WebApr 1, 2016 · The Oceanic lithosphere is denser than the continental lithosphere. Lithosphere is obviously thinner under the oceans and volcanically active continental regions than the other landmasses. The entire lithosphere is physically broken up into the brittle, moving plates containing the world’s continents and oceans. WebContinental lithosphere is composed approximately of a 20- to 35-mile layer of light granitic crust underlain by a 60- to 80-mile layer of heavy mantle peridotite (an olivine-, pyroxene-rich rock; Figure 5.1).Recall that these layers together form a tectonic plate.
