WebThe asthenosphere is thicker than the lithosphere, making it a relatively small mantlepiece. The lithosphere is very rigid and very hard to deform. The asthenosphere is fairly easy to deform. It works like toffee. If you squash toffee, change its shape and deform it, and that’s called plastic deformation. http://www.differencebetween.net/science/differences-between-the-earths-lithosphere-and-asthenosphere/
