Also Lithosphere is bounded by the atmosphere from above and the asthenosphere from below. Question: Difference between crust and lithosphere. Answer:
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. WebL'asthénosphère représente la partie la plus ductile, la plus faible d'un point de vue mécanique, du manteau terrestre.
