WebA lithosphere (from Ancient Greek λίθος (líthos) 'rocky', and σφαίρα (sphaíra) 'sphere') is the rigid, [1] 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.
WebThe lithospheric plates are composed of the rocky crust and outermost rocky layer of the mantle which are fused together. The entire outer surface of the planet is divided into these plate formations, roughly 30 in total, which vary in size from over100,000,000 square miles (Pacific Plate) to the Galapagos microplate at 12,000 square miles.

Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica. The composition is important because it makes continental crust less dense than ocean crust. first world fall through
