The lithosphere: Facts about Earth
Witryna16 kwi 2024 · The upper mantle is made up of lithosphere (sial and sima), asthenosphere (molten river rock), and mesophere. Describe the asthenosphere. The asthenosphere sits between mesophere and lithosphere. It is 700 km (430 mi) and is a plastic like layer. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere-asthenosphere boundary is conventionally taken … Zobacz więcej The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 … Zobacz więcej The asthenosphere extends from an upper boundary at approximately 80 to 200 km (50 to 120 miles) below the surface to a lower boundary at a depth of approximately 700 kilometers (430 mi).
