'''Igneous rocks''' are formed when molten [[rock]] is either ejected directly on to the earth's surface ([[extrusive rock]]) or pushed up near the surface and cools beneath it ([[intrusive rock]]). Molten rock beneath the earth's crust is called [[magma]]; when magma is ejected throught the crust it is called [[lava]].
