No. Some limestones and amber are others.
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.
Basalt is an organic biogenic sedimentary rock that forms from the cooling of magma. It is not coal, sandstone, or conglomerate, which are sedimentary rocks formed from the accumulation and cementation of organic debris, sand particles, and mixed rock fragments respectively.
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.
Yes, coal is considered an organic sedimentary rock. It is formed from the remains of plants and trees that have undergone a process of burial, decomposition, and carbonization over millions of years.
Organic rocks are formed from the remains of living organisms, such as shells, plant materials, or animal remains. These rocks tend to have a high content of carbon and are typically sedimentary in nature. Examples include coal and limestone.
No. But a Sedimentary rock, Organic.
Coal is considered a rock because it is a sedimentary rock formed from the remains of plants in ancient swamps and marshes. Through a process called coalification, the organic material in the plants is transformed into coal over millions of years due to heat and pressure.
Coal is a type of organic sedimentary rock formed from dead plants.
