What are the mechanical layers of Earth?

The compositional layers are the crust, the mantle and the core. When we look at the mechanical properties of the layers, we are defining them as the mechanical layers. The five mechanical layers are the lithosphere, the asthenosphere , the mesosphere, the inner core and the outer core.
