Final answer:

Continental crust is denser than oceanic crust due to their different compositions. Oceanic crust consists of basalt, which is more dense, while continental crust is predominantly made up of granite, which is less dense.

Step-by-step explanation:

Continental crust is more dense than oceanic crust due to their different compositions. Oceanic crust is composed of basalt, which is a mafic rock with a higher density. On the other hand, continental crust is made up of granite, which is less dense. The average density of oceanic crust is about 3 g/cm³, while the density of continental crust is also about 3 g/cm³.
