Which is a factor that affects the size of mineral crystals formed in magma?
a. rate of cooling
b. fluorescence
c. evaporation
d. elements dissolved in hot water

Option (a) is the correct answer.

Explanation:

On cooling, magma forms crystals as the solution gets very saturated as compared to other minerals. When magma cools slowly, the crystals get enough time to grow and as a result they become large in size.

Whereas when magma cools quickly, then the crystals did not get enough time to grow as a result they remain are very small in size.

Thus, we can conclude that rate of cooling affects the size of mineral crystals formed in magma.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
