Lithosphere geology definition

The outer portion of the Earth is divided into an upper, lithosphere layer and a lower, asthenosphere layer. The lithosphere layer is composed of two parts, an upper, the crustal lithosphere and lower, the mantle lithosphere. The crustal lithosphere is in unstable mechanical equilibrium because the underlying mantle lithosphere has a greater density than the asthenosphere below. The difference in densities can be explained by thermal expansion/contraction, composition, and phase chang… WebThe lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid.
