WebPlate tectonics refers to the movement of the rigid plates around the surface of Earth. The outer portion of the planet, or lithosphere, is relatively rigid because it is relatively cold. The lithosphere varies in thickness but is typically a hundred or so kilometers thick. It includes the upper mantle and both the continental and oceanic crust. WebJul 15, 2024 · “ Crust ” describes the outermost shell of a terrestrial planet. Our planet ’s thin, 40-kilometer (25-mile) deep crust —just 1% of Earth ’s mass—contains all known life in the universe. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.
