Coal Natural Formation began in areas of swampy wetlands, in these areas layers of organic matter are accumulated and buried which leads to the formation of coal.
There are 4 stages of Coal Natural Formation: Peat, Lignite, Bituminous, and Anthracite.
Peat:
It’s a soft, crumbly dark brown substance that is formed from generations of dead and partially decaying “algae” yielding carbon dioxide and methane, plants are buried and no longer exposed to air, for several thousands of years the accumulation occurring leads to producing partially decayed plant matter known as “Peat”.
Lignite:
When peat is deeply buried, water and other compounds are squeezed out from the increase of pressure and temperature then the lowest quality of coal “Lignite” begins to form
Bituminous:
Continuous burial results in an increase of pressure and temperature which causes “Lignite coal“ to be transformed into higher-quality coal called“sub-bituminous” then into “bituminous”.
Anthracite:
Due to higher temperature and pressure, coal becomes denser and has higher carbon concentration which results in the highest quality of coal “anthracite”.
