1)The atoms combine which means fusion inside the sun, then they travel up and create that energy.
2)The sun heats the earth un evenly so that creates winds in the air.
3)Most of the oil and gasses are found under the sea.
4)Biomass is considered to be renewable becuase we have so much trash we can burn and we can also burn some wood if needed.
5)The sea snake gets it energy from the waves. The sea snake moves with the water so when waves go the snake bends and absorbs the energy with its pistons.
6)Food and batteries are two ways to store energy.
7)Sulphuric acid is used inside the car and lead is used as the metal. H2SO4 thats the chemical equation

1) The source of solar energy is produced during thermal nuclear reactions in the center of the sun.
2) The source of energy from the wind comes from the sun's energy. Because it does not heat the surface of the earth evenly, it causes variations in air pressure that result in winds. These winds can be used to generate wind turbines to generate electricity.
3) Most of the earth's reserves of oil and gas are found under the seabed. They are eventually released from drilling and pumped through pipelines into factories.
4) Biomass is considered to be renewable energy resources because new trees are being planted to replace the ones that have been used to create fuel.
5) The sea snake produces energy by using hydroelectric pistons that are attached to large joints that moves with the motion of the waves. The wind creates these waves.
6) One store of chemical energy is fuel such as petrol, which is made from oil and gas. Food is another source of stored chemical energy.
7) The type of acid inside a car battery is sulphuric acid. The metal that is used inside a car battery is lead. The chemical formula for sulphuric acid is H2SO4.
8) The names of three copper containing minerals are chalcopyrite, bornite, and malachite.
9) The countries with the largest copper resources are Canada, Chile, and USA.
10) Coppers with 1% impurities are not suitable for most applications.
11) During the process of electro refining, the pure copper forms on the cathode.
12) Titanium is the 9th most abundant element in Earth's crust, which is about 0.6%.
13) Titanium has many properties that make it valuable. Titanium does not corrode or deteriorate, and it is very dense. Titanium alloys are very comparable to iron or steel because they can be used in applications that require low densities and high resistance to temperate changes. Titanium is very strong and it has a very high melting point, which is why titanium often replaces steel. Titanium also doesn't cause allergic reactions, which is why it is often used to make jewelry.
14) Final impurities are removes by heating the titanium at a high temperature. This causes magnesium chloride to vaporize and escape resulting in pure titanium.

10. Is copper with 1% impurities suitable for most applications?
Copper with one percent impurity is not suitable for most applications, because the copper has to be completely pure in order to get good conductors.

11. In the electorefining of copper, does the pure copper form on the cathode or on the anode?
In the electorefining of copper the pure copper forms on the cathode.

12. How abundant is titanium in the earth’s crust?
Titanium is a relatively common element. It covers about 0.6% of the earth’s crust.

13. What properties of titanium make it valuable?
The properties of titanium that make it valuable is that it is less reactive than aluminum, but more reactive than iron, it does not corrode or deteriorate, not as dense as iron, it has a melting point higher than iron, and it is as strong as iron or steel. It is also much lighter. This makes titanium valuable and it is used mostly in aircrafts.

14. How are the final impurities removed from titanium it is being refined?
Final impurities are removed from titanium by removing oxygen from the titanium. It is done by first changing the titanium dioxide into titanium four chloride. Then it is put into a furnace containing molten magnesium. The magnesium removes the chlorine, but there are many impurities containing inside the titanium of magnesium. It is then burned at a high temperature where magnesium ifs vaporized. Now the titanium is close to being perfectly pure.

1.) The energy of the sun comes from thermal nuclear reactions that occur in the center of the sun.

2.) Wind turbines generate electricity by converting the movement of air into electric energy. The source of this wind is from the sun. The sun doesn't heat the Earth's surface evenly, causing differences in air pressure, which then creates wind.

3.) Reserves of oil and natural gas are usually found under the sea bed, because oil and some fuels are formed from dead sea animals, or plants.

4.) Biomass is considered to be a renewable energy source because you use wood, and other things to create energy by burning it and wood can be restored if used wisely. Instead of cutting down trees recklessly all at once, you can take a few at once, so you give it enough time to grow back in a forest or a good condition.

5.) A Sea Snake produces energy by using hydrolic pistols that are attached to large joints, which move with the motion of the waves.
