the remains of plant matter is changed into coal over millions of years while the remains of billions of microorganisms and other organisms formed petroleum and natural gas.
Wood is formed from plant matter like trees; coal is a type of rock that is formed under great pressure over millions of years.
Coal is formed over millions of years by pressure and heat on decomposed vegetation accumulated in shallow swamps, the result is a sedimentary carbonaceous rock known as coal...
