Here's the breakdown:
* Outer Core: This is the liquid layer of iron and nickel that surrounds the inner core.
* Inner Core: This is the solid center of the Earth. The intense pressure at the Earth's core is so great that it keeps the iron and nickel in a solid state, even though the temperature is extremely high (around 5,200°C or 9,392°F).
