Question

As the rate of cooling of igneous rocks increases, the size of the crystals that form

Answer 1

As the rate of cooling of igneous rocks increases, the size of the crystals that form decrease. Sense the size of the crystals will decrease, this would include that the rate of cooling of igneous rocks increases.

Answer 2

Answer:

The correct answer is "decreases".

Explanation:

As the rate of cooling of igneous rocks increases, the size of the crystals that form decreases. Volcanic or igneous rocks go trough a cooling process when they reach the Earth's surface, crystallizing and forming different crystal forms. The size of the crystals depend on the cooling rate, slow cooling allow the formation of large crystals, while fast cooling yields small crystals.
