Earth's Outer Core
The Outer Core of the earth is a layer about 2,299 km think and made out of iron and nickel which lies above the earth's solid Inner Core and under the Mantle. The Outer Cores temperature is about 4400 degrees celsius in the outer region to about 6100 degrees celsius near the Inner Core. The Outer Core isn't under enough pressure to be solid so it's semisolid.
