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… WebHow dense is the lithosphere? Lithospheric Density. At about 50 kilometers (30 miles) below the Earth’s surface, density measurements reach 200,000 pounds per square inch (13,790 bars). Due to the pressure from the above crust and mantle, lithospheric density generally increases as both age of the surrounding rock and depth increase.
