6. The Mantle Semi-liquid (magma) 3000 km wide softer closer to the surface (Asthenosphere) Has convection currents that move the continental plates

7. The Mantle

8. The Outer Core Liquid, molten rock Very high temperatures Made of Nickel and Iron

9. The Inner Core Solid layer Solid because of high pressure Mostly Iron 6,000 degree Celsius. 2,100 km wide
