1. I would expect to find a reverse fault since reserve faults result from the motion of compression which forces the plates to move up.
2. Rocks above the normal fault surface move downward relatively towards the rock below the fault surface.
3. Compression forces rock to move along a reverse fault because the rocks break which causes the surface to be forced up and over the rock below the fault surface.
4. It is easier to predict where an earthquake will occur because you can predict where an earthquake will occur by knowing where most earthquakes occur or how the earth is acting at a certain place while you never know when an earthquake will occur.
5. The chances of an earthquake increase because the fault lines are already made and it is easier for the earthquake to occur because the plates aren't entirely connected.
1. you would find reverse faults because the plates were forced together
2. they would move downward because of the tensional force
3. the rocks are squeezed together and have a reverse fault because one rock moves upward with the other going underneath it
4. we know where earthquakes will happen because we know where the plate edges and boundries are but we dont know when they will collide with eachother
5. when plates move apart they will soon come in contact with other plates

1)I would expect to find compression faults in the Himalaya. I would expect to find that because the Himalaya formed when two plates collided, and a compression fault forms.
2)Rocks move downward above a normal fault surface.
3)If a force squeezes two pieces of rock together hard enough something has to give. The rock moves along a reverse fault and goes down. The other rock goes up though.
4)It is easier to predict where an earthquake will occur rather then predicting when it will occur because of where it is on the continent plate. If a place is on the beach and right near the end of the continent plate it will have more earthquakes. It is hard to determine when an earthquake will appear because it starts in the ocean.
5)If an earth quake just happens that means the rocks were moving, which means they collided with another rock. It takes time for rocks to move into a different rock. Also if there were earthquakes every week in one place no one would live there.

1.If the two faults collided, it must mean that hey were pressed together, therefore it would have been a reverse fault.
2.Above a normal fault plates are pulled apart, and moves downward.
3.Rocks above a reverse fault are pushed upward and over the rock below the fault surface.
4.Earthquakes occur mainly near fault lines.
5.Earthquakes have after shocks?
1. Reverse faults would form when two plates collided and form mountains.
2. In normal faults rock above the fault surface moves downward in relation to rock below the fault surface.
3. When rock received compression forces that squeeze rock, it breaks from forces pushing from oposite directions and form reverse fault.
4. Since we have records from previous earthquakes, it is easier to predict where an earthquake will occur. However, we don't know when earth's crusts are going to meet so it is hard to predict when it will occur.
5. An earthquake is the vibrations produced by the breaking of rock. If an earthquake already occured last time, that means that earth plates are started to collide together. So the chances of an earthquake increase rather than decrease because it will happen again later on.

1. You would expect to find normal and reverse faults. In those, one of the sides will move upwards.
2. They would move downwards.
3. Compression forces that squeeze rock cause reverse faults. The compression moves rocks upwards.
4. It is easier to predict where an earthquake will occur because you can see where faults are and if there's lots of pressure there.
5. This is so because as time passes, more pressure increases. So then an earthquake is guaranteed.

1.)The types of faults would you expect to find in the Himalaya mountains in Tibet would be reverse faults because the direction of motion is upward, like a mountain.
2.)Rocks above a normal fault surface move downward, which is caused by the tensional forces inside Earth.
3.)Compression forces make rocks move along a reverse fault by squeezing the rock, causing it to break from the forces and push in two opposite directions.
4.)It’s easier to predict where an earthquake will occur than when it will occur because people have gathered knowledge about where the earthquake epicenters are and can tell by how mountainous and earthquake-prone the area is that earthquakes will probably strike there.

Answers
1. A reverse fault would be made because they are created when they push each other which is probably the same as colliding.
2. Rocks move in a downward relation to the rock below the fault surface.
3. The rocks push against each other. So a surface is forced up andor the rock below the fault surface.
4. That is because we know where the plates meet and usually the plates move and cause earthquakes. However, we don't know when an earthquake will occur just like we don't know what will happen to us in the future.
5. Since there was already an earthquake in the area, the land would be weaker and more vulnerable to earthquakes. So there might be more frequent earthquakes.
1.You may expect to see a reverse fault in these mountains because they were caused by collision and reverse faults form at these type of boundaries.
2.In a normal fault, the rocks above the fault will slide down and the rocks below will slide up.
3.In a reverse fault, the rocks are compressed and when one of them breaks away from that compression, it is forced upwards.
4.It is easier to pinpoint the location where an earthquake will occur then the time it will occur because people can find where the plates will rub against each other and where the plates are stuck. Also, a seismograph will indicate when the earth’s vibrations are getting larger in a certain area, but they cannot say when the earthquake will come, just that it’s coming.
5.As time passes since the last earthquake, the chances of another earthquake increase because right after that first earthquake, the rocks have broken apart and everything is back to normal and reshaped to fit, but as time passes, it will be likely that rocks will catch or collide again.

