Journey to the Center of Earth
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)
Crust
The Mantle Semi-liquid (magma) 3000 km wide softer closer to the surface (Asthenosphere) Has convection currents that move the continental plates
The Mantle
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
