Asthenosphere. Introduction. The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. The rocks are less dense than the rocks in the lithosphere.
Rocks in the lithosphere are rigid, meaning that they can bend but they cannot flow. Rocks in the asthenosphere are plastic, meaning that they can flow in response to deformation. Even though it can flow, the asthenosphere is still made of solid (not liquid) rock; you can think of it kind of like Silly Putty.
