Question

Magma that cools very slowly deep beneath the surface forms minerals with what type of crystals?

Answer 1

igneous rock

Step-by-step explanation:

Extrusive or volcanic rocks crystallize from lava at the earth's surface. The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals.
