The Outer Core is about 4000-5000 degrees Celsius. The Inner Core is so hot it causes all the metal in the Outer Core to melt into liquid magma. The Outer Core is composed of iron and some nickel. There is very few rocks and iron and nickel ore left in the Outer Core because of the Inner Core melting all the metal into liquid magma.The Outer Core is about 2200 km thick. It is the second largest layer and made entirely out of liquid magma. Because the outer core moves around the inner core, Earth's magnetism is created.A

Although it is one of the smallest, the Inner Core is also the hottest layer while Inner Core is a solid ball composed of an element named NiFe. Ni for Nickel and Fe for Ferrum also known as Iron.The Inner Core is about 5000-6000 degrees Celsius. It melts all metal ores in the Outer Core causing it to turn into liquid magma.
