmweather plants were found on the island of Spitsbergen in the Arctic Ocean which are cold, he could prove that once they were connected.

Q2: Rock clues supported his hypothesis because, similar rock structures were found on different continents at their borders.

Q3: Fossils help to support his thoughts because fossils of the same organism was found in different continents.

Q4: Because rocks were at the two borders that been seperated and went to two different continents.

Q5: Because once when those two continents were connected the kind of animal was living right on the spot where the continent got seperated. And as it split some of the organisms got seperated.

1) Alfred Wegner used climate clues to support his hypothesis of continental drift by using fossils of plants or glaciers. For instance, fossil of plants that grew in warm weather were found of the island of Spitsbergen in the Arctic Ocean. To explain the situation, Wegner hypothesized that the island of Spitsbergen drifted from the tropical regions to the arctic areas. Also, he explained the fact that glaciers were found in tropical areas using continental drift.
2) Rock clues support the idea that continents were connected in the past because similar rock structures are found on different continents. For example, parts of the Appalachian Mountains of eastern United States are alike to the ones found in Greenland and western Europe.
3) Fossils clues supported the idea that the continents were together in the past because fossils of the reptile Mesosaurus were found in both South America and Africa. Mesosaurus could survive on land and in water. However, it was unlikely that this swimming reptile could swim between the continents, therefore Wegner hypothesized that Mesosaurus lives in both continents when they were attached.
4) I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because the rocks made up the two landmasses, therefore they should be similar.
5) Fossils of the same animal were found on different continents because when the continents were attached, they had similar climates, and so species ive in the same are. However, when the continents became seperated, the fossils of the the species were sepreated as well.

1.Wegener used climate clues to support his theory of continental drift by comparing animals or plant species that were to have said to live in a certain climate. He found that these animals were found all over the world in various continents. Since they were the same species, however, these areas had to have similar climates at a certain time and they only way this could be true is if they were connected.
2.Rock clues were used to support the hypothesis of continental drift by comparing the rocks where the pieces of the Earth were supposed to be connected. Scientists were able to find that areas such as the Appalachian Mountains in the United States were indeed similar to those found in Western Europe and Greenland.
3.Fossils help support the hypothesis of continental drift because by comparing the animal fossils in certain regions you can predict that they were once similar climates and therefore probably were connected together in the past.
4.You would expect to see similar rocks and rock structures in an area that was once connected because since rocks take thousands of years to form one would think that the rocks in this area were formed around the time of Pangaea and are similar.
5.I can infer that since the beginning of Earth’s existence this place had the same exact climate and temperature. Since the smallest of organisms were the ones to first exist in Earth, these bacteria evolved similarly, creating similar organisms. If this didn’t occur it can be possible that the fossils are not the same. The same organism that made the fossil evolved and someone got moved to different areas of the globe. These very different organisms then continued to survive on this completely different continent. When comparing just the fossils, which are just the bone structure, however, it can look very much the same.

Alfred Wegener used climate clues to support his hypothesis of continental drift by explaining how fossils of warm weather plants on the island of Spitsbergen drifted from tropical regions to the arctic. He used continental drift to explain the evidence of glaciers found in temperate and tropical areas. The glacial deposits and rock surfaces scoured and polished by glaciers that are found in South America, Africa, India, and Australia prove how the continents were one large land mass.
2. Rock clues were used to support the hypothesis of continental drift by where the rocks were located. For example, some rock structures are found on different continents which prove that the continents were connected at one time. Parts of the Appalachian Mountains of the eastern United States are similar to those found in Greenland and Western Europe. Also, the rocks from eastern South America and western Africa are similar.
3. Fossils helped support the hypothesis of continental drift by many ways. For example, Glossopteris, a fossil plant, was found in Africa, Australia, India, South America, and Antarctica. The presence of this plant in so many different areas supports the idea that all of these regions were connected long time ago. Also, the fossils of Mesosaura, a reptile, have been found in South America and Africa. This also proves that the continents were once joined together.
4. I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because if the continents were once a large land mass, then the rocks that make up the continents should be the same in locations where they joined.
5. Fossils of the same animal have been found in different continents because the same species moved to different areas and then the large land mass divided into continents.

1.Alfred Wegener used climate clues to support his hypothesis of continental drift by comparing present day climates and ancient remains. For example, there are glacial remains in South America and Africa, two very warm climates; this must mean that long ago, these continents were closer to the South Pole where the climate could have been cold enough to form glaciers.
2.Rock clues also helped to support Alfred Wegener’s idea of continental drift. For example, one type of rock that is found in North America is also found in Greenland, not only that but the two rocks are in the positions they should be if the continents were attached.
3.Fossils are yet another clue that supported Alfred’s idea. Fossils of the Mesosaurus were found in South America and also in Africa. These creatures live on land and in freshwater and it would be impossible for them to have swum from one continent to the other; this means that the two continents must have been attached.
4.You might expect to see similar rocks and rock structures on two different continents that may have been connected at one time because, at one time they would have shared similar characteristics due to being located in the same area, also when they split apart, the rock futures would in turn be split apart and separate.
5.It could be possible for certain creatures like the Mesosaurus to have existed on two separate continents. This does not mean that they would have had to swim from one continent to the other; it could be possible that they did not start out on one certain continent but in fact already existed on both continents. Also, perhaps human beings or other animals brought the creatures over to the other continent.

