Asthenosphere is a dense and weak layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) below the surface. The temperature and pressure in the asthenosphere are so high that the rock softens and partially melts into a semi-molten state.
