The Earth's layers vary in thickness. The crust is thinnest under the oceans, around 5-10 km thick, and thicker under continents, around 20-70 km thick. The mantle extends from the crust to about 2,900 km below the surface, while the outer core is about 2,300 km thick and the inner core is about 1,200 km thick.
