WebFeb 13, 2024 · Lithosphere and asthenosphere are divisions based on mechanical properties: The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow. WebThe asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid.
