The inner core, outer core, mantel and, finally the crust.
The mantle is roughly 1,802 miles thick and consists of four layers: the lithosphere, the asthenosphere, the upper mantle and the lower mantle. The layer closest to the surface of the Earth is the lithosphere, and the rock there is very similar to that of the crust. The layer closest to the core is the lower mantle, where the rock is the most dense and hotter than the rest of the mantle.
