Web30 de mar. de 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). imx250 sony

The entire mantle is about 1800 miles thick, which means the lower mantle makes up the bulk of this part of the Earth. The temperature of the mantle near the crust ranges from 900 to 1600 degrees Fahrenheit. It gets hotter at greater depths. Web22 de jul. de 2024 · The mantle has a density of 4.5 g/cm3 and temperatures in the range of 1000-1500 oC. The uppermost layer of the mantle is more rigid while the deeper regions are fluid and it is the motion of fluid materials in the mantle that is responsible for plate tectonics (see section 4.3).
