WebContinental crust floats higher in the mantle than ocean crust because of the lower density of continental crust. ... Asthenosphere. Beneath the lithosphere is the … 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/cm3, and a viscosity of 1022 poise, while the latter has a density of 3.23 g/cm3, a viscosity in the range 1021-1018–19 poise, and a temperature …

WebAnswer: If you could see the cross section of the Earth, you would see four distinct layers - the outer crust, the mantle, the outer core and the inner core. The layer of crust is very … WebLithosphere. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is about 100 kilometers thick.

WebAnd so we call this process, this is convection. Now, the reason why we think the plates are moving is because we think that there are similar types of convection currents in the asthenosphere, in the mantle, in the more fluid part of the mantle. Remember, most of the mantle you can kind of view it as this mooshy, spongy, not quite liquid, but ... Webasthenosphere. asthenosphere ăsthēn´əsfēr [ key], region in the upper mantle of the earth's interior, characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere. The upper part of the asthenosphere is believed to be the zone upon which the great rigid and brittle ...
