* On the surface: It forms the land we walk on, the mountains, and the valleys.
* Continents: It makes up the continents, which are the large landmasses separated by oceans.
* Under the oceans: While most of the continental crust is above sea level, some of it extends below sea level and forms the continental shelves.
Think of it this way: If you imagine the Earth like a giant apple, the continental crust would be the skin of the apple, while the oceanic crust would be the thin layer of skin just below the outer skin.
