Continental crust is also less dense than oceanic crust, whose density is about 2.9 g/cm 3. At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7â10 km. About 40% of Earth's surface is currently occupied by continental crust. It makes up about 70% of the volume of Earth's crust.
