coal organic matter

UCSB Science Line

Answer 1: Technically, coal could be formed by any type of organic matter. Organic matter includes stuff that is alive or used to be alive, including plants, animals, bacteria, insects, etc. One reason why coal deposits are formed from dead plant material is that there are simply way more plants than animals on land.

Coal vs. Wood vs. Coconut Carbon Filters | CB Tech

Bituminous coal forms when lignite coal is subjected to high pressure. For this reason, it is found in nature as an organic sedimentary rock and is the result of a peat bog that was compressed long ago. It has a carbon content of between 70 and 90 percent. However, coal-based carbons are still not the strongest candidate for several reasons:
