It permits plate motion

Further Explanation:

The asthenosphere is highly viscous and the part of the upper mantle of the earth just below the lithosphere and asthenosphere is a mechanically weak and soft region that is present on the upper layer of the Earth. Asthenosphere lies just below the lithosphere and its depth is approximately 80 and 200 kilometers below the surface. It is solid in nature but some of its regions are molten in nature.

The temperature is the asthenosphere depends on its thickness and its rheology is dependent on the rate of deformation and that means that the asthenosphere could also be formed because of the result of a high rate of deformation. In some regions of the earth, the asthenosphere could extend as deep as 700 km and it is considered as the source region of the mid-ocean ridge basalt.
