Question

Quizplus · Accepted Answer

The continental crust is mostly composed of granitic rocks and is less dense than the oceanic crust which is mostly composed of basaltic rocks. As a result, the continental crust tends to be more buoyant and less likely to be subducted beneath the oceanic crust. This means that the continental crust tends to persist for longer periods of time and thus most of the continental crust is older than the oceanic crust.
