How is coal formed?

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants - giant ferns, reeds and mosses - grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.

OKD How coal was formed

How coal was formed. Coal was formed in Paleolithic era ecosystems ( lake basins, river deltas or low lying areas ) and is made of the material of prehistoric plants. Initially, through solar energy they produced hydrocarbons from air, water and mineral matters. Upon decay they sank into the swamps which were environments without oxygen.They could not decompose by normal biological processes.

Coal formation - Energy Education

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.

coal - Origin of coal Britannica

coal - coal - Origin of coal: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should be noted that peat can occur in temperate regions [e.g., Ireland and ...

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earth’s surface, the coal itself may be eroded away, and either “eaten” by bacteria, or buried in new rocks. And, occasionally, a natural forest fire or a lightning strike may set coal on fire.