1. The Himalaya in Tibet formed when two of Earth's plates collided, called reverse fault. The reverse fault forms when the rocks break from the pressure forced on both sides.
2. The rocks move up and right, above a normal fault surface
3. The compression forces make rocks move along a reverse fault. The reverse fault forms when the rocks break from the pressure forced on both sides.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur. The focus sends waves, so people would know where the focus, or the location of the earthquake is. But it is more hard to estimate when it will happen because it happens without warnings.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake. After the earthquakes, there are secondary waves, or s-waves.
1. You would most likely find reverse faults in the Himalayas of Timbet. This is due to the fact that two rocks colliding together makes a reverse fault.
2. The rocks in a normal fault move away from eachother. The part of the rock above the fault moves downward in relation to the part of the rock above the fault.
3. Compression forces make rocks move along a reverse fault because when more pressure is added to something it will go over the other in the same way. It is not as with the normal faults where pressure is almost being released from the two where it will naturally move down.
4.It is easier to predict when an earthquake will occur because it is pretty simple to figure out what direction the two faults are moving at the same time. However, it is difficult to predict when rocks will get in the way of this proccess and how big of in impact this will make.
5. The chances of there being an earthquake increases rather than decreases as the time passes because the Earth does not stop moving. This means that during this time, the Earth is still moving. Its elastic limit has simply not yet been reached, but it will eventually be reached, increasing the chance of an earthquake.
1) Reverse fault, because they collide against each other
2) It moves downward.
3) They squeeze the rocks.
4) There is no way that tells us when a earthquake will happen. You can predict where it will happen by observing the faults and the regions where it happened previously.
5) The plates of the earth are moving. The continents are moving to different places and the ocean ground changes.
Chris E. Kim
1) It is the Reverse Fault, because it seems that they collide against each other.
2) It moves downward in relation to rock under the fault surface.
3) They squeeze the rocks and so change the direction.
4) A opportunity that tells us when earthquakes happen doesn’t exist. You could predict the location by looking at the faults and the areas where it happened before.
5) The ocean ground is changing and the plates of the Earth are moving.

1. If two plates collide you would expect to see a reverse fault. This is because when two plates collide, they are compressing, and a type of compression fault is a reverse fault.
2. In a normal fault, the direction of motion is going downwards diagonally.
3. Compression can cause reverse faults. The compression builds up on the rock and it breaks the rock and causes the force to move the rock upwards as apposed to how it normally would move if the rock wasn’t broken.
4. It is harder to predict when earthquakes occur than where they will occur. It is relatively easy to predict where earthquakes will occur. This is because you can just look at the major faults that are on earth’s surface and you can determine what type of fault it is. Using this information, you can predict where the focus and the epicenter of the earthquake may take place. It is harder to predict when earthquakes will occur because plates move at different rates.
5. The chances of earthquakes occurring increases as time passes since the last earthquake. This is because as more earthquakes occur, more fault lines are formed. These fault lines that are produced are most probably going to cause earthquakes in the future.
1. The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
Answer: You can expect to find reverse faults in these mountains. This is because when two plates collide, they are being compressed and reverse faults are caused when they are compressed.
2. In what direction do rocks move above a normal fault surface?
Answer: They move down.
3. Describe how compression forces make rocks move along a reverse fault.
Answer: Rocks above the reverse fault surface move up and those below the reverse fault surface move down.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
Answer: It is easier because earthquakes usually happen near faults but they can happen at anytime.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain
Answer:There are more chances of an earthquake to increase because there are seismic waves that travel through the Earth and bounce back and forth. Also, the rock along the faults are weaker so it can move more easily.

1. I would expect to find reverse faults in these mountains because when two of Earth’s plates collide, that means compression forces squeeze the rock and the rock above it is forced up and over the rock below the fault surface.
2. Rock above a normal fault surface moves downward in relation to rock below the fault surface.
3. Compression forces make rocks move above a reverse fault force upward and over the rock below the fault surface.
4. It is easier to predict where and earthquake will occur than it is to predict when it will occur because we already know where Earth’s plates are located so we can guess around where they will move.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because the plates were moved already so it might probably move at the same area.
1. I would expect a reverse fault at the Himalayas because I think that, when the Earth's plate collided, they compressed, and then formed the mountains they are today.
2. In a normal fault, rock above the fault moves downwards in relation to the rock below the fault, which moves upwards.
3. In a reverse fault, the compression forces the top layer upward, and the lower layer downward under the upper rock.
4. It will be easier to predict where an earthquake will occur because earthquakes almost always occur on faults between tectonic plates.
5. The chances of an earthquake increase because, since there is more rock under the ground, there is more to be broken, and more vibrations produced by the breaking of the rock.
1) When two earth's plates collide, like in the Himalayas, it is an example of compression forces which cause reverse faults. I would expect to find reverse faults in the Himalayas.
2) In a normal fault, Rock above the fault surface moves downward in relation to rock below the fault surface.
3) When rocks are compressed a reverse fault is formed and the rock above the fault surface is forced up and the rock below the fault surface moves down.
4) It is easy to see where forces are pushing along fault lines or where plates are moving together or apart because of seismic readings. It is difficult to know how elastic the rocks along the surface of a fault are though and exactly when they will break and cause an earthquake.
5) Since earthquakes happen along fault lines or where plates are pushing together or pulling apart, there is always force there. If an earthquake recently happened then that force was changed to force in motion. If an earthquake hasn't happened for a long time then scientists know force is building up and an earthquake could happen.

Benjamin Blades
1. you would expect to find reverse faults because the compression of the two plates colliding would move the layer above the fault surface upwards.
2. Rocks above a normal fault surface would move downwards.
3. Compression forces make rocks move along a reverse fault because the pressure applied on the rock forces rocks above the fault surface to move upwards and the other way around.
4. It is easier to predict where an earthquake will occur than to predict when because earthquakes will most likely be near where two plates meet or where there was already an earthquake. Earthquakes can happen at any random time and it is harder to predict an earthquake.
5. Chances of earthquakes increase because once the rocks move from its original position, it will be easier to move the next time.
1. I would expect to find a reverse fault because the two rocks are compressed together and one goes on top of the other forming mountains, like the Himalayas.
2. In a normal fault, the rock on the surface moves downward in relation to the rocks below the faults surface.
3. In a reverse fault, compression forces cause rock to move because the less dense rock moves on top of the more dense rock.
4. It is easier to predict where an earthquake will occur than when it will occur, because they are very sudden and can move at any time, but they are located at the plate boundaries.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because right after an earthquake the tension between the two plates is relieved. Then, the tension builds up again and the cycle repeats.
1. The Himalaya in Tibet formed when two of Earth's plates collided would be a reverse fault because the two plates are going the same direction which makes a plate go under another plate, creating mountains.
2. In a normal fault surface the top plate moves downward in relation to rock below the fault surface.
3. Compression forces makes rocks move along a reverse fault because the force that squeeze the rocks makes the plate be forced up and over the rock below the fault surface.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because you can predict from the past earthquakes but earthquakes are sudden so you can’t predict that.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because the past earthquake already shook the soil and since it’s loose there is a high chance that another earthquake will happen.
1) The Himalaya in Tibet formed when two of Earth's plates collided. This is a reverse fault surface because the forces are compressed together.
2) In a normal fault surface, the rocks move apart.
3) The compression forces make the rocks move along with the direction of motion
4) The places where an earthquake can strike lie in very certain areas and are relatively more easy to locate than when an earthquake will occur.
5) The chances of an earthquake increase rather than decrease as time passes since the last earthquake because every day rocks are being compressed, sheared, and tension and eventually will cause an earthquake.
1)Normal and reverse faults. Because, both faults create high lands.
2)Along a normal fault rock above the fault surface moves downward in relation to rock below the fault surface.
3)Because, if they push from opposite directions, rocks above a reverse fault surface is forced up and over the rock below the fault surface
4)When the earthquake is going to happen the force goes out and when people sense that, they can pin point where the earthquake is but cannot predict when it would happen.
5)Because more plates collide.

1.The types of faults that you could expect to find in these mountains is a normal fault and a reverse fault because when the earth vibrates the friction causes the plates to break from the forces pushing from opposite directions(reverse faults) and a normal fault is expected because the rocks create an uneven line, jagged, the surface moves downward in relation to the rock below the fault.
2.The direction rocks move above a normal fault surface is downward in relation to the rock below the fault surface.
3. Compression forces make rocks move along a reverse fault from the forces pushing from opposite directions. The rock above a reverse fault surface is forced up and over the rock below the fault surface.
4. It is easier to tell where an earthquake will occur because of it geographical features. It depend on whether it has faults and vibrations are created. An earthquake can occur randomly so it is hard to predict when it’ll happen.
5. Chances of an earthquake increase rather than decrease as time passes because when an earthquake occurs it damages the earth creating more faults and over time they will expand and will continually keep moving.
1. I would have expected to find a reverse fault and a normal fault. I chose the reverse fault because it is a upward movement and mountains are high up and rises up. I also chose the normal fault because not all parts of the himalayas have a high elevsation. There are some low areas so I chose the normal fault too.
2.The rocks above a normal fault surface move downwards.
3.Compression forces make rocks move along a reverse fault by squeezing the rocks and breaks from the forces by the both plates pushing from opposite directions.So the rocks would be forced up.
4.It is easier to predict where an earthquake will occur than it is to predict when it will occur because, people have tools to detect where the faults have halted. However, people do not know how fast or slow the speed is to predict when the earthquake will hit.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because one time there is an earthquake, the faults have a higher chance of having more earthquake because it is unstable. Also, rocks keep on moving so their will be more earthquakes.

