WebOceanic lithosphere thickens as it ages and moves away from the mid-ocean ridge. This thickening occurs by conductive cooling, which converts hot asthenosphere into lithospheric mantle, and causes the oceanic lithosphere to become increasingly dense with age. Oceanic lithosphere is less dense than asthenosphere for a few tens of millions of ...

What is Lithosphere? Lithosphere Composition
WebThe lithosphere is the outermost layer of the Earth’s surface. It is rugged, dense, and mostly made out of solid rock. Generally speaking, Earth is made of a really hot core and layers of rock that get colder the farther you move from the center. The lithosphere is the farthest layer from the core and so is the coldest, made of mostly solid rock. Weboceanic crust, the outermost layer of Earth’s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment. crna program oakland university
