Two types of igneous rocks are intrusive which is found in a volcano. And extrusive which is found outside of a volcano.
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
Two types: Extrusive igneous rock and Intrusive igneous rock.
Pumice is ground up to form an abrasive. Obsidian was used by indians to make arrow heads.
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
Basalt and rhyolite are examples of fine-grained igneous rocks.

Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
