What does it mean for a mineral to have a definite (but not generally fixed) chemical composition?
- The chemical composition of a mineral is always the same
- The chemical composition of a mineral cannot be expressed by a specific chemical formula
- The chemical composition of a mineral is determined by laboratory techniques
- The chemical composition of a mineral can change over time (correct)

Study Notes
Characteristics of Minerals
- A mineral is a naturally occurring inorganic solid substance with a specific chemical composition and a crystalline structure.
- A mineral has a definite chemical composition, but it can vary slightly due to the presence of impurities or substitutions of elements.
- The ordered internal structure of a mineral refers to its crystalline arrangement, which is repeating and predictable, giving the mineral its unique properties.
- A mineral must be naturally occurring, meaning it is formed through geological processes, rather than being created artificially.
- In the context of minerals, an inorganic process is a natural process that does not involve living organisms, such as the formation of rocks through plate tectonics or the cooling of magma.
