  • Is coal a fossil?

  • It is made up of organic components; specifically, plant matter that has been buried in an anoxic, or non-oxygenated, environment and compressed over millions of years. Because it is organic, coal defies the normal standards of classification for rocks, minerals, and fossils: A fossil is any evidence of life that has been preserved in rock.

  • What is coal?

  • What is coal? Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.

  • How is CO2 coal different from other rocks?

  • Coal differs from every other kind of rock in that it is made of organic carbon: the actual remains, not just mineralized fossils, of dead plants. Today, the vast majority of dead plant matter is consumed by fire and decay, returning its carbon to the atmosphere as the gas carbon dioxide.
