... Below the Mantle is the Outer Core, which extends to a depth of about 1,400 miles. The core of the Earth is like a ball of very hot metals. The Outer Core is so hot that the metals in it are all in the liquid state. (molten metals) The outer core is composed of the melted metals of nickel and iron. ...
