Faahfaahinta casharka

Natiijada casharka

I can describe what coal, oil and natural gas are, how they formed, and why they are non-renewable energy resources.

Muuji qoraalka

Coal is a sedimentary rock that burns because it is made mostly of carbon, with some impurities. Coal is formed from deep sediments of organic matter made of prehistoric plants. Oil and gas formed from dead plankton mixed in with sediments that formed millions of years ago. Oil and natural gas are found in pores of sedimentary rock. The organic matter that formed coal, oil and natural gas decomposed into hydrocarbons.
