What Are the Four Stages in Coal Formation?

Mar 30, 2020· Stage two of the coal formation process is lignite. Lignite forms when peat is put under considerable vertical pressure. It contains small amounts of plant matter and is very fragile so it must never be handled before burning. Bituminous coal is the third stage of coal production. The lignite continues receiving heavy vertical pressure until it

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.在byjus上查看更多信息
