Answer:
1)Oceanic crust have high density than continental crust.
2)Oceanic crust is thinner while Continental crust is thick.
3)Oceanic crust has composition of Basalt rock which are made up of rocks rich in minerals like silicon, oxygen, and magnesium. while Continental crust is made up of granite rocks and this rocks contains aluminium-silicon and oxygen.
4)Oceanic crust rock is sima a short form of magnesium silicates which are the main components that make up Oceanic crust while Continental crust is called sial because its bulk composition is richer in aluminium silicates which are main constituents.
5)Continental crust floats on magma freely but oceanic crust floats on magma scarcely.
6)Continental crust cannot recycle whereas oceanic crust can recycle it
