What are fossil fuels?

Back

Natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas.

Front

What is solar energy?

Back

Energy harnessed from the sun's rays, which can be converted into electricity or heat.

Front

Why are fossil fuels considered nonrenewable?

Back

They are formed over millions of years and cannot be replenished within a human timescale.

Front

What happens when fossil fuels run out?

Back

We will need to use more renewable energy.

Front

What is geothermal energy?

Back

Energy derived from the heat stored beneath the Earth's surface.
