The outer core of the Earth is a fluid layer about 2,300 km thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km beneath the Earth's surface. Unlike the inner core, the outer core is liquid. The inner core is also referred to as the solid core.
