Question

Molten materials cool at different rates. Which property of a mineral does this affect?
color
luster
crystal size
crystal shape

Answer 1

Explanation:

The answer to this question is; Crystal size. When lava spews to the earth's surface, volcanic rocks crystallise as a result of the cooling. The rate of cooling decides whether the igneous rocks thus formed are fine-grained or coarse-grained (texture). When the cooling is gradual, large crystals form.
