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 … WebThe lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. ... Because of its relatively low density, continental lithosphere that arrives at a subduction zone cannot subduct much further than about 100 km (62 mi) before resurfacing. As a result, continental lithosphere is not recycled at ...
