Does Granite cools very quickly?
No. Granite cools relatively slowly; its large crystals are one method of observing this. Granite is referred to as a "phaneritic" igneous rock, meaning that it is coarse-grained. Coarse-grained rocks cool slowly, which means that the minerals have time to form large crystals before the rock solidifies. A rock with the same composition as granite that does cool quickly is called rhyolite.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
Granite and ryholite have similar composition but granite is course-grained whereas rhyolite is fine grained what is the difference?
Granite forms underground where magma cools slowly, allowing relatively large crystals to form. Rhyolite forms above ground as lava cools quickly, meaning that any crystals will be small.
