Lithosphere and asthenosphere location
WebLithosphere and asthenosphere are divisions based on mechanical properties. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow. Web2 apr. 2024 · The boundary between the lithosphere and asthenosphere can be defined in several ways: mechanically, thermally, rheologically, compositionally, and finally seismically. All are approximations for something humans will never be able to access directly. Wikipedia has this to say about the seismic definition:
