Coal is a sedimentary rock that is formed from the remains of plants found mainly in underground deposits. This hard black rock is mostly made up of carbon and also contains sulfur, hydrogen, nitrogen and oxygen. Coal forms from the accumulation of plant debris, mostly in a swamp environment. When a plant dies and falls into a swamp, the water of the swamp protects it from decaying.
