usgs_asthenosphere.gif The Asthenosphere is a region within a layer of the Earth's mass, known as the mantle. It is below the surface between 100 and 200 kilometers. Some scientists believe that the Asthenosphere can go as deep as 400 kilometers. It rests directly underneath the lithosphere and within the upper mantle. In this class we conducted a lab experiment. We used some corn starch and mixed it with water and played with it. If your bored one day and have the materials to do it, I suggest you do so. All you need is about a handful of corn starch mixed with half a cup of water. The corn starch acts as almost a liquid but at the same time a solid, it moves as the Asthenosphere does. At the same time it teaches about matter, so in this experiment you learn about two things for the price of one.
