1. Layers of the Earth Foldable

2. Crust Outermost layer Made up of Continental crust & oceanic crust
Very thin (25 miles deep)
Made up of rocks (Oceanic-basalt) (Continental-granite)
Least dense

3. Mantle Layer under the crust
Convection Currents occur here to allow plates to move
Thickest layer (1800 miles)
Flows like thick liquid (magma)-very hot

4. Outer Core Liquid Made up of Iron and Nickel
Pressure is so great you would be squeezed into a tiny ball smaller than marble

5. Inner Core Solid Made up of Iron and Nickel
Most dense of all the layers
Pressure is the greatest here
9000 degrees- HOTTTT!!
