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. WebThe asthenosphere is the layer below the lithosphere. Astheno- means lacking strength, and the most distinctive property of the asthenosphere is movement. Because it is mechanically weak, this layer moves and flows due to convection currents created by …

WebThe Earth’s asthenosphere is also made up of reasonably solid peridotites. About 99% of the asthenosphere is solid rock, and the other 1% is a molten-like magma state. The asthenosphere is hot, and that heat makes it mechanically weak compared to the lithosphere.
