The outer core of the Earth is a liquid mix of elements, mostly iron and nickel, with smaller amounts of silicon and oxygen. It goes from a depth of 2550 km below the surface of the Earth to 4750 km at the boundary of the inner core, during which time the temperature increases from 4500 to 5500 degrees Celsius.
