These plates lie on top of a … Web23 sep. 2024 · A key requirement for plate tectonics is that there is limited resistive drag for lithospheric plates to move over the asthenospheric mantle ().Yet, imaging and understanding the mechanical nature of the lithosphere-asthenosphere boundary (LAB) has been a long-standing challenge to seismology ().The LAB was viewed as a …
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).
