Answer 15

Non renewable; although technically we don’t “use” the soil, we have a finite, or limited amount.

Question 18

Coal, crude oil and gas.

Question 20

How are fossil fuels created?

Answer 20

When plants die, they somehow get into a body of water, like a river or lake. Eventually they sink to the bottom and go underground. Then, heat and/or pressure is used to form the fossil fuel. The fossil fuel made depends on how much of both heat and pressure there is.

Question 21

How dangerous is nuclear energy?

Answer 21

Highly dangerous; it shouldn’t be handled by people who don’t know how to handle it. The radiation from the nuclear atoms cause people dying, and must be isolated unless you know how to handle it.

Question 22

What are power lines?

Answer 22

There are two types of power lines: Transmission lines and Distribution lines. When power is generated it gets sent to a substation on TRANSMISSION LINES. After, the substations distribute the electricity generated to the different homes and business. They use the DISTRIBUTION LINES to send the electricity to the homes and business.
