Volcanic and plutonic rocks are types of igneous rock. Volcanic rocks form when lava cools and solidifies on earth and plutonic rocks form when magma cools and solidifies below earth.Learn about different characteristics of these igneous rocks.olcanic rocks are also known as 'extrusive igneous rocks.'
