Lithosphere starting depth
Web30 mrt. 2024 · The viscosity value to be used is the mantle value such as m 2 /s based on inferences from the sinking speed of subducted lithosphere (Čížková et al., 2012). The speed is the approximate speed for plates 3 × 10 −10 m/s, and d corresponds to the mantle depth d = 3 × 10 6 m (whole mantle convection). Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe…
