The Earth's core is made up primarily of the metals nickel and iron. The inner core is mostly iron, while the outer core is composed of both nickel and iron. The inner core is very hot at 9,000 to 13,000 degrees Fahrenheit, however, the iron is not liquid because of the pressure of the Earth pressing in on it.
The Lower Mantle- part of the second layer of the earth which is mostly melted rock. The whole mantle going down is 1800 miles down. The Outer Core- is made up of liquid metals mostly iron nickel and minor sulfur. The outer core goes 1375 miles down. The Inner Core- the most inner layer of the earth which is solid and made of iron and nickel. The inner core is 1750 miles to the center. How the layers of the Earth were created.
