Does Basalt cool quickly or slowly?
Basalt is extrusive. The magma from which it cools breaks through the crust of the earth and erupts on the surface. … Because the magma comes out of the earth (and often into water) it cools very quickly, and the minerals have very little opportunity to grow.
What is the size of the crystals if the rock cools slowly and forms below the earths surface?
If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large. Some granites contain minerals which are up to one meter (3 ft) across!
