Lithosphere is the rigid- rocky outer layer of the earth- consisting of the crust and the solid outermost layer of the upper mantle- It extends to a depth of about 100 km- It is broken into about a dozen separate- rigid blocks- or plates- The lithosphere is underlain by the asthenosphere which is the weaker- hotter- and deeper part of the upper mantle-
