Description of the asthenosphere
WebSep 11, 2013 · Asthenosphere. Beneath the lithosphere is a relatively weak and ductile layer of the mantle called the asthenosphere. Although the asthenosphere is solid, not liquid, it flows at geological rates, up to several cm (several inches) per year. In other words, the asthenosphere behaves much more plastically than the rigid lithosphere above it does. WebAsthenosphere. The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere. Summary. The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere ...
