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
