Wikipedia
Asthenosphere
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. The asthenosphere is almost solid, but a slight amount of melting (less than 0.1% of the rock) contributes to its mechanical weakness. More extensive decompression melting of the asthenosphere takes place where it wells upwards, and this is the most important source of magma on Earth. It is the source of mid-ocean ridge basalt (MORB) and of some magmas that erupted above subduction zones or in regions of continental rifting.

asthenosphere
The asthenosphere is the highly viscous, semi-fluid, mechanically weak, and ductile layer of the upper mantle of the Earth. It lies beneath the lithosphere, at depths between approximately 80 km and 200 km below the Earth's surface. The asthenosphere is composed mostly of silicate rocks and is involved in tectonic plate movements, contributing to plate tectonics and volcanic activity.

The asthenosphere is the highly viscous, mechanically weak and ductilely-deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between 100 and 200 km below the surface, but perhaps extending as deep as 700 km. It is considered the source region of mid-ocean ridge basalt.
