2 Journey to the Center of Earth

3 Layers of the Earth Crust Mantle Outer Core Inner Core

4 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)

5 Crust

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

7 The Mantle

8 The Outer Core Liquid, molten rock Very high temperatures Made of Nickel and Iron

9 The Inner Core Solid layer Solid because of high pressure Mostly Iron 6,000 degree Celsius. 2,100 km wide

10 The Core
