Earth's upper mantle facts
WebThe asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak [1] 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). WebThe mantle has two main parts, the upper mantle and the lower mantle. The upper mantle is attached to the layer above it called the crust. Together the crust and the …
