Asthenosphere
The asthenosphere is part of earth's mantle. It is about 100 km to 350 km under the surface.[1] It is the lower part of the upper mantle, and behaves as a hot viscous liquid.
It consists of hot, weak material that can be deformed like silly putty. That means it is capable of gradual flow. It is under the lithosphere.
