The Earth's inner core is mostly made of metal. In simple 6th-grade terms:

- Main materials: mostly iron, with some nickel.
- Also contains small amounts of lighter elements like sulfur, oxygen, and silicon.
- State: it is solid because the pressure deep inside Earth squeezes the metals together, even though it is extremely hot.
- Size and heat (simple facts): it is about 2,440 kilometers (about 1,520 miles) across and as hot as the surface of the sun (around 5,000–6,000 °C).
- Helpful idea: imagine a solid metal ball (inner core) surrounded by a molten metal ocean (the liquid outer core). The movement of that liquid outer core helps make Earth's magnetic field.
