Answer
Continental crust is generally older than oceanic crust
Explanation
The average density of the continental crust is lower (2.6 g/cm3) than the oceanic crust(3.0 g/cm3). This allows the continental crust to float on the upper mantle. The rocks in the oceanic crust are younger than those in the continental crust. The continental crust is thicker( 35-70km) than the oceanic crust(5-10 km).
