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… Web1 mei 2010 · In 1988, Babuška & Plomerová compiled a map of European lithosphere thickness, mainly from P residual studies. They mapped thick lithosphere (>200 km) beneath the southwestern margin of the East European Platform, beneath two zones in the eastern and western Alps, and beneath a narrow zone in the East Carpathians.
