2. "There are three different kinds of crust" – False, there are two main types: continental and oceanic.
3. "The crust is thickest under the ocean" – False, continental crust (thickness ~30 - 70 km) is thicker than oceanic crust (~5 - 10 km).
4. "The ocean crust is made of young rocks" – True, oceanic crust is formed at mid - ocean ridges and is relatively young (recycled more often).
5. "The ocean crust is denser than continental crust" – True, oceanic crust (basalt - rich) is denser than continental crust (granite - rich).
