Denser and hotter than lithosphere above. under tremendous pressure and heat so that it is “soft”, near melting point, and flows plastically. -Lithosphere – less dense and cooler than asthenosphere. Which lithosphere is dense? The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure. Earth's inner structure can be described both chemically (crust, mantle, and core) and mechanically. The lithosphere–asthenosphere boundary lies between Earth's cooler, rigid lithosphere and the warmer, ductile asthenosphere. …
