Igneous rocks are formed from magma from the process of crystallization. There are two ways to classify igneous rock: intrusive (in) and extrusive (out).

Intrusive, also known as plutonic rocks.

-crystallizes below earth's surface

-found inside the volcano

-forms into large crystals

Extrusive, also known as volcanic rocks.
