This is why the lithosphere is further divided into subspheres namely the crust, the mantle, the outer core, and the inner core. The crust is made of loose soil and rocks. The mantle is made of dense rock made up of nickel and iron in the form of silie rocks and its lower part is semisolid (partially molten) rocks.