1.) I would expect to find Reverse faults, because the mountains were formed from compression. The two plates were pressed into each other, which is most likely to create a reverse fault.
2.)Above a normal fault surface, the rocks move apart from each other, being stretched by tension.
3.) Compression forces make rocks move along a reverse fault, because as the compression force squeezes rock together, the rocks break from forces that are pushing from opposite directions, and they are forced up and over the rocks elow the fault surface.
4.) It is generally easier to predict where earthquakes will occur rather then when, because they can make relatively accurate guesses based on the earth's plates. However, the time of the earthquakes are generally unknown and very hard to predict.
5.) Chances of an earthquake increases as time passes, because the plates have more time to build up stress and pressure, and they can create faults again, due to the force that gets released from breaking rocks during a creation of a fault. As time passes, plates move, and that creates more pressure for possible faults.
1. The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
You would find reverse and normal faults in these areas. The reason is because in these areas the land rises because there are islands. The two types of faults causes land to rise upwards. While the other fault, strike-slip fault, leaves land flat.
2. In what direction do rocks move above a normal fault surface?
The rocks move to the left during a normal fault surface. The reason is because if you look from any of the two plates it seems as though the rock is moving to the left.
3. Describe how compression forces make rocks move along a reverse fault.
Compression forces are added to two faults. This causes for one rock to be pushed upwards while the rock layer declines.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
By using the speed of vibration in different points of the surface of the earth the epicentre of an earthquake can be easily found. However, the faults do not move at steady paces at one time and different amounts of pressure are always created which makes it difficult to predict an earthquake.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain.
If there was already an earthquake it shows that there are faults and plates moving. In areas of plate movement, the plates continue to move and cause more earthquakes instead of stopping after creating one earthquake.
1. You would expect to find reverse faults and normal faults. This is because the Himalayas formed colliding into one another. When reverse faults happen forces squeeze the rocks together making a rock move up over the other. This could be the fault that caused the high elevation in the mountains. You could also find normal faults because the motions formed in the normal faults pull up and down and towards the side. So, these faults could have caused the high elevation as well as the long length of the Himalayas.
2. The rocks above the normal faults move in a downwards direction and also to the side of the downwards rock.
3. The compression forces the rocks above the reverse fault surface to move upwards. The rocks move in an upwards direction because if the compression kept happening, the rocks would keep running into each other. The rocks would no longer have any space if they kept running into each other, so they move upwards as well as into the center.
4. It is easier to predict where an earthquake will occur than when it will occur because you can not predict when a fault will move. But you could predict where an earthquake is likely to happen according to plates, and previous earthquake epicenters.
5. The chances increase rather than decrease as time passes since the last earthquake because as earthquakes occur, the faults change is various different ways. And as time goes by more and more pressure builds up on the faults causing more chances of fault movement, possibly earthquakes.
1. The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
The types of faults you would expect in these mountains are reverse faults. The reason is, reverse faults is a motion that forces and squeezes a rock together. The force that pushes it from opposite directions is forced up and over the rock while it’s still below the fault surface.
2. In what direction do rocks move above a normal fault surface?
Rocks move in a downward way above a normal fault surface.
3. Describe how compression forces make rocks move along a reverse fault.
Compression forces make rocks to move along a reverse fault by squeezing the rocks .It pushes the rocks upward from the opposites sides.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
It is easier to predict where an earthquake will occur than it is to predict when it will occur because you can easily locate the earth’s tectonic plates. Earthquakes happen where the plates usually meet. However, you don’t know when the earthquakes really do occur.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain.
The chances of an earthquake to increase rather than decrease as time pass since the last earthquake is because the earthquake happens once a rock breaks off the faults. It than makes other rocks surrounded by it to also break. Eventually the whole rock structures starts to become weaker and it causes more earthquakes to occur.
1. I would expect to see either normal faults or reverse faults because they make the land go up which form mountains.
2. Rock above the normal surface move downward in relation to rock below the fault surface.
3. When compression forces squeeze the rock, the rock breaks forcing it to push from opposite direction. Rock abow a reverse fault is force up above the fault surface.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur. The earthquake occurs when forces keep driving the rocks to move causing it to buil up stress. This stress causes an earthquake and people can tell where that is happening but they do not know how much stress you need to cause an earthquake.
5. I think the chances of an earthquake increase rather than decrease as time passes since the last earthquake because the land below it gets less dense after an earthquake and that makes it easier for an earthquake to happen.
1)The types of faults that you would expect ton find in the Himalaya’s would be Reverse Faults. You would find reverse faults because the compression forces the rocks to squeeze.
2) In a normal fault surface rocks move downwards in relation to rock below the fault surface.
3) Compression forces make rocks move along a reverse fault because if the rock breaks from forces pushing from opposite directions, it causes the rock to break.
4) It is easier to predict where an earthquake will occur than it is to predict when it will occur because there are many major fault zones where earthquakes occur. We can predict that in those areas there will be another earthquake. We can also use instruments to predict where it might occur.
5) The chances of an earthquake increasing rather than decreasing as time passes since the last earthquake is because the more faults there are the more earthquakes will occur.
Terence
1. The types of faults that you would find in the Himalayas are reverse faults because on end gets pushed up into a mountainous shape and the surrounding area sinks.
2. In a normal fault, rocks move away from each other causing them to slide away but stay together.
3. Since the plates press against each other because of the compressional wave, the plates move up in the angle causing the plate more on top to rise.
4. It is easier to predict where the earthquake is than when it happened because after you figure out where it is, you can use the equation speed = distance/ time to find when it happened.
5. This is because as more time passes, the more pressure builds up and it kind of becomes time for a plate to move again.

1. The Himalaya in Tibet would have reverse faults because a reverse fault is when rock above the surface moves upsard relative to the rock below the fault surface due to compressive forces.
2. In a normal fault, rock above the fault surface moves downward in relation to rock below the fault surface.
3. Since more tension is added unto than subtracted, it brings the opposite effect as a normal fault.
4. Because earthquakes are very sudden and somewhat random, it is very hard to predict when it will strike. However where an earthquake might occur is easier because you know that you'll have to look along the fault lines (plate).
5. Because if an earthquake has occurred, it leaves more space in between the plates to move again.
1. Reverse fault would expected to find in Himalaya in Tibet. This is because reverse fault forms when opposite directions forces to push inside. This means if Himalaya collided, it must be pushing against inside.
2. Rocks above a normal fault surface moves downward.(direction)
3. Compressionforces make rocks to move upward in a reverse fault. The surface is forced up.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur. To do a prediction of where the earthquake would occur, scientists use seismographs to measure the vibraton. However, it is hard to determine when the earthquake would occur. This is because with the measurement of how long it would take from one place to another for a earthquake to vibrate more, it is hard to determine. Scientists usually have 3 points and then find the position and when.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake. This is because as time goes by, plates from each continent gets to be separated more and more. As a result, sea floor spreading could occur and more volcanoes and earthquakes would occur often.
1.It is a reserve fault because the rocks are beng forced upwards
2.the rocks in a normal fault moves down
3.the compression waves push the rocks together forcing the upper rocks up.
4.it is easier to predict where an earth quake eill occur because the fault lines show mivement but not at a constant speed
5.there are more and more earthquakes because the plates are moving more and more,

