Coal | National Geographic Society

Jul 29, 2022Under the right conditions, peat transforms into coal through a process called carbonization. Carbonization takes place under incredible heat and pressure. About 3 meters (10 feet) of layered vegetation eventually compresses into a third of a meter (1 foot) of coal! Coal exists in underground formations called " coal seams " or " coal beds."
