Coal forms when dead plant material builds up and up to form peat, which is the first step. This is compacted between layers of sedimentary rock, forming a rock called lignite. Then this is compacted even more. Then, heat and pressure deep deep beneath the surface create anthracite, or coal. Coal is a metamorphic rock.
