Crust 6-70 km thick Very light; only 1% of Earth’s total mass Made up of rock Two types of crust Oceanic All of the ocean floors Continental Includes all continents and islands

Mantle Thickest layer of Earth 2900km thick 64% of Earth’s mass Made of hot rock that is less dense than the core 870-4400 degrees Celsius

Outer Core Composed of liquid iron and nickel 2300km thick Temperature and pressure here are lower than in the inner core; that is why this layer is a liquid 4400-6100 degrees Celsius

Inner Core Solid layer of nickel and iron High temperature and pressure 2400km in diameter 7000-8000 degrees Celsius

Lithosphere Earth’s crust and the top of the mantle

Asthenosphere Under the lithosphere Softer and hotter rock is located here
