Lithosphere
- The lithosphere is the rigid outermost shell of a rocky planet.
- On Earth, the lithosphere is a portion of the crust and the upper mantle.
- The lithosphere is broken into tectonic plates.
- The lithosphere is on top of the asthenosphere.
- The oceanic lithosphere is approximately 50 to 100 km thick.
- The continental lithosphere is approximately 40 to 200 km thick.
- The oceanic lithosphere is denser then the continental lithosphere.
- Studies show that large parts of the lithosphere have been taken away into the mantle as deep as 2,900 km near the boundary between the core and the mantle!