1. Alfred Wegener used climate clues from two areas to support his hypthesis of continental drift. The climate from two different continents were similar thus he used that to support his hypothesis.
2. Rocks that were similar in two different areas and how overlapping characteristics such as the weather were also used to support his hypothesis.
3. Fossils that were similar and had similar animal shapes were also used to suppor the hypothesis of continental drift. The animals were very similar which was used to support the hypothesis.
4. Similar rocks and rock structures could be similar if they were connected at one time becuase the conditions of that area was the same.
5. Similar fossils can be found on different areas even when they weren't connected a long time ago if they had similar conditions and weather.

1.Alfred Wegener used climate clues to support his hypothesis of continental drift by saying that there were continenets that were filled with glaciers in the past which is now South America, Africa, India and Australia.

2.Rock clues were used to support the hypothesis of continental drift was said that there was a rock that was joined. However one part is in a different location than the other piece. When they are joined it fits together.

3.Fossils helped to support the hypothesis of continental drift by a fossil called Glossopteris. This fossil has been in Africa, Australia, India, South America, and Antarctica. Wegener thinks that these locations should have been connected and had similar climates.

4.I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because long ago they were once connected and the rocks might would have been produced, however as time past by, the lands could have seperated. So even though the location is far apart the same types of rocks would be spread out to different areas in the world.

5.Fossils of the same animal have been found on different continents, it might be that the animals moved their homes to another location in the world.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift. The reason is because two fossil plants were found in two different countries, which means those countries once had a same climate.

2. Rock clues were used to support the hypothesis of continental drift. The rocks that make up the continents in the same location where they were joined were connected. Also they have similar rock shapes.

3. Fossils helped to support the hypothesis of continental drift. A reptile fossil for example, it is found in Africa and South America, which means these countries were connected.

4. You expect to see similar rocks and rock structures on two landmasses that were connected at one time, because they had same features and climates to change the rock.

5. Fossils of the same animal have been found on different continents because they lived in those countries when the countries were connected.

1. Wegner used climate clues to support his hypothesis of continental drift by illustrating the fact that there were warm weather plants in cold places like the arctic.

2. Various landforms from different places of the world sometimes have many similar defining characteristics, suggesting that those landforms were once next to each other.

3. There are many fossils that are located in certain places that force us to deduce that there WAS once a pangea. One example is when a plant is found in one place in the world, and is found in another place as well.

4. Because most likely those landforms formed in the same way, and resemble each other after Pangea split.

5. There is always the possibility that a flying animal carried a pair of a certain species, causing them to spread throughout two lands.

1. Explain how Alfred Wegener used climate clues to support his hypothesis of continental drift.

Alfred Wegener used climate clues to support his hypothesis of the continental drift by saying that the reason for glaciers found in tropical areas, and finding glacial deposits in south America, Africa, India, and Australia. It is strange to find ice deposits in places that do not have ice now.

2. Describe how rock clues were used to support the hypothesis of continental drift.

Rock clues were used to support the hypothesis of the continental drift, by finding the same type of rocks in different locations of the earth. For example the rocks in the Appalachian mountain of eastern United States is similar to the one located in Green land and western Europe.

3. Summarize the ways that fossils helped to support the hypothesis of continental drift.

Fossils helped to support the hypothesis of continental drift because Fossils of the same reptiles could be found in several different locations. The reptile called Mesosaurus could not swim between continents so he concluded that the reptile lived in different continents when all the lands were joined together.


4. Why would you expect to see similar rocks and rock structures on two landmasses that were connected at one time?

You would except to see similar rocks and rock structures on two land masses that were connected at one time because the land would have been connected. If there is a mountain that is between the two continents that were cut, the rocks in the mountain will be very similar, because the same mountain was cut in half. This can cause the similarities of rocks to occur in different places.

5. Give an alternative explanation for why fossils of the same animal have been found on different continents. (This answer is not in your textbook).

An alternative explanation for why fossil of the same animal have been found on different continents is that the animals might move to different locations every time they breed. They could also have been migrating to different places each year.

Answer
1. Alfred Wegener used climate changes by looking at fossils. He found a warm weather plant fossil in an island in the arctic and glacial deposits and rock surfaces scoured and polished by glaciers were found in South A., Africa, India, and Australia.

2. Rock clues were used by finding similar rock structures in different continents. FOre example, parts of the Appalachian Mountains were similar to mountains in Greenland.

3. First people have found fossils of the same organism in different continents. Also, they found a fossil of a reptile that lived on land and survived in FRESH water in an ocean.

4. This is because scientificly there is a belif that the land was one continent called Pangaea. That is why all our continents kind of match up like a puzzle. Since they were all matched up before, there would be rocks that are similar in one area. But now that lands have been split up, it wouldn't look like that.

