This shield was thought to encompass two other shells that encircle an inner core. This theory was published in the Philosophical Transactions of the Royal Society of London. Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.
