Generally rough to touch, Helps in production of Heat and Electricity, Used as fossil fuel

Present

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.