5. It is possible that for animals, if they are able to fly, they could have flown over and had more babies. Another possible cause is that plant seeds were blown over the ocean by winds and landed up in other continents.

1. Wegener used continental drifts for the changes in climates. THis is because he found fossils that were plants that came from warm places. He also hypothesized that there used to be glaciers, but because of the continental drift, it melted.
2. Rocks were used as a support for the continental drift because similiar rocks were found in different continents. So, he though that the ands were one all together.
3. Fossils helped support the continetal drifts because there were used to be the same animals the lived in the same land, but because of the continetal drift it might of have seperated.
4. You would see similar rocks amd rock structures on two different landmasses because the continents were once together and because of the plates, it moved and got seperated.
5. You can find the same fossils on different continents because the land moved, and also there might be the same species living on different lands.

1.)Alfred Wegener used climate clues to support his hypothesis of continental drift by saying that glacier deposits are found in continents where no glaciers exist because some of those continents were connected by ice frozen over that had also been connected to the south pole.
2.)Rock clues were sued to support the hypothesis of continental drift because if the continents had been all connected once, the rocks would've been connected too, and this is shown when many continents have similar mountains and rock formations on their coasts.
3.)Fossils helped support the hypothesis of continental drift because fossils of certain dinosaurs are found on coasts of different continents that, if connected, would show certain areas where certain dinosaur's had lived.
4.)You would see similar rocks and rock structures on two landmasses that were connected at one time because the rocks would have been one rock that then split in half and stayed on the continents as they separated.

1. Wegener used continental drift to explain evidence of changing climates. For example, fossils of warm-weather plants were found on the island of Spitsbergen in the Arctic Ocean. To explain this, Wegener hypothesized that Spitsbergen drifted from tropical regions to the arctic. Wegener also used continental drift to explain evidence of glaciers found in temperate and tropical areas.
2. Parts of the Appalachian Mountains of the eastern United States are similar to those found in Greenland and western Europe. Rock clues like these support the idea that the continents were connected in the past.
3. Fossils of extinct animals have been found in different continents. That shows that the animal used to live on both continents when they were joined together.
4. You would expect to see similar rocks and rock structures on two landmasses that were connected at one time because it used to be just one piece of land with the same rock structures.
5. Fossils of the same animal have been found on different continents because weathering and erosion have moved the animals' decayed bones to other pieces of land.

1. Alfred Wegener had a hypothesis that 200 million years ago the continents were all joined together. To support his hypothesis he used climate clues. A supoprt he had was that there were glaciers located in South America, Africa, India, and Australia. But today, in the present there are no glaciers in those areas at all. So Wegener thought that these continents were connected near the earth's south pole. Alfred Wegener also found fossils of warm weather plants on Spitsbergen in the Artic Ocean. To explain this he said that the island of Spitsbergen drifted from the tropic regions to the artic.

2. Wegener also used rock clues to support his hypothesis. Wegener found many types of similar rocks structures on different continents. So Wegener said that rocks that make up continents should be the same in locations. He also figured out that parts of the Appalachian Mountains in the U.S.A. are also similar to parts in Greenland and western Europe. Also, many rocks from Africa and South America also have similar structures.

3. Fossils help support the continental drift because scientists have found fossils of reptiles and plants on different continents for example the mesosaurus has been found in South America and Africa. Since this reptile lived on both land and freshwater. How could the fossils of this reptile be seperated by a giant ocean filled with salt water? SO we believe that they lived on both continents when they were connected.

4. You would expect the see similar rocks and rock structures on two landmasses that were connected because it makes sense. Today people believe that the continents were all connected, so people try to find the relationships between the continents to prove the theory correct or incorrect. Also, the more information and similarites one finds in the two continents that were connected it helps people understand the concept more.

5. Fossils are usually found on different continents because they used to all be connected. Another reason that fossils of the same animal have been found on different continents because the fossils of animals and plants could have drifted from place by the ocean (water) or by the animals. Also when the lithospheric plates are pushed by magma, the fossils could be moved. Also if there was a giant storm the animals could have been drifted away to a new area and fossilized there.

1.Alfred Wegener used climate clues to support his hypothesis of continental drift by pointing out things like how fossils of warm-weather plants were found on an island in the Arctic Ocean. This was a clue that the island drifted into the arctic from tropical regions.
2. The fact that similar rock structures are found on different continents suggest they were connected. If continents used to be connected, then rocks that make them up should be the same in locations where they were joined.
3. Fossils help support the hypothesis because some fossils like the Glossopteris plant has been found in Africa, Australia, India, South America, and Antarctica. Fossils help support the hypothesis because some fossils are found in places they shouldn't be in today because of weather differences.
4. I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because if they were connected then the places where they were joined should be the same.
5. Another explanation is that the climate was all different and maybe the fossils could have lived where they were found.

