The crust is floating on a sea of liquid 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. … WebThe crust includes a lot of granitic/siliceous rocks, which are less dense than the mafic, oceanic basalts, and oceanic basalt is closest to the composition of the mantle. The continents essentially are kind of ‘floaty’ (lighter weight/mass, therefore riding higher) compared to the ocean crust. Sponsored by The Penny Hoarder
