Coal is made from the remains of dead plants. It is made of carbon and other elements. Is coal a mineral?

Question

Yes, because it contains carbon.
No, because it is created artificially.
Yes, because it is formed naturally.
No, because it is an organic substance.

Answer 1

No, because it is an organic substance.

While coal is formed naturally and contains carbon, it is classified as an organic sedimentary rock rather than a mineral because it is derived from the remains of dead plants and contains organic material. Minerals are typically inorganic substances with a specific crystalline structure.
