With population increase, fossil fuels are being used more and more daily. What hypothesis can be made about how that affects temperature and carbon dioxide?

• If fossil fuels are used, then it has no effect on carbon dioxide or temperature.

• When fossil fuels are used, then the carbon dioxide decreases and the temperature increases.

• If fossil fuels are used, then the carbon dioxide and temperature both decrease.

• As fossil fuels are used, then the carbon dioxide and temperatures both increase.

What could be an advantage of using coal energy?

• Produces large amounts of energy and is easy to transport

• Free to use

• Does not cause pollution

• Can be used to produce plastics

Electricity is very important to people because

• It can be turned into other energy types- geothermal, solar, hydropower, wind

• It can't cause pollution

• It can be turned into other energy types- motion, sound, light, heat

• You can find it naturally occurring in the environment
