Non-renewable resources that formed over millions of years when prehistoric plants and animals died and were gradually buried by layers of rock.

An energy source that CAN be easily replenished (you can get more of it easily)

An energy source that can NOT be easily replenished (you can not get more of it easily)

Solar energy comes from the

Heat from inside the earth creates

Energy from flowing water is called

Most of the energy consumed in the United States is from ___________________ energy sources:

Crude oil, natural gas, and coal are called ____________________ because they were formed over millions of years by the action of heat from the earth's core and pressure from rock and soil on the remains (or fossils) of dead plants and animals.

__________________ energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity.

Energy sources are classified as ____________________ because they do not form or replenish in a short period of time.

__________________ energy sources such as solar and wind replenish naturally in a short period of time.

The four major nonrenewable energy sources are: Crude oil, Natural gas, ____________ , and Uranium (nuclear energy)

Coal, crude oil, and _______________________ are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago.

There are five commonly used renewable energy sources: Biomass, Hydropower, Geothermal, Wind, and ___________________

In general, renewable energy is more expensive to produce and to use than fossil fuel energy.

Renewable energy plays an important role in reducing _____________________ emissions.

Which of these is NOT a disadvantage to using fossil fuels?

Where would we most likely find and use geothermal energy?

Where would we be most likely to find and use hydropower energy?

You use and rely on fossil fuels EVERYDAY.
