Layers of the Earth Foldable
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
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
Outer Core Liquid Made up of Iron and Nickel Pressure is so great you would be squeezed into a tiny ball smaller than marble
Inner Core Solid Made up of Iron and Nickel Most dense of all the layers Pressure is the greatest here 9000 degrees- HOTTTT!!
