5 Formation
5.1 Formation
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