He used climate clues to support his hypothesis because he said that there were warm weather plant fossils found in places were it is exetremely cold now. He said that the continental drift was the reason. He also said that places with with rock surfaces that were changed due to glaciers were another example. Because now the places are in tropical area's were there are no glaciers, which supported his idea that there was a continental drift.
2. They were used because he said that if you studied the rocks found for example from eastern south america and western Africa there were rock structures that were similar. This was because they used to connected.
3. They helped because they found fossils of the same dinosaurs in different continents that were far away, but were said to be connected before the continental drift. There were also plant fossils that helped support his hypothesis. They helped because warm weather plant fossils were found in places that are too cold for them to have grown in today.
4. Because the rocks should be the same at places were the continents were joined.
5. Maybe they are found on different continents because both continents had very similar climates so the animal lived on both continents.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift by questioning why tropical plant fossils were found in colder regions and why there were traces of glaciers in warm areas. He reasoned that these areas were once in different places and the continental drift had separated them from their respective climate conditions.
2. Rock clues were used to support the hypothesis of continental drift by comparing the rock structure in different continents. Many of the rocks in different continents had similar rock structures, supporting the idea that these land masses were once joined together.
3. Fossils helped to support the idea of continental drift because fossils of the same species of organisms were often widely scattered throughout the world. This would be impossible unless the continents had actually been one land mass and had drifted apart.
4. You would expect to see similar rocks and rock structures on two landmasses that were connected at one time, because the rocks would have formed under the same conditions.
5. An alternate explanation for why fossils of the same animals have been found on different continents could be that some of these animals had migrated from one continent to another. This could be possible if they had mutated in order to cross the sea or if part of the oceans had frozed over for a short period of time.

1.Explain how Alfred Wegener used climate clues to support his hypothesis of continental drift.

Alfred Wegener said that continents have moved slowly to their current locations. Alfred Wegener suggested that all continents once were connected as one large landmass but that broke apart about 200 million years ago.

2. Describe how rock clues were used to support the hypothesis of continental drift.

If the continents were connected at one time, then rocks that make up the continents should be the same in locations where they were joined. This gives you some idea that the continents were connected in the past.

3. Summarize the ways that fossils helped to support the hypothesis of continental drift.

It is because fossil remains of plants and animals that lived in Pangaea have been found more than one continent.

4. Why would you expect to see similar rocks and rock structures on two landmasses that were connected at one time?

If the rocks and rock structures on two landmasses that were connected at one time, then the rocks that make up the continents should be the same in locations where they were joined.

I believe it is because in the past, the earthquake happens and the continents will all mixed together and moved.

Chapter 4 Section 1 Assessment
1. Alfred Wegener used climate to support his theory about the continental drift. For example, he observed that the fossils of warm-weather plants were found on an island, Spitsbergen, which is located in the Artic Ocean. Wegener concluded that Spitsbergen had originally been located on a tropical part of earth’s surface; however, it drifted away to the Artic Ocean when the continental drift occurred.
2. To prove that the continents were previously one, the type of rocks that the continents are made up of should be quite similar. The rocks that once joined all these continents share similar traits which helps prove the fact that all the continents were once connected.
3. Fossils play a very important role when it comes to proving that the continental drift actually took place. For example, the fossil of the reptile Mesosaurus helps prove that the continental drift happened. The Mesosaurus fossils were found on two continents which are South America and Africa. However, present day, these two continents are separated by a large ocean. It would be impossible for the Mesosaurus to swim across the continents and back and forth. Therefore, a practical answer would be that South America and Africa were originally connected; which is why the Mesosaurus fossils are found on both of these distant continents.
4. You would most likely find similar rock structures of two landmasses that were once connected. This is because if two landmasses were originally connected, they wouldn’t be different rock structures because they would have developed under the same conditions as the landmass that it was connected to.
5. Fossils of the same animal have been found on different continents. One reasoning to this unsolved mystery could be because of the continental drift. However, another explanation may be that the animal could have evolved to form the same animal as on the other continent. This could have happen because of the conditions both of the animals were exposed to.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift by fossils of warm weather plants were found on Spitsbegen in the Artic Ocean, so he proved that the islands had drifed from tropical regions to the Artic Ocean.
2. Rock clues were used to support the hypothesis of continental drift by finding similar rock structures on different continenets, this proved that they were once connected.
3. Fossils helped to support the hypothesis of continenetal drift by haveing the same species fossils on more than one continenet, thus proving they were once joined.
4. I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because they were once connected so they once contained all the same species andd landforms.
5. Another explantation for why fossils of the same animal have been found on different continents because the fossils might have been carried by the ocean to different parts of the world. So, that might be why there are fossils of the same species on different continents.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift. He found fossils of plants that live in warm weather in Spitsbergen, the island in Arctic Ocean. He said that Spitsbergen drifted from tropical regions to the arctic.
2. Wegener thought that if the continents were once connected together, there should be similar rocks all around the world. Just as he thought, there are similar rocks on different continents and this shows that they were once connected together.
3. Fossils of Mesosaurus were found all around the world. Mesosaurus swim in freshwarer or live on land. If the continents weren't connected at one point, then it is not possible for the fossil of this animal to be found all around the world. This shows that they were once connected together.
4. I would expect to see similar rocks on two landmasses that were connectd at one thim because if they were connected the wind would carry them to a different place.
5. It is possible that the continent was never connected together even though fossils of the same animal have been found on different continents. There is a possibility that a flying animal took an egg of some animals to a different continent.

