WebAnswer 1: Lithosphere refers to the rigid, rocky outer layer of the Earth. It comprises of the crust and the solid outermost layer of the upper mantle. Moreover, it extends to a depth of about 60 miles. It breaks up into around a dozen separate, rigid blocks, or plates. Question 2: Why is the lithosphere important? The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earths structure.
