Depth of the lithosphere
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… WebJul 15, 2024 · Our planet ’s thin, 40-kilometer (25-mile) deep crust —just 1% of Earth ’s mass—contains all known life in the universe.