1. Some pieces of data that support his hypothesis were,
-South America and Africa fit together perfectly.
-Fossils of dinosaurs were found in similar areas.
-Rock structures matched up.
-Ferns were found in the artic, this was a climate clue.

2. Rock clues were used to support the hypothesis of the continental drift because many mountain ranges seemed to match up.

3. Fossils helped to support the hypothesis of continental drift because many fossils of the same type of organisms were located in the same places.

4. You would be able to expect this because the climates and conditions were all the same when they were connected at one time. Also land masses could have been formed but were split later on when the continental drift occured.

5. Fossils gave clues about continental drift because the living fossils could have been living in one region of land but during the drift they were seperated and were now on different parts of the world.

1.Alfred Wegener used climate clues to support his hypothesis of continental drift by explaining the warm-weather plants found on the island of Spitsbergen in the Arctic Ocean, and the glaciers found in temperate and tropical areas through continental drift.

2. Rock clues were used to support the hypothesis of continental drift by using the fact that many rocks from different places are very similar. For example similar rock structures are found on the Appalachian Mountains of the eastern U.S. as in Greenland and Western Europe. These similarities were explained through continental drift.

3. The ways that fossils helped to support the hypothesis of continental drift are the following:
A) The fossils are used to compare animals in various different places.
B) Plant fossils can be used to determine similar and different plants in various different places.

4. I would expect to see similar rocks and rocks structures on two landmasses that were connected at one time because the landmass location would be relatively close. The location would have similar climates, pressures, and similar things going on under the earth. Causing rocks and rock structures to be the same. These same rocks would be moved through continental drift.

5. An alternate explanation of why fossils of the same animal have been found on different continents is that these animals have migrated through human trade, flying, swimming, etc. These animals have learnt to adapt in such environments and have been able to do so without major changes within bone structure.

1.Alfred Wegener used climate clues to support his hypothesis of continual drift by the facts that laciers were at one time on many different tropical continents today and this could explain how all the continents were once connected. Also the fossils of warm weather plants were found in the Arctic Ocean.
2.Rock clues were used to support the hypothesis because some of the rocks on different continents today were found where they would heve been connected.
3.Fossils helped to support the hypothesis of continental drift by finding the same fossils in several different continents and by having tropical plants found in Arctic waters.
4.You would expect to have similar rocks or rock structures on two different continents that were connected at one time because if they were connected then they would have had similar climates, animals, and rocks.
5.Another explanation for why fossils of the same animal have been found on several different continents is because the climates were at one time the same and so the same animal could have been found in 2 different places but have no relation to the other. Just like how black bears are found on several different continents, but these continents have the same general climate.

1. Wegener used climate clues by using the continental drift to explain how some tropical plants were found on an island in the Arctic Ocean. He hypothesized that the island drifted from a tropical region to the Arctic. Also, glacial deposits were found in places like Australia and Africa. These places have no glaciers today. Wegener hypothesized that these continents were all connected and covered with ice a long time ago.
2. Some continents have similar rock structures. This supports that continents were connected in the past. For example eastern South America and western Africa have similar rock structures.
3. Fossils also supported the idea that the continents were all joined long ago. Fossils of a reptile have been found in South America and Africa. The reptile lived in freshwater and on land. It probably couldn't swim between two continents. Wegener hypothesized that the reptile could have lived in both South America and Africa when they were joined.
4. You would expect to see similar rocks and rock structures because they formed while they were connected. When The continents were connected the rock structures would form on it. When they would separate the structures would still be there.
5. Fossils could have gotten there for various reasons. Maybe the creature could fly or swim and it just migrated over to a different continent. It's also possible that a creature died near the ocean and the waves and currents carried it to another continent.

2. Similar rock structures were found on different continents, such as the Appalachians in the US that resemble mountains found in Greenland/Europe.

3. Fossils of the same animal were found on different continents. For example, fossils of Mesosaurus were found on both South America and Africa. Since Mesosaurus couldn't survive in salt water, they must have been in the same area before the land broke apart.

4. Since the same landmasses have similar terrain, they'd be similar even when split.

1) well he used climate clues to prove his point. He found a fossil of a reptile that lives in warm areas in a really cold area so he stated that it must have been in a different spot before.
2)Rock Clues are also used to prove that earth used to be one. Parts of mountains are found in the U.S and in Greenland.
3)Fossil Clues were used because there was a animal that lives in fresh water and in land and was found in South Africa and in Africa and that meant that they were connected because they couldn't swim across the ocean.
4)You would expect to see the same rocks in an area that used to be connected because there would be the same erosion and plant life decaying inside of it.
5)Well you could also find fossils of the same animal in different continents because maybe someone brought one over and bred them.

So, there is possibilites that animals were lived in varity areas on this large landmass, which can prove that same kind of animal fossil can be located in different continents when it seperated.

