They were formed over millions of years, from the remains of dead organisms:

  • crude oil and gas were formed from dead sea creatures
  • coal was formed from dead plants

Crude oil is found trapped in some of the sedimentary rocks of the Earth's crust.

Millions of years ago, huge numbers of microscopic animals and plants - plankton - died and fell to the bottom of the sea. Their remains were covered by mud.

As the mud sediment was buried by more sediment, it started to change into rock, as the temperature and pressure increased. The plant and animal remains were ‘cooked’ by this process, and slowly changed into crude oil.
