Here's the breakdown:

* Inner Core: The innermost part of the Earth is a solid ball of mostly iron with a temperature of around 5,200°C (9,392°F). The immense pressure at the core, about 3.3 million times that at sea level, is so great that it keeps the iron from melting even though it's incredibly hot.

* Outer Core: Surrounding the inner core is the liquid outer core, also primarily made of iron and nickel. This layer is less dense than the inner core and is where the Earth's magnetic field is generated.

So, the Earth's core is a complex structure with both solid and liquid components.
