Igneous rocks are of two types intrusive plutonic rocks and extrusive volcanic rocks.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
Granite is an example of igneous rock that forms deep beneath earthвђ s surface.
Intrusive igneous rocks are formed when the magma cools off slowly under the earth s crust and hardens into rocks.
Igneous rocks are formed from the solidification of molten rock material.
Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

Formed by fire examples.
Igneous rock derived from the latin word ignis meaning fire or magmatic rock is one of the three main rock types the others being sedimentary and metamorphic igneous rock is formed through the cooling and solidification of magma or lava the magma can be derived from partial melts of existing rocks in either a planet s mantle or crust typically the melting is caused by one or more of.
