Coal formed millions of years ago from the remains of plants that were buried and subjected to high pressure and heat over time. As the plant material decomposed, it transformed into peat, then lignite, sub-bituminous, bituminous, and finally, after millions of years, into coal. This process, known as coalification, occurs over geologic time periods.
