If you mean Earth's core, it has two main layers:
- Outer core
- State: liquid
- Depth: from about 2,900 km down to ~3,480 km radius (thickness ≈ 2,260 km)
- Composition: mainly molten iron with nickel and some lighter elements (S, O, Si, etc.)
- Properties/role: convecting liquid that, together with Earth’s rotation, drives the geodynamo that produces Earth’s magnetic field; S-waves do not travel through it (evidence it’s liquid).
- Inner core
- State: solid
- Depth: roughly from ~3,480 km radius to the center (radius ≈ 1,220 km)
- Composition: mostly iron with some nickel and light-element impurities
- Properties/role: solid because of extremely high pressure despite high temperatures (≈5,000–7,000 K); gradual solidification of the inner core helps power convection in the outer core.
If you meant a different “core” (e.g., a CPU core or a planet other than Earth), tell me which and I’ll explain that instead.
