Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe… Web30 jan. 2024 · The depth of the MLD increases from about 83 km beneath the QLO to about 120 km beneath the margin of WNCC and TNCO and then decreases to about 93 km beneath the westernmost part of ENCC.
