Web30 Mar 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). WebThe highest temperature of the upper mantle is 900 °C (1,650 °F). What is the difference between upper and lower mantle? There are very small differences between the two layers. The upper mantle has Olivine (a very special rock), compounds with silicon dioxide, and a substance called Peridotite. The lower mantle is more solid than the upper mantle.
