Nonrenewable energy source such as coal, oil, & natural gas

Fossil fuel formed from marine organisms often found in folded or tilted layers and used for heating & cooking

Amount of a fossil fuel that can be extracted from Earth at a profit

Liquid fossil fuel formed from marine organisms burned to obtain energy & used to manufacture plastics

Electricity produced by water power using large dams in a river

Alternate energy source based on splitting of heavy atoms into lighter ones & releasing energy

Inexhaustible energy resource that uses hot magma or hot, dry rocks below earth

Renewable energy derived from burning organic materials such as wood & alcohol

The process of splitting atoms

Sources of renewable energy that are constant and will not run out in the future.

Soft, brown coal that is about 70% carbon, the second stage of coal formation

Black, brittle coal that is used most often, third stage of coal formation

Process of combining atoms

First stage of coal production consisting of decayed organic matter

When layers of soil & rock above coal are removed & the coal is taken out of the ground

The last stage of coal formation, it's the cleanest burning coal.
