Web1 jan. 2012 · Estimates of the maximum thickness of the continental thermal lithosphere range anywhere between <200 and >300 km (e.g. Jordan 1975; Rudnick et al. 1998; Artemieva & Mooney 2001; Gung et al. 2003, Yuan & Romanowicz 2010) and vary strongly as a function of tectonic province. • Geology portal • Asthenosphere – Highly viscous, mechanically weak, and ductile region of Earth's mantle • Continent – Large geographical region identified by convention • Craton – Old and stable part of the continental lithosphere

WebThe asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. crustal generation and destruction Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move. The cool, brittle lithosphere is just one of five great spheres that shape the environment of Earth. The other spheres are the biosphere (Earths living things); the cryosphere (Earths frozen regions, including both ice and frozen soil); the hydrosphere (Earths liquid water); and the atmosphere … Meer weergeven The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earths structure. It is bounded by the atmosphere above … Meer weergeven There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated … Meer weergeven Most tectonic activity takes place at the boundaries of these plates, where they may collide, tear apart, or slide against each other.
