Web29 nov. 2024 · The lithosphere essentially glides over the asthenosphere as a series of tectonic plates. The depth of the upper mantle ranges between 250 to 410 miles (403 to 660 km). At this depth, rock can liquefy into magma. Magma then rises due to convection, and as it spreads it forms the ocean floor’s crust. Web30 jan. 2024 · In the pre-plate tectonics era, Daly (1940) inferred that the outer Earth consisted of three spherical layers: lithosphere (including the crust), asthenosphere, and mesospheric shell. Daly’s hypothetical depths to the lithosphere–asthenosphere boundary ranged from 80 to 100 km (50 to 62 mi), and the top of the mesospheric shell (base of …
