Quizplus · Accepted Answer

The thickness of Earth's crust varies significantly between the oceanic and continental crust. Under the oceans, the crust is thinner, averaging about 5 km in thickness, while under the continents, it can be much thicker, up to about 70 km. This variation is due to the different compositions and processes that form these types of crust.
