The thinnest part of the Earth is the oceanic crust, which underlies the ocean basins. It typically ranges from about 5 to 10 kilometers (3 to 6 miles) in thickness, significantly thinner than the continental crust, which can be up to 70 kilometers (43 miles) thick. The oceanic crust is primarily composed of basalt, while the continental crust is mainly composed of granitic rocks.
