WebThe asthenosphere is the zone of the earth which lies beneath the lithosphere. It is said to be hotter and more fluid than the lithosphere. We can say it extends from around 100 km to around 700 km beneath the surface of the earth. The rocks found in this zone which are mostly peridotite are quite solid in structure. The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 mi) below the surface, and extends as deep as 700 km (430 mi). However, the lower boundary of the asthenosphere is not well defined.
