Why does the earth’s crust vary in thickness? Web21 de mai. de 2024 · How deep is the asthenosphere? This decreasing in seismic waves velocity from lithosphere to asthenosphere could be caused by the presence of a very small percentage of melt in the asthenosphere. The lower boundary of the LVZ lies at a depth of 180–220 km, whereas the base of the asthenosphere lies at a depth of about 700 km.
