a mineral crystallizes from magma deep inside earth. which characteristics can be determined given only the…

Answer:

crystal size

Explanation:

Step1: Analyze luster

Luster depends on surface - light interaction, not just formation source.

Step2: Analyze streak

Streak is about color of powdered mineral, not determined by magma - origin alone.

Step3: Analyze crystal size

Minerals crystallizing deep in Earth from magma have slow - cooling conditions. Slow cooling allows larger crystals to form. So crystal size can be inferred.

Step4: Analyze crystal structure

Crystal structure is related to chemical composition and internal atomic arrangement, not directly from magma - origin information.
