Best Answer: The crust or lithosphere is the coolest layer by far. It is what we live on. It is in the vicinity of 0 degrees C (varying with depth and location). The mantle is about 1,700 miles (2,750 km) thick.
(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.
