Ranges of brittle and viscosity characteristics of crust, near the surface, and a part of the upper mantle below, determine the thickness of lithosphere. ,


Including parts of upper mantle, the viscosity and brittle

characteristics determine the depth of lithosphere, from the surface.

Under the ocean, lithosphere might extend up to about 100 km.

Continental lithosphere might be up to 200 km.

The mechanically rigid or sedimentary outer layer of lithosphere

might be broken into tectonic plates, (formed under pressure), with

convergent, transforming and divergent boundaries.
