In a simplified view, the continental crust possesses a layered structure: On the bottom is a layer of igneous rock (molten rock that has hardened, such as granite) over which lies a thin layer of sedimentary rocks (rocks formed by sediment and fragments that water deposited, such as limestone and sandstone).
