What are the four stages of coal formation?

One. Organic material falls on the ground and is buried. It turns into bogpeat like stuff because of the anaerobic environment. Bogpeat like stuff eventually gets buried deep by seismic movement.

Two. Bogpeat like stuff gets compressed and heated. Water content decreases as water gets squeezed out. It becomes this weird kind of spongey stuff that makes good burning

Three. As time passes, it loses more and more water content and the proportion of hydrogen keeps on decreasing as carbon content keeps on increasing. It gets harder than a gentleman in your mother.

There are different stages of hardness and carbon richness. The longer coal is squashed, blacker, energy-denser, and clean burning it is.

Stage four is when some fucker like me sets it on fire to make power.