1. If Earth's plates collided, then the types of faults I would expect to find are compression and shear, because collision means interaction between the rocks.
2. Rocks move downward above a normal fault surface.
3. Compression forces can make rocks move along a reverse fault by squeezing the two rocks together until one slides over the other.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because we already generally know that earthquakes happen near plate boundaries.
5. Chances of an earthquake increases rather than decreases as time passes since the last warthquake, because having an earthquake means that the plates are moving, and it may be moving for a long while afterwards.
1. Would expect a reverse fault from the mountains of the Himalaya because it is the only type fault that makes the rock above the fault surface to move upwards.
2. Rock above the normal fault surface moves downward in relation to rock below the fault surface.
3. The broken rocks from forces that are pushing from the opposite direction the rock above the fault surface gets forced up and over the rock below the fault surface.
4. It is easier to predict where an earthquake is going occur than it is to predict when it will occur because people have already located and observed the epicenters of major earthquakes in the last few decades. But, it is very hard to predict when it is going to occur because no one yet knows how to.
5. It is more likely for the chances of an earthquake to increase rather than decrease as time passes since the last earthquake because when an earthquake strikes a continent, it means that a plate is moving is some direction, and at the same time it is pushing other plates to move. These movements of plates can also cause earthquakes.
1) The Himalaya in Tibet would have reverse faults, which are faults that result from compression forces that squeeze rock. Basically, the Himalaya are formed from convergent boundaries and reverse faults form in such areas.
2) The rocks above a normal fault surface move downward (in relation to the rock below the fault surface.)
3) Compression forces squeeze rock, and when two rocks converge, the one above the fault surface ends up going up whereas the one below goes downward. This basically forms a reverse fault.
4) It is easier to predict where an earthquake will occur because there is physical evidence from the plate boundaries. On the other hand, predicting when an earthquake will strike is quite impossible and unpredictable.
5) The chances of an earthquake increase (rather than decrease)because earthquakes release stored energy and energy gradually stores over a period of time.
1. The Himalaya in Tibet formed when two of Earth's plates collided. Types of faults I would expect to find in these mountains are faults. The reason why you would expect to find these faults is because it forced up and over the rock below the fault surface.
2. In normal fault surface, rocks move downward in relation to rock below the fault surface.
3. Compression forces make rocks forced up and over the rock below the fault surface.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because there is a system called seismograph that can measure the earthquake is occurred. However, there isn’t any system for predicting when it will occur.
5. Chances of an earthquake increase rather than decrease a time passes since the last earthquake because every time passes, continental plates are moving also. Also, it occurs seafloor spreading.
1. You would expect to find reverse and strike-slip faults. The reverse faults occur when two plates collide and one goes over and under each other. A strike-slip fault collides and moves past each other.
2. In normal faults, rocks move away from each other. One rock goes downwards.
3. Reverse faults are made from compression forces. With each compression, one rock slowly inches upward.
4. It is easier to predict where an earthquake will happen because there has been many earthquakes already, that gives us a relatively precise area, where earthquakes occur. Earthquakes can be out of nowhere. You cannot say for sure, when an earthquake will happen.
5. The chances increase rather than decrease since the last earthquake because earthquakes will constantly occur. The plates are on a continuous move. Even if plates move like an inch, it is still moving. So as long as plates move, there will always be earthquakes. Unless the plates just stop moving.
1. The types of faults that I would find in ‘The Himalaya’ are, reverse faults and strike-slip faults. You would find these faults because a reverse fault is formed when rocks are squeezed together, and when rocks get pushed together from opposite directions and a strike-slip fault is formed when either side of the fault are moving past each other without much upward or downward movement. Both of these faults may apply because in ‘The Himalaya’ because it formed when two of Earth’s plates collided.
2. Above a normal fault surface, rocks move in opposite directions. The tensional forces inside Earth cause the rocks to be pulled apart.
3. Reverse faults result from compression forces that squeeze rock. This is because rocks break from forces pushing from opposite directions.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because earthquakes occur on fault lines, and we know where the fault lines are, but we can’t always measure how much pressure on the fault line there is.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because the pressure of the plates increase as time passes, and the pressure needs to be released.
-Anjoulie W. Period C
1. You would expect to see a reverse fault. When the two plates collided the probably got pushed into each other. When the two came together one was pushed upward, causing mountains.
2. Rocks above a normal fault surface move downward in relation to rock below the surface.
3. When compression squeezes rock it causes rock above the surface to be forced up and rock below the surface to be forced under. This is because the rock is being pushed from opposite directions.
4. It is easier to predict where because we might tell where rocks are under stress or compression but we don't know when they are going to break or move.
5. The chances would increase because once they start to move under each other or break apart, they continue. They are more likely to keep moving under each other.
1. the fault would be a reserve fault because one platre would go under the other.
2.sufaces move to in realation to the below rocks.
3.if one work has more pressure then the other then one rock will be forced upwards.
4.a seismograph can detect waves and where they are but not how fast they are moving
5.as the contenints continue to move then there will be space for another colition.

1. I would expect to find 'Reverse' faults in the moutains. This is because the moutains rise up and reverse faults are when rocks surfaces move upward.
2. the rocks that are above the fault move down in relation to the rocks that are below the fault surface.
3. The rocks break from pressure from opposite sides and the rocks above are forced over the rocks below the reverse fault.
4. Because we know were earthquakes are most likely to occur which is along the edges of the earths plates.
5. Because more stress is aplied to the rocks around the fault. This stress slowly leads to its breaking point which is when a earthquake happens.
Nick. A
1) You would find reverse faults here because the Himalayas were formed when t o plates collided so that means they moved in an upwards direction.
2) In a normal fault the rock above it moves downward and the rock below goes up.
3) In reverse faults the compression force makes one rock go above the other because the force was so great that it didn’t break but went above it.
4) It is easier to predict where an earthquake will occur than when it will because scientist now that earthquakes occur on the edges of the plates.
5) Chances of an earthquake increase over time because as time passes rocks build up more stress on each other and are soon reaching its breaking point.

