Earth globe and inner cores. Earth hemisphere global map,centred on the northern Atlantic Ocean,with the Earth's inner and outer cores (orange) made visible. The outer core is a liquid layer of iron and nickel,around 2160 kilometres thick. The inner core is a solid sphere of iron-nickel alloy,with a radius of 1320 kilometres. Surrounding these is the mantle,a layer some 2900 kilometres thick consisting of both sold and semi-molten rock. The outer layer is the crust (around 35 kilometres thick). The Earth's diameter is around 12,742 kilometres | |
