Lithosphere And The Asthenosphere Worksheet Essay Project ... Beneath the lithospheric plates lies the ASTHENOSPHERE, a layer of the mantle composed of denser semisolid rock. Because the plates are less dense than the asthenosphere beneath them, they are floating on top of the asthenosphere. Deep within the asthenosphere the pressure and temperature are so high that the rock can soften and partly melt.
