What is the definition of a mineral?

• A. A naturally occurring organic compound
• B. A synthetically created solid material
• C. A naturally occurring inorganic solid material with an orderly crystalline structure
• D. A liquid substance that possesses crystalline properties

Answer: (C)

A mineral is defined specifically as a naturally occurring inorganic solid material that has an orderly crystalline structure. This definition emphasizes the natural origin of minerals, distinguishing them from synthetic compounds that are created by human processes. Moreover, the requirement for an orderly crystalline structure indicates that the atoms in a mineral are arranged in a highly organized and repeating pattern, which is a key characteristic that differentiates minerals from other substances. In contrast, choices that suggest organic origins or synthetic creation do not align with the established definition of minerals. The notion of a liquid substance having crystalline properties also conflicts with the definition, as minerals must be solid; liquids do not possess a fixed shape or crystalline structure. Thus, the correct answer captures the essence of what defines a mineral in Earth Science.
