(J. Louie). The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron (Fe) and is so hot that the outer core is molten, with about 10% sulphur (S).The inner core is under such extreme pressure that it remains solid.irculation and convection of electrically conductive molten iron in the Earth's outer core produces the magnetic field. To make the magnetic field, the convection must be relatively rapid (much faster than it is in the plastic mantle), so the core must be fluid.
Hot rock inside the Earth melts into a liquid called magma. Sometimes, currents in the magma push upward toward the surface, creating an underground fountain called a magma plume. Crust. The whole of the outside of the Earth is covered in a thin layer of cool, solid rock called the crust. Crust âº Mantle
