- Inner Core. Temperature: 5,000°C – 6,000°C. State: Solid. Composition: iron and nickel. The Earth’s inner core is a huge metal ball, 2,500km wide. Made mainly of iron, the temperature of the ball is 5,000°C to 6,000°C – that’s up to 6,000 times hotter than our atmosphere and scorching enough to make metal melt!
- Outer Core. Temperature: 4,000°C – 6,000°C. State: Liquid. Composition: iron, nickel, sulphur and oxygen. This liquid layer of iron and nickel is 5,150km deep.
- Lower Mantle. Temperature: 3,000°C. State: solid. Composition: iron, oxygen, silicon, magnesium and aluminium. The lower mantle is found between 670km and 2,890km below the surface, and is made from solid rock.
