The upper mantle is liquid rock, and very hot. WitrynaThe asthenosphere lies below the lithosphere, from about 100-200 km to about 670 km deep. It includes the more “plastic” softer region of the mantle, where fluid movements can occur. The solid lithosphere is thus floating on the fluid asthenosphere.