1. You would expect to see normal and reverse faults in this area because as the two plates collided one plate went up and one went down creating mountains and faults.
2. Above a normal fault surface the rocks would move downward.
3. Compression forces make rocks move along a reverse fault by squeezing rock.
4. It is easier to predict where an earthquake will occur than when it will occur because you can look at where earthquakes have occurred before in the area to tell where they will occur but there isn’t a pattern to when earthquakes occur.
5. The chances of an earthquake increase rather than decrease since the last earthquake is more likely because the plates have probably started moving in that area more.
1. I would expect to find reverse faults in the Himalayas because the plates collided, and a reverse fault is when the rocks are compressed together, and then one plate goes up, and on goes down.
2. Rocks above a normal fault move apart from each other.
3. Compression forces make rocks move along a reverse fault by squeezing the rocks, and by squeezing the rocks together some are forced up, and some are forced downwards.
4. It is easier to predict where an earthquake will occur than when an earthquake will occur because we know where plates boundaries are, and at plate boundaries is where earthquakes occur, but there is no way to predict when an earthquake is going to happen.
5. The chances of an earthquake increasing rather than decreasing as time passes since the last earthquake because the plates are still settling after there previous collision and they are still
moving, So, that is why the chances of an earthquake increase rather than decrease.
1) The types of faults you would find in these mountains are reverse faults. This is because reverse faults has motion that result from compression forces that squeeze rocks. If the rock breaks from these forces, rocks above a reverse fault surface is forced upwards and over the rock below the fault surface.
2) Rocks above a normal fault surface move downward in relation to the rock below the fault surface. This is because forces that are tensional under Earth’s crust cause rocks to be pulled apart.
3) Compression forces make rocks move along a reverse fault by squeezing the rocks and pushing from opposite directions. This causes the rocks to move upward to the surface.
4) It is easier to predict where an earthquake will occur than it is to predict when it will occur because you can easily find the location of the earth’s tectonic plates. When the plates meet, that is where an earthquake will occur. However, the time of occurrence is unexpected.
5) The chances of an earthquake increase rather than decrease as time passes since the last earthquake is because an earthquake results from rocks that break and move along the fault. Eventually, the rock becomes weaker and earthquakes become more frequent.
1. The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
A: In these mountains, we can see that it’s reverse fault because when two plates move towards each other, they forms mountain.
2. In what direction do rocks move above a normal fault surface?
A: The normal fault moves downward in relation to rock below the fault surface.
3. Describe how compression forces make rocks move along a reverse fault.
A: Compression forces the rock breaks from forces pushing from opposite directions. This is the reverse fault.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
A: Because we don’t know when exactly it will occur, however, there is this epicenter where it had been earthquakes before. Therefore, people can predict.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain.
A: it is because the places where had been earthquake before, the plates will bump each other, so, it won’t decrease, but might increase.
Su Ying Chang(:
1. A reverse fault is most likely to be found in the Himalayas. This is because reverse faults are formed when compression forces squeeze rock together. The Himalayas were formed when two plates colided, thus it is most likely to be a reverse fault.
2. Rocks above a normal fault move downward in relation to the rock below the fault surface.
3. Compression forces squeeze rock together, causing them to break. Thus, this forms a reverse fault, where the surface above the fault is pushed up and over the rock below the surface.
4. It is easier to predict where an earthquake will occur because earthquakes are more likely to occur along a fault. Thus, if a person knows where a fault is they may be able to predict an earthquake will occur in that area. However, to predict when an earthquake will occur a person will need to know exactly when rocks will break.
5. Chances of an earthquake increase rather than decrease after the last earthquake because rock in that area is loose, and earthquakes are "vibrations produced by the breaking of rock." Thus, since the rock is loose in the area where an earthquake has occured before, there is a higher chance that an earthquake will occur.
Justin K.
1. The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
MA: I would think that it is a reverse fault. Right now, the Himalaya mountains are constantly growing. I would guess that it is a reverse fault because one side is staying the same while the other side is going up due to the pressure. Also, since it is not normal fault (one side is staying the same while the other side is going down) or strike-slip fault (they aren't going up), I can conclude that it must be the reverse fault.
2. In what direction do rocks move above a normal fault surface?
MA: One side doesn't move very much but the other side moves downward.
3. Describe how compression forces make rocks move along a reverse fault.
MA: Two sides squeeze together and the pressure is built. As the pressure builds up, the rocks starts to be unable to hold the pressure. So the rocks suddenly release the pressure. And the rocks move along the reverse fault surface. As the compression forces keep pushing the rocks, one side keeps going up.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
MA: It is easier to predict where it would happen because as the pressure builds up, the grounds starts to vibrate. So you can predict that there's going to be an earthquake. But it is hard to predict when the earthquake will hit because you don't know when the rocks will suddenly release the pressure.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain.
MA: If earthquakes don't hit very often than before, it means that the two plates aren't moving towards each other anymore.
1. You would expect to see reverse faults in the Himalayas. A reverse fault's motion compresses a rock together. The force that pushes it is forced up and over the rock below the fault surface.
2. In a normal fault surface, rocks above the fault surface move downward in relation to rock below the fault surface.
3. If rock breaks from forces pushing from opposite directions, rock above a reverse fault surface is forced up and over the the rock below the fault surface.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because we know where the faults are but we don't know when they're going to move.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because it's more likely that the faults will move again since they already moved a little anyways.
Stephen Huh B Period
1. The Himalaya in Tibet formed when two of Earth's plates collided. The type of faults you would expect to find in these mountains are reverse faults because the Himalayas are mountains and reverse faults are pushed toward each other and the rock above the reverse fault surface moves upward and creates mountains.
2. Rocks that are above a normal fault surface move downward.
3. Compression forces make rocks move along a reverse fault because compression forces squeeze rocks together.
The rocks in a reverse fault are the plates and when the two plates squeeze against each other. One will go up and one will go down and create a reverse fault.
4. It is easier to predict where an earthquake will ouccur than it is to predict when it will because
