FOSSIL FUELS
Coal, petroleum and natural gas are fossil fuels.
We extract coal from mines and petroleum from oil fields.
Natural gas is found in deposits deep beneath the surface of the Earth.
Petroleum is used to produce fuels, plastics and other products.
Natural gas and coal are used directly as fuels to produce electricity.
