Web-Earth's lithosphere is broken up into plates that float beneath the overlying mantle. The bottoms of the mantle's convection cells drag the tops of the plates, making them move. This movement causes spreading in some places and subduction in others. -Earth's lithosphere is broken up into plates that float on the underlying mantle. Web11 jan. 2024 · The definition of the lithosphere is based on how Earth materials behave, so it includes the crust and the uppermost mantle, which are both brittle. Since it is rigid and brittle, when stresses act on the lithosphere, it breaks. This is what we experience as an earthquake. Although we sometimes refer to Earth's plates as being plates of crust ...

A lithosphere (from Ancient Greek λίθος (líthos) 'rocky', and σφαίρα (sphaíra) 'sphere') is the rigid, outermost rocky shell of a terrestrial planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of up to thousands of years or more.