2. The rock clues supported Wegener’s hypothesis because the rocks that make up the continents were the same kinds of rocks in locations where they were joined.

3. By using fossils of different plants and dinosaurs, Wenger was able to support his hypothesis, because he found fossils of the same dinosaurs in different continents where they couldn’t have gone by swimming. (Same with the plants) pg 99 and 100

4. Many people would expect to see similar rocks and rock structures on two landmasses that were connected at one time because for example, if you cut a chocolate chip cookie into 5 pieces, the shapes and the sizes of the 5 pieces would be different, but after all they would have the same structures. They will have the same type of chocolates in them and the same type of dough.

5. A.) A flying dinosaur could have eaten a dinosaur during its travel in a continent and could have died in different other continent.

B.) A dinosaur could have drowned in a shore of a continent and could have been drifted to a shore of a different continent.

1. Alfred Wegener gave examples on how he used climate clues to support his hypothesis of continental drift. His example was about the warm-weather fossils found on the artic regions. Which explains that the continent was once a big land that gradually got separated into pieces. Another example was about the glaciers found in the tropical areas. This also explains that these areas were once connected to the Earth's south pole.
2. The rock clues were used to support the hypothesis of continental drift by similar rock structures becoming discovered in different parts of the continent.
3. Fossils helped to support the hypothesis of continental drift in many ways. In general, the idea that similar rocks and fossils were found in different parts of the continent supported the hypothesis and explained that the continent was once a big chunk.
4. We can expect to see similar rocks and rock structures on two landmasses that were connectd at one time because the world was once a huge chunk. After the continental shift the rocks will break into two pieces at get separated.
5. Fossils of the same animal gave been found on different continents because of the continental shift. Long ago, the land was a big chunk of land. When a living organism dies it takes time to become a fossil. At the same time, the continental shift happened which made the fossil break into man different pieces. These pieces will have the same structure and will be found on two different continents.

1. Alfred Wegener supported his hypothesis by using climate clues that showed glacial deposits and groove bedrock that were found in South America, Africa, India, and Australia. Also fossils of warm weather plants were found on the island of Spitzbergen in the Arctic
2. Alfred Wegener supported his hypothesis by using rock clues that showed similar rock structures in the Appalachian Mountains, Greenland, Western Europe, South America, and also Western Africa.
3. Fossils helped support Wegener's hypothesis because when they found the same fossils in different places, it showed that the fossils were in the same place and iot split in the middle, transporting the fossils to different parts of the Earth.
4. If when there was Pangea, the rocks were on the border of where the earth split, then the rock structure would have gone onto both sides of the continent when they spread apart and that resulted in similar rocks being on different parts of the Earth.
5. If the landforms were connected back then, then there would probably be the same fossils on both sides because they were nar each other when the fossils were made.

1. Explain how Alfred Wegener used climate clues to support his hypothesis of continental drift.

Wegener said that there were warm weather plants found in the Artic Ocean which proves that they were all once connected. Another piece of evidence is that there were glaciers found in temperate and warm areas.

2. Describe how rock clues were used to support the hypothesis of continental drift.

There were similar rocks found in different continents. This helped proved that the continents were once all conncted together and that the continenetal drift really occured.

3. Summarize the ways that fossils helped to support the hypothesis of continental drift.

Creatures like the Mesosaurus were found in South America and Africa. This reptile lives in freshwater and land which makes it impossible for it to cross over a large salt water ocean. This supports the fact that the continents were once all combined together.

4. Why would you expect to see similar rocks and rock structures on two landmasses that were connected at one time?

It would be because similar rocks form in similar circumstances so if two pieces of land were originally together, they would form similar rock structures because they had similar conditions.

5. Give an alternative explanation for why fossils of the same animal have been found on different continents. (This answer is not in your textbook).

Fossils of animals could have drifted away if it was near the coast to another continent. This could have happened a long time ago and so the fossils would be buried causing some scientists to think that the continents were once all put together.

1) He explains, how two locations that were once connected have the same climate. They are now separated.

2) They found rocks that were on different land pieces, which indicates that these land pieces were once connected.

3) Experts found fossils of sea creatures on land, which illustrates that these land masses used to be under water.

4) They were made out of the same rocks.

5) The continents that had the same animal fossils were once joined together and were separated by lithospheric plate divergence.

