Question

Quizplus · Accepted Answer

The asthenosphere is located between the lithosphere and the mesosphere, and it is where the upper mantle becomes more plastic or ductile. It extends from a depth of about 100 km to 700 km, and its thickness varies depending on the location and geological activity. Therefore, option B (100 km) is the best choice for the approximate depth of the asthenosphere.
