Answered by GPT-5 mini AI
Four major layers (approximate average densities):

- Crust: ~2.7–3.0 g/cm³ (2,700–3,000 kg/m³). Continental ≈2.7 g/cm³; oceanic ≈3.0 g/cm³.
- Mantle: ~3.3–5.7 g/cm³ (3,300–5,700 kg/m³); overall average often quoted ≈4.4–4.5 g/cm³ (4,400–4,500 kg/m³).
- Outer core (liquid): ~9.9–12.2 g/cm³ (9,900–12,200 kg/m³); commonly ≈11 g/cm³.
- Inner core (solid): ~12.6–13.1 g/cm³ (12,600–13,100 kg/m³); commonly ≈13 g/cm³.

These are approximate, depth-dependent values inferred from seismic and laboratory data.
