Coal is a very useful rock that formed over millions of years from the remains of plants. Is coal a mineral
As an AI language model, I can tell you that while coal is often referred to as a mineral, it is technically not a true mineral.
Minerals are naturally occurring, inorganic substances with a specific chemical composition and crystalline structure. Coal, on the other hand, is an organic substance that is comprised mainly of carbon, hydrogen, and oxygen. It does not have a specific chemical composition or crystal structure and is formed through a different process than that of minerals.
However, coal is often classified along with minerals because it is a naturally occurring resource that is extracted from the ground and is important for industrial and energy purposes.
