Organic
Coal is primarily made of organic material that has been subjected to heat and pressure over millions of years. It is formed from the remains of plants that have been buried and compressed.
Tufa is a clastic chemical sedimentary rock formed by the precipitation of calcium carbonate from water. It is not organic in origin, as it is created through inorganic chemical processes rather than from the remains of living organisms.
Basalt is a type of igneous rock that is formed from the cooling and solidification of lava. It is considered a chemical sedimentary rock, as its minerals crystallize directly from magma and do not involve the accumulation of organic or clastic material.
It doesn't really have one. Coal is a complex mixture of organic compounds with traces of inorganic and metallic ones too.
Coal is a mixture, as it is composed of a variety of organic compounds, minerals, and other substances. It is not a single chemical element or compound.
It is clastic
clastic
Coal is primarily made of organic material that has been subjected to heat and pressure over millions of years. It is formed from the remains of plants that have been buried and compressed.
It is none of these. Clastic, organic, and chemical are terms for classifying sedimentary rock. Rhyolite is igneous.
None of the above. These terms describe sedimentary rocks. Granite is igneous.
chemical
Bituminous is not clastic, as clastic refers to sedimentary rocks composed of fragments of pre-existing rocks. Bituminous, on the other hand, is a type of coal formed from the compression and heating of organic matter.
Organic, Chemical and Clastic
Clastic, Chemical, and Organic
Organic, Chemical and clastic.
Conglomerate is a clastic rock. They are coarse-grained sedimentary rocks.
Flint is a chemical sedimentary rock that forms from the precipitation of silica-rich fluids, rather than from the accumulation and compaction of organic or clastic sediment particles.
