What is the relatively soft layer of rock below the lithosphere? The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heatinâ¦g and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
