The composition of the Earth's layers is as follows: the mantle is primarily composed of silicate rocks rich in iron and magnesium; the crust is made up of lighter silicate rocks, with the oceanic crust primarily composed of basalt and the continental crust made up of granite and other rocks; the inner core is primarily composed of solid iron and nickel; the outer core is also composed of iron and nickel, but it is in a liquid state.
