Fossil fuels are fuels such as OIL, GAS and COAL. They are all found under the ground.

OIL and GAS were formed together. They are formed from Dead Sea creatures e.g fish. Millions of years ago when the sea creatures died they sank to the bottom of the sea bed, there they got covered by sand. The sand over many years turned into rock and the Dead Sea creatures eventually turned into oil and gas.

COAL was formed by dead plants. When the plants died they fell into a swamp. There they got covered by mud and gradually the dead plants turned into coal.

Fossil fuels are non-renewable which means that it will all run out one day.
