Question

BIg crystals are formed when a hot saturated solution is cooled, why?

Answer 1

Because when magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time toform, so they are very small. If the magma cools slowly, then the crystalshave enough time to grow and becomelarge.
