The "earth's interior" is thought to be composed of magma and, at the core, molten iron and perhaps some nickel. If we look out on the crust of the earth, some 75-80% of the surface of our planet is composed of sedimentary rock. That leaves some 20-25% left to be composed of igneous and metamorphic rock.
