Lithosphere. A 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 lithospheric mantle, the topmost portion of the upper mantle that behaves elastically on time scales ...

We know the lithosphere exists because it's where we live and we can see the direct effects of plate tectonics through spectacular volcanoes and lofty mountain ranges. But how do we know what's going on below the surface? Earthquakes and seismic waves can tell us a lot about the Earth's interior, including where the lithosphere and asthenosphere ar...

Nov 29, 2023 · The lithosphere has two layers: the crust and the rigid or brittle upper part of the mantle. Geologists call this upper part of the mantle a lithospheric or lithosphere mantle. Besides layers, the lithosphere is either oceanic or continental. Oceanic one occurs on the ocean or seafloor and continental on continents.

Apr 25, 2024 · Subjects. “ Crust ” describes the outermost shell of a terrestrial planet. Our planet ’s thin, 40-kilometer (25-mile) deep crust—just 1 percent 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.
