Temp of the asthenosphere
WebBasic Facts about the Asthenosphere. ♦ The asthenosphere is composed of matter in the molten or semi-molten state. Its temperature is normally between 1,400 degree Celsius to 3,000 degree Celsius. The very high … WebWe define the asthenosphere viscosity as the lowest viscosity in the upper mantle in a specific region. Generally, the temperature profile is the dominant variable to define regional viscosity. We approximate the mantle temperature profile as adiabatic with a thermal boundary layer at the top.
