Question

what determines a minerals unique characteristics?
o age and location where its found
o chemical composition and crystal structure
o color and temperature resistance
o size and weight of the sample

Explanation:

The chemical composition determines the elements present in a mineral, and the crystal structure dictates the arrangement of atoms. Together, they give a mineral its unique physical and chemical properties. Age and location affect where it's found but not its inherent characteristics. Color can be variable and temperature - resistance is a secondary property. Size and weight of a sample are not defining features of a mineral's uniqueness.

Answer:

B. Chemical composition and crystal structure
