* Inner Core: This is the solid, innermost part of the Earth, made up primarily of iron with a small amount of nickel. It's incredibly hot, reaching temperatures of around 5,200°C (9,392°F). The immense pressure at the center of the Earth is what keeps it solid despite the high temperature.
* Outer Core: This is a liquid layer surrounding the inner core, also primarily composed of iron and nickel, along with other elements like sulfur and silicon. The outer core is still incredibly hot (between 4,500°C and 5,500°C or 8,132°F and 9,932°F) and is in constant motion, generating the Earth's magnetic field.
There are no geographical divisions like "south" and "west" within the Earth's core. These terms relate to directions on the Earth's surface, not its internal structure.
