Coal comes from a process called coalification. During this process peat which is plant parts, roots, bark, spores and other things decay. The peat becomes compact and buried by sediment. This is the first step to coal formation. You can find more information here: http://www.minepermits.ky.gov/miningeducation/coal_formation.htm
