Answer;
- Formed from once-living material
A mineral cannot be formed from once-living material.
Step-by-step explanation;
-A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.
-Therefore, for a substance to be considered a mineral it should be;
- naturally occurring
- inorganic
- solid
- definite chemical composition
- ordered internal structure
-Naturally occurring means that people did not make it. Definite chemical composition means that all occurrences of that mineral have a chemical composition that varies within a specific limited range. Ordered internal structure means that the atoms in a mineral are arranged in a systematic and repeating pattern.
