Which nonrenewable resource causes the least air pollution? | Natural |
List the nonrenewable resources. | Coal, natural gas, and petroleum |
Why are people trying to use alternative energy resources? | Because they will run out before more is made, and causes alot of air pollution. |
Which do people use more of today, renewable or nonrenewable resources? Why? | Nonrenewable,because create less pollution. |
Which renewable resource indirectly affects wind and hydropower? Explain. | Solar energy |
Explain how fusion and fission make energy. | Fusion atoms combine, and fission atoms split. |
What is the major advantage of fossil fuels? | Small amounts= lots of energy |
Drilling wells on the Ocean floor removes which fossil fuel? | Oil |
What is coal made from? | Ancient plant remains (peat) |
What are natural gas and petroleum formed from? | Ancient microscopic sea organisms. |
Which fossil fuel is used the most in the U.S.? Which is the most abundant in the U.S.? | Oil is used the most, but coal is the most abundant. |
What is the major disadvantage of natural gas? | It is very flammable. |
How does hydroelectricity create electricity for people? | Has to have moving water. |
What does energy conservation mean? | Save what we have only using what is necessary. |
Which renewable resource is the most widely used today. | Hydroelectricity |

What is a major disadvantage of wind energy? | Some areas don't have enough strong wind, and the wind could be unpredictable at times. |
What is a problem of building dams for hydroelectric energy? | Dams are a problem for hydroelectricity because, this would stop the rushing flow of water and this wouldn't create energy -harm the environment. |
