Granite and basalt are both igneous rocks. Why are the mineral grains so much larger in granite than basalt?
Granite is formed from magma which cools and hardens slowly allowing for larger crystal formation. Basalt is formed from lava which cools and hardens very quickly since it is exposed to the cool surface of the earth.
