The outer core of the Earth is a liquid layer about 2,260 kilometers thick. It is made of iron and nickel. This is above the Earth's solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface.
The outer core is about 1,400 miles thick, and it's made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form.

The Earth's core is the part of Earth in the middle of our planet. It has a solid inner coreand a liquid outer core.
The outer core is made up of an alloy of iron and nickel and small amounts of other dense metals like gold, platinum and uranium. The uniqueness about these metals found in the outer core is that they are entirely liquid and quite hot (approx. 7000–9000 °F).
The inner core is primarily made up of solid iron. Though the temperature in the inner core is greater than that of the outer core (
