Answer:
A naturally occurring, inorganic solid with an orderly crystalline structure and a definite chemical composition is a mineral.
Explanation:
The word mineral is used in different ways, one of them being when referring to any valuable material extracted from the Earth, like coal for example. By definition, a mineral is a naturally occurring (as they are form by geological processes that are not human-controlled or affected), inorganic solid (that's is to say something that it is not animal or plant and that is not in the form of liquid or gas), with an orderly crystalline structure (atoms are arranged in an organized and repetitive pattern) and a definite chemical composition (although the chemical composition of minerals is always definite, it can vary within some specific limits and types of minerals).
