How is oceanic crust different from continental crust (533 hits)
The Earth has three different layers to it.
The crust is the part of the Earth right on top where people live. The crust is subdivided into two types, oceanic and continental.
Oceanic crust
Oceanic crust is found under oceans, and it is about four miles thick in most places. A feature unique to oceanic crust is that there are areas known as mid-ocean ridges where oceanic crust is still being created. Magma shoots up through gaps in the ocean’s floor here. As it cools, it hardens into new rock, which forms brand new segments of oceanic crust. Since oceanic crust is heavier than continental crust, it is constantly sinking and moving under continental crust.
