What three structural zones overlap with the mantle?

The three structural zones that overlap with the mantle are the lithosphere, asthenosphere, and mesosphere. The lithosphere comprises the uppermost part of the mantle and the crust, while the asthenosphere is a semi-fluid layer beneath the lithosphere that facilitates tectonic plate movement. Below the asthenosphere lies the mesosphere, which is a more solid layer of the mantle extending down to the outer core. Together, these zones play a crucial role in Earth's geology and tectonics.