1.He used climate clues to support his hypothesis by telling how the continents were driven by the spin of the earth, and how the reptile Mesosaurus has been found in different continents when it cannot swim across the oceans. He also explained how the Glossopteris fossil had been found in different continents so that proves that all of these regions must have been connected and had similar climates.
2. If the continents were all connected at one time, then the rocks that make up the different continents should be in the same places when they were joined. This is shown by how the parts of the Appalachian mountains are similar to those found in Greenland, and you can find rock structures that are similar in South America and western Africa.
3. Some fossils are found in completely different parts of the world, but are made up of things that could only grow or live in certain climates. This proves that these places must have at one point been connected and shared a climate.
4. the rocks that make up the continents should be the same because they were in the same locations when they were joined.
5. Because the animals may have migrated across the oceans or small seas when they were frozen over and many ice bridges were formed

1.Alfred Wegener used climate clues when arguing that there was a continental drift. For example, he said that the fossils of warm weather plants were found on the island of Spitsbergen in the Arctic Ocean. He hypothesized that Spitsbergen drifted to the Arctic Ocean. He also used the evidence of finding glaciers in tropical areas such as South America, Africa, India, and Australia.
2.Rocks were also used to explain the hypothesis of the continental drift. For example, similar rock types have been found on different continents. Parts of the Appalachian Mountains in the eastern United States have been similar to those in Greenland and western Europe.
3.Wegener hypothesized that since there were mesosaurus fossils found in Africa and South America, they must have been transferred to Africa and South America during the drift.
4.Since there were similar rock structures on the same piece of land then during the drift, they could have easily broken in the middle of the structure or off a little part and have some of the same rock on the continent when it formed.
5.The great flood (Noah's Ark) could have a big impact on why fossils of the same animal have been found on different continents because during the flood, there must have been a lot of trees or wood floating around and if some small bugs or animals survived that, they could have easily been relocated. For example, some seashell fossils have been found on mountain tops. Since it's not at all close to the sea, how do you explain that? I believe the flood is a reason of the distribution of animals to different continents.

1. Alfred Wegener used climate clues to support his hypothesis of continental drift by stating that tropical fossils found in cold areas today were once part of the tropics, and vice versa for glaciers in modern warm climates.
2. Rock clues were used to support the hypothesis of continental drift by comparing the similar rock structures of places that had once supposedly been connected.
3. Fossils helped to support the hypothesis of continental drift by the fact that same types of fossils are found in very seperated areas.
4. I would expect to see similar rocks and rock structures on two landmasses that were connected at one time because they were both formed under the same climate, pressure, location, etc.
5. An alternative explanation for why fossils of the same animals have been found on different continents is that a herd of animals might have migrated in search of something that was running out.

1. Wegener used climate clues to support his hypothesis. He did this by showing that a plant that was widespread in so many continents was parted by vast oceans. The theory suggests that the plant could only survive if the regions were all together with similar climates.

2. Rocks were used to support the hypotheses of continental drift through their structures. Continents that are separated now have mountains with similar rock structures such as the Appalachian mountains in the eastern US and the mountains of Greenland and western Europe.

3. Fossils helped support the hypothesis of continental drift because they are the remains of things that could have been during pangaea. Similar fossils were found in different countries that could've been connected before the drift.

4. You would see similar rocks and rock structures on two land masses that were connected at one time because they would have been a huge connected rock that became separated through time.

5. Fossils of the same animal can be found on different continents because they once were on the same connected landmass.

1. He explained it by using climate clues because for example fossils of warm weather plants were found on the island of Spitsbergen in the Arctic Ocean. To explain this Wegener hypothesized that Spitsbergen drifted form tropical regions to the arctic.

2. Similar rock structures are found on different continents. Parts of Appalachian Mountains of the eastern United States are similar to those found in Greenland and western Europe.

3. Fossils of the reptile Mesosaurus have been found in South America and Africa. And because the it probably couldn't swim between the continents Wegener hypothesized that the reptile lived on both continents when they were joined.

4. Because rocks that make up the continents should be the same in locations where they were joined.

5. because they might have been able to swim between long distances.

1. Fossils found in the Arctic were of a warmer climate than today's Arctic climate. Tropical plants were found in the Arctic. Therefore, there had to have been a time when the Arctic lands had a similar climate as other continents where tropical fossils were found.

2. Many continents had similar geological formations and rocks of the same age had the fossils of the same organism in different continents.

3. Fossils of the same species have been found in different continents where climates are completely different. Fossils of identical plants and animals were found on opposite sides of oceans which meant that they had to be connected together long time ago as a super continent.

4. Two landmasses that were connected at one time means that it was one chunk of land, not two. So it is logical that these two will share rocks and similar rock structures. It is like baking a same cake in the same oven. Then, later cutting it up. However, it will still have the same icing and stuff.

5. Some animals were marine animals and could travel across oceans. After the Pangaea broke up and formed different continents, these marine animals traveled to different locations and died. Later, they became fossils.

1. All continents have some proof showing that they have similar glaciers, temperatures, and tropical areas. Also, some plants that can only survive in warm weather were found in cold areas.
2. Similar rocks and rock structures were found on the different continents. Also, some mountains the the U.S. are similar to ones in europe.
3. Same types of fossils were found all over different continents. Different plant fossils also have been found on many different continents as well.
4. Wegener's hypothesis was that all the continents were connected at one time. That means when the two landmasses separated from a whole, the rock structures would have separated.
5. The animals once roamed Pangaea and plants grew all over the huge land. When it separated, it must have took the animals and plants with them.

1. Fossil fuels of warm-weather plants were found on the island of Spitsbergen in the Arctic Ocean. With this discovery, Wegener proposed the theory that Spitsbergen drifted from tropical regions to the arctic. Also, glacial deposits and rock surfaces scoured by glaciers are found in South America, Africa, India, and Australia, which show that parts of these continents were covered with glaciers in the past.

