How many miles thick is the asthenosphere
Web11 jan. 2024 · The lithosphere is about 100 kilometers thick. How are crust and lithosphere different from each other? The definition of the lithosphere is based on how Earth materials behave, so it includes the crust and the uppermost mantle, which are both brittle. Since it is rigid and brittle, when stresses act on the lithosphere, it breaks. WebThis strong outer layer is called the lithosphere, which is 100 km (60 miles) thick. The lithosphere includes the crust and upper mantle. Below the lithosphere is the asthenosphere, which is a plastic like layer that allow the lithosphere to move around due to its convection currents.
