(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.
The earth has four main layers which include the crust, the mantle, the inner core, and the outer core. The outer core of the earth is a liquid mix of elements, mostly iron and nickel, with smaller amounts of silicon and oxygen. It goes from a depth of 2550 km below the surface of the earth to 4750 km at the boundary of the inner core, during which time the temperature increases from 4500 to 5500 degrees Celsius.
