Difference Between Lithosphere and Asthenosphere
WebBehaviorally, the outer earth layers are divided into the lithosphere and asthenosphere (see right side of enlarged drawing ). The lithosphere is the cold, rigid outer layers, and is composed of the crust and the outermost portion of the mantle. The underlying asthenosphere is all ultramafic mantle, but it is hot and plastic.

A zone of … The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 mi) below the surface, and extends as deep as 700 km (430 mi).