tectonic plates do not move at a constant rate so the time they will create an earthquake is hard to predict. However, if you look at where two or more tectonic plates are and how they move against each other an earthquake will happen but the time cannot be accurately known.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because the pressure between the plates increase over time and soon the elastic limit will be surpassed.
1. The types of faults you would expect to find are the ones that go up and down which are the convergent ones.
2. From a noraml fault surface, the rocks would move upward.
3.Compression forces make rocks move along a reverse fault. They collide and push so forcefully that one plate goes up and another goes down.
4. It is easier to predict where an earthquake will occur rather than when it will occur because you can calculate the epicenter using a method.
5. The chances of an earthquake increases rather than decreases as time passes since the last earthquake because it gets stretched further and further like a rubber band.
1. You would see reverse faults in the Himalaya in Tibet because reverse faults result from compression forces that collide or squeeze against the rock(s), which was the same process that was occurring when the Himalaya in Tibet formed.
2. Along a normal fault surface, rock moves downward in relation to rock below the normal fault surface.
3. If rock breaks from [the compressing] forces pushing from the opposite directions, rock above a reverse fault surface is forced up and over the rock below the fault surface.
Source: Earth Materials and Processes, Chapter 5 Section 1.
4. It is easier to predict where and earthquake will occur rather then when it’ll occur because you can locate the various fault zones or areas of where faults have been formed. However, there is no indication or sign [seeing from above the Earth’s surface] of when an earthquake will occur.
5. The chance of having another earthquake after time passes since the last earthquake increases because after an earthquake occurs, the surrounding rock of the rock that caused the earthquake (collision of plates) tends to weaken. This is what creates aftershocks of an earthquake.
1. I would expect the fault to be a reverse fault, seeing as land may have been pushed up to form the mountains.
2. They move away from each other.
3. Compression forces rocks together on a reverse fault.
4. Most earthquakes happen on faults, so the location of an earthquake is almost a given. When it will occur is not.
5. No matter what, the forces of shear, compression, and tension will never be stronger/weaker than they were. However, the rocks have either already broken, or have bent to the point where it will take less force to break.
1. Reverse Fault because they push upward, and mountains are higher than the land surrounding.
2. Rocks move downward above a normal fault surface.
3. Compression forces squeezes the rock and forces it up over the rock along the reverse fault.
4. It is easier to predict where an earthquake will occur than when it will occur because earthquakes usually happen where faults are which we already know where they are.
5. Earthquakes develps more stress, which makes the earthquakes occur more.
1) You would find reverse faults in the Himalayas because they were formed when the two Earth plates collided, and reverse faults happen when rocks are squeezed through compression.
2) On a normal fault surace, rocks above the fault move downwards.
3) During a reverse fault, rocks may break due to the forces pushing from opposite directions. If these rocks are above the reverse fault, it is forced upwards over the rock below the fault surface.
4) It is easier to predict where an earthquake will happen because we know that earthquakes are likely to occur near the plates of the Earth's surface. We know this becuse the Earth's surface in constantly in motion, and this causes the plates to move. This puts stress in the rocks near the edge of the plates, and so, the rocks tend to bend, compress, or stretch to relieve this stress. This causes earthquakes.
5) It is easier to predict where an earthquake will happened rather than when because when there is an earthquake, the plates will move, creating boundaries and faults. This movement happens again and again, which is why it's likely that an earthquake will be likely to happen as time passes the last earthquake.
1. I would expect to find a reverse fault because reverse faults result from compression forces. When 2 plates collide, they are being squeezed together.
2. Rock moves downward above a normal fault surface. This is caused by tensional forces inside Earth that causes rock to pull apart.
3. Compression forces squeeze the rock causing it to move along a reverse fault.
4. It is easier to predict where an earthquake will occur rather than when it will occur because scientists have evidence that many earthquakes occur in different areas. For example, near the Ring of Fire, there are many earthquakes because of the chain of underwater volcanoes. Since scientists have found this “hot spot” they know what area the earthquakes will happen.
5. The chances of an earthquake increase because the plates could possibly be still moving at an unsteady pace and there could be another earthquake.
Joshua G
Period D
1.The Himalaya in Tibet formed when two of Earth's plates collided. What types of faults would you expect to find in these mountains? Explain.
The types of faults you would expect to find in the mountain Himalaya are reverse faults because in reverse faults the surface is forced up. When the rocks are forced high enough they can be called mountains or plateaus.
2. In what direction do rocks move above a normal fault surface?
In normal faults the rocks move in the direction, left.
3. Describe how compression forces make rocks move along a reverse fault.
Compression forces make rocks move along a reverse fault because compression forces cause pressure upon the rocks to make it forced up. This happens when the rocks the rocks move In different directions, one goes up, one goes down.
4. Why is it easier to predict where an earthquake will occur than it is to predict when it will occur.
It is easier to predict where an earthquake will occur than it is to predict when it will occur, because seismographs can record the time and figure out the time when the seismic waves were spread. The reason why it is hard for people to find the time of the earthquake, because it is not possible to monitor the plates, since it is underground.
5. Why do the chances of an earthquake increase rather than decrease as time passes since the last earthquake? Explain.
The chances of an earthquake increase rather than decrease as time passes since the last earthquake, because the plates are not stable and they have completely stopped moving. Since the plates have moved and are unstable, because of subduction, there is a greater chance of an earthquake to occur as time passes.
1. Types of faults that you would find would be a reverse fault and a normal fault. But you would not find a strike slip fault because a it barely has an upward/ downward movement.
2. On a normal fault surface the rocks above the flat surface move downward.
3. Compression forces make rocks move along a reverse fault because the compression force squeezes the rocks together causing the rock above the reverse fault surface to move upward compared to the rock below the rocks' fault surface.
4.It is easier to predict where an earthquake would occur rather than when it would occur because scientists could infer where the location would be using the epicenter. Also scientists know that most earthquakes occur near the plate boundaries, so there is more information and technology provided to help make an educated guess. But an eathquake's occurence ranges from unnoticeable to devastating waves of energy.
5. The chances of an eathquake increase rather than decrease as the time passes since the last earthquake because everytime an earthquake appears, it triggers a new one below the earth's surface and also the vibrations can stay in some places longer than others causing some cracks and changes in the plates movement.
