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.
