Question

Quizplus · Accepted Answer

Coal is formed from the remains of plant material that has been buried, compressed, and altered over millions of years. While some types of coal may contain small amounts of marine organisms, the primary source of coal is plant matter. Metamorphosed mafic minerals and blue-green algae are not significant sources of coal.
