Lithosphere

Lithosphere \Lith"o*sphere\, n. [Litho- + sphere.] (Phys. Geog.)

  1. The solid earth as distinguished from its fluid envelopes, the hydrosphere and atmosphere.

  2. 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.

Wikipedia
Lithosphere

A lithosphere ( [lithos] for "rocky", and [sphaira] for "sphere") is the rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. The outermost shell of a rocky planet, the crust, is defined on the basis of its chemistry and mineralogy.

Lithosphere (album)

Usage examples of "lithosphere".

When it reached the solid part of the lithosphere, the ac­tual Clyde craton, which was about 35 kloms thick, it was still hot enough to melt the rock in its path and turn it into the stuff called kimberlite.

If so, why shouldn’t the same 30° one-piece shift of the lithosphere have swivelled a largely deglaciated six-million-square-mile southern hemisphere continent from temperate latitudes to a position directly over the southern pole of the spin axis?

Above the curve of the lithosphere, which was opaque and black, lay—in the same bent band—a whitish mist, thickest along the horizon: the atmosphere, with microscopic floccules that were clouds.

It was as if the planet itself had felt something missing, and at the tap of mind against rock, noosphere against lithosphere, the absent biosphere had sprung into the gap with the startling suddenness of a magician's paper flower.
