Outer core. The outer core of the Earth is a fluid layer about 2,300 km (1,400 mi)[1] 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 (1,800 mi) beneath Earth's surface.
Report Abuse. The Earthâs core is only partially molten. The outer core is composed of molten iron and nickel, and the inner core is solid. The inner core has grown at the expense of the outer core over the 4.5 billion years of the Earthâs history.ut there is still a lot of heat inside the earth, so part of that metal core is liquid because the heat is pushing the stuff apart even more than the pressure is pushing it together. It is only really really deep that the pressure part of the issue takes dominance and the metal core turns solid.
