Explanation:

The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure.

The asthenosphere is the highly viscous, mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km below the surface.

In geology, sima is an antiquated blended term for the lower layer of Earth's crust. This layer is made of rocks rich in magnesium silicate minerals. ... Comparable is the name 'sial' which is the name for the upper layer of Earth's crust (continental crust).
