When exposed by erosion, these cores (called batholiths) may occupy huge areas of the Earth's surface.

Intrusive igneous rocks that form at depth within the crust are termed plutonic (or abyssal) rocks and are usually coarse-grained.

Intrusive rocks can also be classified according to the shape and size of the intrusive body and its relation to the other formations into which it intrudes.

The central cores of major mountain ranges consist of intrusive igneous rocks, usually granite.Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.Extrusive igneous rocks cool and solidify quicker than intrusive igneous rocks.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.
