What Is the Difference Between Lithosphere and Asthenosphere?

Web5 apr. 2024 · This difference in relative density causes oceanic plates to subduct beneath the more buoyant continental plates. This also allows the denser oceanic plates to sink further into the fluid asthenosphere, causing them to lie below sea level. In contrast, the more buoyant continental plates float higher, resulting in dry land.
