All About Coal Formation!
Coal
beds consist of altered plant remains. Growth began in forested swamps
and when they died, they sank below the water, beginning coal formation.
There
are four stages in its formation: peat, lignite, bituminous and anthracite.
The stage depends upon the conditions to which the plant remains were
subjected after they were buried. The greater the pressure and heat,
the higher the rank of coal. Higher-ranking coal is denser and contains
less moisture and gases and has a higher heat value than lower-ranking
coal.
