Lithosphere vs asthenosphere density

WebThe lithosphere and asthenosphere make up a common geodynamic system but are characterized by different physical parameters. The former has a temperature of 1200–1300°C, a density of 3.3 g/cm 3, and a viscosity of 10 22 poise, while the latter has a density of 3.23 g/cm 3, a viscosity in the range 10 21 -10 18–19 poise, and a … WebThe asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak [1] and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 mi) below the surface, and extends as deep as 700 km (430 mi).

Mantle. Core. Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal. Webasthenosphere . The lithosphere consists of the crust and the cool, rigid, outer 80-100 km of the mantle . The crust and outer mantle moves together as a unit, so they are combined together into the lithosphere. The asthenosphere lies below the lithosphere, from about 100-200 km to about 670 km deep. hifi repairs brisbane
