    How Is Coal formed?Process of Formation of CoalUses of CoalFossil FuelsFirst Stage PeatThis is the first stage in the formation of coal. It is an organic substance which is formed due to the partial decomposition of dead matter. The partial decomposition is due to the accumulation of the matter underwater which cuts off the oxygen supply.Second Stage LigniteThis is the second stage in the coal formation. It is a dark brown matter formed due to the pressure exerted by the sediments overlying the organic matter. It consists of traces of plantsThird Stage Bituminous CoalThis is the third stage in the formation of coal. It is formed due to the added pressure. This is also called as soft coal.See more on byjus
