Lithosphere:

Lithosphere, rigid, rocky outer layer of Earth , consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). The lithosphere is broken up into about a dozen separate, rigid blocks, or plates. Lithosphere is the rigid, outermost rocky shell of a terrestrial planet or natural satellite, composed of the crust and the lithospheric mantle. Learn about the concept, the types (oceanic and continental), and the history of the lithosphere on Earth. Learn about the lithosphere , the outermost solid layer of the Earth, and its two types: oceanic and continental. Find out how it is composed of crust and mantle, and how it moves due to plate tectonics. Learn about the lithosphere , the outermost hard layer of the Earth, composed of the crust and the uppermost mantle. Explore its types, layers, components, properties and its relationship with other spheres of life.
