Web15 sep. 2024 · The continental lithosphere is composed of a 40-km-thick crust (a 20-km-thick upper crust and a 20-km-thick lower crust) and a 110-km-thick mantle. The lithosphere-asthenosphere boundary (LAB) is determined by the intersection of the geotherm (black) with the mantle adiabat (red). 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…
