Question

Quizplus · Accepted Answer

Oceanic crust is more dense and thinner than continental crust. This is because oceanic crust is primarily made up of basaltic rocks, which are denser than the granitic rocks that make up continental crust. Additionally, oceanic crust is constantly being formed at mid-ocean ridges and then pushed away from the ridge by plate tectonic forces, causing it to be thinner than the more stable continental crust.