1. I believe that a normal fault and a reverse fault can be found in the Himalayas. It's because the normal fault is when two surfaces pull appart from each another. This causes a rock surface to move downwards and that surface pushes the opposite side of the surface upwards. This is one potential of forming the Himalayas. Another potential is the reverse fault, when a two surfaces squeeze against each other. This causes a rock surface to move on top of the surface on the opposite side.
2. The rocks above a normal fault surface moves appart from each other
3. The compression forces make rocks move along a reverse fault to move upwards each other. One rock moves upwards on top of the surface below the fault.
4. It is easier to predict where an earthquake will occur than when it will occur because earthquakes usually happen at the same location repedidly.
5. The chances of an earthquake increases as time passes since the last earthquake because the faults become more and more unstable as time passes and the surfaces continue to move appart or against each other as time passes.
1. In the Himalaya in Tibet, a reverse fault is expected to be found, because the high mountains were formed by the rock above the surface moving upward in relation to the rock below the fault surface.
2. Rocks above a normal fault surface moves downward.
3. Compression forces make rocks move upward along a reverse fault.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur, because most of epicenters are located near plate boundaries.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake, because during a long period of time without any other earthquakes, the plates will move or change shape, which makes them easier to get caught to each other's surfaces.
michelle k d period
1. You would find a reverse fault in the Himalayas because they were formed by two plates being pushed together.
2. rocks above normal faults are forced upwards.
3. compression squishes to rock faults together, so they have nowhere to go but up and down.
4. Its easier to predit where an earthquake will transpire rather than when because earthquakes usually occur at the borders of plates.
5. The chances of an earthquake increase as time passes because right after an earthquake, the two plates just had rocks broken off. This means the plates colliding again will take longer, rather than quicker.
1. Reverse Faults that sends some techtonic plates upwards and others downwards, when they collide into each other.
2. Rocks move away from each other in normal faults.
3. reverse faults are slanted so when pressure is added one moves up and the other moves down.
4. Earthquakes will appear near techtonic collisions or seperations, but the time is always random.
5. Chances increase because the techtonic plate has started to move and will continue more frequently.
1. You would expect a reverse fault, because the lands moved upwards and then collided.
2. A normal fault will move downwards.
3. A reverse fault will move upwards.
4. It is easier to predict where an earthquake happens instead of when because earthquakes happens near the plate boundaries.
5. The chances of an earthquake increases overtime because, the plates moves constantly.
Martin-
1. You would expect to find a subrmergent thing in those mountains because one plate went under the other one.
2. Rocks move north above a normal fault surface.
3. Compression forces can be a major factor in reverse faults. It is the main cause depending on how the pressure is added and the compression forces are used.
4. It is easy to tell where because you know where plates collide and where they have many earthquakes. Example: you wouldn't say there'd be an earthquake in Korea whereas in Japan. The time is harder to calculate.
5. Because the plates are closer to each other resulting in a possible next earthquake.
1. You would expect the Himilaya in Tibet has a normal fault type and you can expect to find many metamorphic rocks.
2. The direction of rocks that move on a normal fault surface is when the rocks pull apart from eachother creating eachother to create a gap. Another way to explain this is how there is tension.
3. Compressional forces push the rocks from opposite sides and the rocks are forced upwards.
4. It is easier to predict where it will happen because we know where the faults are for example we know near the pacific ocean will have many earthquakes but it will be harder to know when it will happen. Also scientists have methods on how to find the exact location.
5. The percentage increases because of the more time passes the more earth moves causing more earthquakes to occur.
1. I would expect to find reverse faults because result faults are faults that are resulted from compression forces like colliding plates.
2. They move downward.
3. Compression forces make the rocks collide and squeeze so that the rocks break and move, causing reverse faults.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because we know that earthquakes generally happen where the plates meet.
5. The chances of an earthquake increase rather than decrease as time passes since the last earthquake because then stress and yension in the rock builds up as time goes by.
Nina C.
A Period
1. The faults you would expect to find is the reverse fault. The reverse fault is when the two rocks move towards each other, one going ontop and the other going on the bottom. It would form the Himalayas because when two plates make mountains or places like that, they move towards each other, and thats what the reverse fault does.
2. In the normal fault thing, the rocks move away from each other.
3. Compression forces make rocks move along a reverse fault by having them compressed together, they might pile ontop of eachother and go one way each.
4. It is easier to predict where an earthquake will occur because there are alot of large fault lines exposed where most earthquakes are, and also most earthquakes are found near the edges of plates. It would be harder to figure out the time when it will happen because there would have to be really really modernized electronic systems that could tell when an earthquake would happen a few days before it would actually happen.
5. The chanses of an earthquake increases after the last earthquake because the ground shakes and moves the rocks more, which might make them move again to create another earthquake.
1)One would expect to find a reverse fault in these mountains because reverse faults are made by compressional movements (like a slinky or an accordian) that force plates upwards and together.
2)Rocks move downwards above a normal fault line.
3) Compressional forces make rocks move along a reverse fault line by being pushed up and over rocks below the surface of the fault.
4) It is easier to predict where an earthquake will occur than when it will occur because the areas of where an earthquake start will most probably originate from the earthquake prone areas such as the Ring of Fire or near the San Andreas fault, anywhere near the fault lines or edge of tectonic plates.
5)This is because the surface of the earth is continuously changing, in other words, after an earthquake, the land it has struck becomes weaker, rocks break, causing the land to become more earthquake prone.
1. The types of faults that you would find in the Himalayas are reverse faults because on end gets pushed up into a mountainous shape and the surrounding area sinks.
2. Rocks above a normal fault surface moves downward.
3. A reverse fault will move upwards.
4. It is easier to predict where an earthquake will occur than it is to predict when it will occur because we know where the faults are but we don't know when they're going to move.
5. The chances of an earthquake increasing rather than decreasing as time passes since the last earthquake because the plates are still settling after there previous collision and they are still
moving, So, that is why the chances of an earthquake increase rather than decrease.
