== == Coal is very close to being a mineral but since it is organic (made from remains and organic substances) it does not qualify.
Glass is not a true mineral. Although it is solid and formed in nature, it does not have a consistent chemical composition or crystal structure, which are defining characteristics of minerals.
Sulfur is a common mineral found in coal. Its presence in coal can lead to sulfur dioxide emissions when the coal is burned, contributing to air pollution.
Wood is a nonmetallic mineral resource. Coal, iron, and aggregate are metallic mineral resources.
Coal belongs to the mineral group called organic minerals because it is primarily made up of organic matter, mainly carbon along with small amounts of other elements.
Coal is classified as an organic sedimentary rock. It is primarily composed of carbon-containing compounds formed from plant material that has been preserved over millions of years through geological processes.
No, it is not because it is organic.
Glass is not a true mineral. Although it is solid and formed in nature, it does not have a consistent chemical composition or crystal structure, which are defining characteristics of minerals.
Coal is not a mineral. A mineral is a solid non-organic substance. Coal is an organic substance.
Coal is not a mineral and is not rare.
Pennsylvania's most important mineral is coal. Second is oil.

No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
A mineral must have a definite chemical composition and a crystalline structure, neither of which apply to coal.