2. Rock clues supported the hypothesis of continental drift with the fact that similar rock structures were found on different continents. An example of this is shown with the relation between the rocks from eastern South America and western Africa. If you were to study rocks from the two countries, you would find rocks from both countries that have similar rock structures.

3. Fossils of reptiles or plants have helped to support the hypothesis of continental drift. For example, fossils of the same species of plants or reptiles have been found in different countries. This shows that the reptile or plant was present on the lands or seas when the different regions were once joined.

4. It would be expected for similar rocks and rock structures to be seen on two landmasses that were once connected because when all the regions were once joined, the climate of the regions were all alike, so reptiles (now represented as fossils) that had adapted to a climate of a region [for example] lived on the same land while the landmasses were once joined.

5. Other than the continental drift, a reason why fossils of the same animal have been found on different continents could be because the animal transformed into an animal that was on a different continent. Animals have go through different stages in life, known as undergoing a metamorphosis for certain animals or insects. Animals that have any sort of relation with different species of their kind may possibly evolve into an animal that is on a different continent.

1. Wegner found that fossils of warm weather plants found near the Arctic Ocean. He used continental drift to explain the evidence of glaciers found in temperate and tropical areas. 1.

2. Similar rock structures were found in different continents. Parts of the Appalachian Mountains were similar to those found in Greenland and western Europe.
3. Fossils of dinosaurs were also discovered in different continents and it did not make sense that the same species could have existed an ocean away.
4. This is because if tow landmasses were connected to one another, there would have been similar rocks at that time and as it goes through the rock formation it would account in similar results in different places.
5. Fossils of the same animal could have also been found on different continents because animals could have migrated to other places and those places could have been farther stretched apart by the continental drift.

1) The hypothesis explains that 2 locations, which were once joined hsve the same climate. They were separated and so not the same as before anymore.

2) Specialists discovered rocks that were on different land masses, which shows that these 2 land masses were joined once.

3) Fossils of sea creatures were found on land, showing that these land masses were under water.

4) The rocks were produced out of the same rocks.

5) The continents that had the same animal fossils were once connected and were teared apart by lithospheric plate divergence.

1. Alfred Wegener hypothesized that the fossils of tropical plants were found on Spitsbergen Island in the Arctic because the island drifted from the tropics toward that area. A fossil plant called Glossopteris was found in many continents, so Wegener thought that they were connected and had similar climates.He also supported his ideas by explaining that the glaciers found in tropical regions were the result of the continents being connected and covered with ice long ago.

2. Wegener found that rocks in the Appalachian Mountains were similar to those in Greenland and Western Europe, and also that the rocks of South America were similar to the ones of Africa. He used these findings to explain that similar rock structures were found in locations where parts of continents were joined.

For example, parts of the Appalachian Mountains of the eastern United states are similar to those found in Greenland and western Europe. This shows that the continents were once connected.

3. Summarize the ways that fossils helped to support the hypothesis of continental drift.
The fossils of reptile Mesosaurus was found in South America and Africa. But it only lives in fresh water and on land. If the continents were separated, then how could it have migrated? It must have swam to the other continent through fresh water. So this shows why continents must have been all connected.

4. Why would you expect to see similar rocks and rock structures on two landmasses that were connected at one time?
There are several requirements for a specific rock to be formed. If some type of rock formed between two countries, and then the continents were separated, then the two continents where it was once joined has same types of rocks. It is highly unlikeable that the rock formation was a coincidence.

5. Give an alternative explanation for why fossils of the same animal have been found on different continents. (This answer is not in your textbook).
Some animals were found on continents that were once connected. Some of these were the land animal. But if the Pangaea was false, then how could a land animal cross the ocean? So if the Pangaea actually existed, then the land animals could have simply walked over to the other continent.

1. Wegener used climate clues by finding out the evidence of climate changes like evidence of glaciers in America or Africa, which does not make sense if the continent was there long time ago.
2. Wegener found similar rock structures in different continents. This means that they were created in same ways and time, same situations, which leads to the conclusion that they were one body of land long time ago, when the rocks were formed.
3. Fossils helped supporting the hypothesis in many ways like fossil of widespread plants in different continents, or fossil of organisms that we know in what conditions they live.
4. Because when the land was formed they would had same thickness of sediments or other things that would form the land. So if there are similar rock structures, it usually would mean they were in same area once.
5. Animals that lived before the continents were divided would have moved around all over the Pangaea. When the continents divided, many animals were trapped in, and they became fossils.

1. Climate can be used as a clue of continental drift because things like old glaciers could be found in tropical areas.

2. when two rocks on coasts look like they could fit with another in a whole other country, it hints to continental drift.

3. when something habits a region but is found in two areas, the fossils hint towads continental drift.

4. if two landmasses were connected at one time. then the two landmass would have been formed simalarly.

5. animals could be in two places at once because they either had two habitats, or some were transported to another area somehow.
