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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
