• Largest layer of the Earth

• Made of hot, dense rock
• Temperature can go from
• 1600 degrees F near the top and 4000 degrees near bottom

MANTLE

OUTER CORE

• Very hot
• The metals it is made of are liquid
• Made of iron and Nickel

OUTER CORE

INNER CORE

• Temperatures can reach 9000 degrees F.

INNER CORE

OCEANIC CRUST

• Denser than continental crust
• Not as thick as continental crust
