The Earth's outermost layer is the crust. However, not all crust is the same. Oceanic crust differs from continental
One such way is that oceanic crust is younger than continental crust. Which statement best explains why this is so?
O The chemical compositions are different, and that which makes up oceanic crust has a more recent geological history.
Oceanic crust is thinner than continental crust, which means it has not had as much time to build up as continental crust.
Oceanic crust is continuously recycled with mantle material during the mantle upwelling and downwelling process, and this
process is virtually non-existent for continental crust.
Oceanic crust is denser than continental crust, and density is associated with age in geological features.
