False. When lava cools quickly, it typically forms small crystals or an amorphous glass due to the rapid solidification, which doesn't allow large crystals to develop. Large crystals usually form from slower cooling processes, such as in magma that cools underground.
False.
True
Yes. And the size of crystals depend on the time taken to crystallize.
It becomes true negative.
