coal forms when heat and pressure transforms plant material over millions of years. 1. Peat is particuly decayed plant material that somettimes look like soil. 2. Peat then becomes lignite, which is a sedimentay rock that is often called brown coal. 3. continued heat and pressure transforms lignite into bituminous coal or soft coal. Bituminous coal or soft coal. Bituminous coal is another sed. rock 4. Coals last stage of development is a metamorphic rock called anthracite or hard coal.
