Coal is considered an organic sedimentary rock, except for anthracite which is considered a metamorphic rock.
Coal is not a rock, but rather a sedimentary organic rock that forms from plant debris. It is comprised of organic matter like carbon, hydrogen, and oxygen, making it different from inorganic rocks which are formed from non-living materials.
Coal is a type of organic sedimentary rock formed from dead plants.

Coal is considered a rock because it is a solid, naturally occurring material formed from organic matter over millions of years. Despite its organic origin, coal's composition and characteristics classify it as a rock due to its hardness, density, and structure.
Coal is a rock derived from organic processes.
yes, a organic sedimentary rock
Most coal is classified as an organic sedimentary rock. The exception would be anthracite, which is metamorphosed bituminous coal.
Coal
Coal is an organic sedimentary rock because it is derived largely from the remains of plants.
Anthracite could be considered an organic metamorphic rock as its protolith is bituminous coal, an organic sedimentary rock.
Coal is not a rock, but rather a sedimentary organic rock that forms from plant debris. It is comprised of organic matter like carbon, hydrogen, and oxygen, making it different from inorganic rocks which are formed from non-living materials.
No. But a Sedimentary rock, Organic.
Coal is a type of organic sedimentary rock formed from dead plants.
Coal is an organic rock that is composed of vegetation that may have originated in swamps and marshes.
Organic sedimentary rock is derived mostly from the remains of organisms which have lithified into rock. Examples would be coal and chalk.
Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.
Coal, other than the metamorphic form called anthracite, is an organic sedimentary rock.
