What is the difference between oceanic and continental crust?

• The ocean crust is thicker and less dense

• The continental crust is thicker and more dense

• The oceanic crust is thinner but more dense

• The continental crust is thinner and less dense

Answer explanation

The oceanic crust is thinner (about 5-10 km) but denser (3.0 g/cm³) compared to the continental crust, which is thicker (up to 70 km) and less dense (2.7 g/cm³). Thus, the correct choice is that the oceanic crust is thinner but more dense.
