Layers of the Earth

• Crust

• Mantle

• Outer Core

• Inner Core

The Crust

• Layer that we live on (Lithosphere)

• 5-25 miles thick

• Consists of cooled rock

• Thinnest layer of the earth

• There are 2 kinds of Crust: Continental (thicker) and Oceanic (thinner)

The Mantle• Semi-liquid

(magma)

• 3000 km wide

• softer closer to the surface (Asthenosphere)

• Has convection currents that move the continental plates

The Outer Core

• Liquid, molten rock

• Very high temperatures

• Made of Nickel and Iron

The Inner Core

• Solid layer• Solid because of high pressure• Mostly Iron• 6,000 degree Celsius.• 2,100 km wide
