Lith"o*sphere (?), n. [Litho- +
sphere.] (Phys. Geog.) (a) The
solid earth as distinguished from its fluid envelopes, the hydrosphere
and atmosphere. (b) The outer part of the
solid earth, the portion undergoing change through the gradual
transfer of material by volcanic eruption, the circulation of
underground water, and the process of erosion and deposition. It is,
therefore, regarded as a third mobile envelope comparable with the
hydrosphere and atmosphere.
