Fuels: Coal Decaying plant matter, when buried under sediment, eventually forms peat (very moist, compact) Further compaction, over time, forces the
moisture out of the peat — forms a layer of lignite More compression (compaction), and more
moisture is removed, forming a layer of soft coal (bituminous)
Higher pressure and higher temperatures cause the bituminous coal to metamorphose into hard coal (anthracite
