Earth's internal structure. Cutaway computer artwork showing the direction of the Earth's rotation (arrows),and the different layers that make up its structure. The external layer (crust) includes the land (green) and water (blue),and is around 35 kilometres thick. The mantle is a viscous layer of rocks under high pressures and temperatures,and extends down to around 2890 kilometres. The outer core is a liquid layer of iron and nickel,around 2260 kilometres thick. The inner core (centre) is a liquid sphere of a iron-nickel alloy,with a radius of 1220 kilometres | |
