- The asthenosphere is a portion of the upper mantle just below the lithosphere.
- The asthenosphere is between 100 to 200 km below the surface but can extend as deep as 700 km!
- The asthenosphere is the weakest, hottest, and deepest part of the upper mantle.
- The asthenosphere has very little density.
- The asthenosphere has a high temperature so it is like plastic.
