Difference between The Earth’s Lithosphere and 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. WebContrairement à la lithosphère, on pense que l'asthénosphère est beaucoup plus chaude, i. e. entre 300 et 500 degrés Celsius. Cela est dû au fait que l'asthénosphère est principalement solide avec certaines régions contenant des roches partiellement fondues.Ce qui contribue à ce que l'asthénosphère soit considérée comme visqueuse et … WebThe lithosphere and asthenosphere are typically recognized as two different zones on Earth. Lithosphere. The lithosphere is the hard outer layer of the Earth, reaching approximately 100 kilometers deep (62 miles).
