The asthenosphere is the highly viscous, mechanically weak and ductilely
deforming region of ... The thickness of the asthenosphere depends mainly on
the temperature. In some regions the asthenosphe...
The asthenosphere has no exact size, but the United States Geological Survey
estimates it is approximately 111.85 miles (180 kilometers) thick. It is highly ...
The asthenosphere is the ductile part of the earth just below the lithosphere,

upper mantle, 100 to 200 kilometers below surface, is called the asthenosphere.
Continental crust is variable in thickness and composition. ... The upper and
lower boundaries of the asthenosphere are diffuse as they involve gradual
