Web29 nov. 2024 · The lower mantle temperature, in contrast, reaches over 7,230 degrees Fahrenheit or 4,000 degrees Celsius. Pressure is one great difference between the upper and lower mantle. The viscosity of the upper mantle is greater than the viscosity of the lower mantle. This is because there is less pressure at the upper mantle. Web1 aug. 1993 · Under the northern margin of the Otway basin in southeastern Australia, the Moho depth of 31 km and the upper-mantle velocity of 7.8 km/s interpreted from seismic data are in good agreement with laboratory measurements reported by other workers on spinel Iherzolites in xenoliths from this same area; the laboratory data give an average P …
