How is granite formed?
Granite is an igneous rock. Magma from deep within the earth travelled upwards towards the crust. As it got closer to the crust the temperature dropped and it cooled slowly, forming rock with big crystals.

Basalt is an igneous rock. A volcano erupted and produced lava which cooled quickly on the Earth's surface, creating rock with small crystals.
