1. Structure of the Earth

2. The interior of the Earth is divided into several layers The interior of the Earth is divided into several layers

3. In the center of the Earth is the Inner Core. In the center of the Earth is the Inner Core. The Inner Core is made of solid iron and nickel. The Inner Core is made of solid iron and nickel. The Inner Core goes from 5150 – 6371 km below ground The Inner Core goes from 5150 – 6371 km below ground

4. The Inner Core is surrounded by the Outer Core. The Inner Core is surrounded by the Outer Core. The Outer Core is made of liquid iron and nickel The Outer Core is made of liquid iron and nickel The Outer Core goes from 2890-5150 km below ground The Outer Core goes from 2890-5150 km below ground The Outer Core’s material spins around the solid inner core, this creates the Earth’s magnetic field The Outer Core’s material spins around the solid inner core, this creates the Earth’s magnetic field

5. Around the Outer Core is the Mantle Around the Outer Core is the Mantle The Mantle is divided into two major layers, the Lower and Upper Mantle The Mantle is divided into two major layers, the Lower and Upper Mantle The Lower Mantle is made of solid rock, but very high pressure inside the Earth makes it act like a liquid. The Lower Mantle is made of solid rock, but very high pressure inside the Earth makes it act like a liquid. The Mantle goes from 65- 2890 km below ground The Mantle goes from 65- 2890 km below ground

6. Above the Mantle is the Crust Above the Mantle is the Crust The Crust is made of light, solid rocks. The Crust is made of light, solid rocks. The Crust goes from the surface of the Earth to 65 km below ground. The Crust goes from the surface of the Earth to 65 km below ground.

7. The Upper Mantle is divided into two layers, the Asthenosphere and the Lithosphere. The Upper Mantle is divided into two layers, the Asthenosphere and the Lithosphere.

8. The Asthenosphere is closer to the Earth’s Core. The Asthenosphere is closer to the Earth’s Core. It is made of “slush-like” rock- it can act like a solid or a liquid It is made of “slush-like” rock- it can act like a solid or a liquid

9. The Lithosphere is closer to the Earth’s Surface. The Lithosphere is closer to the Earth’s Surface. It contains both the uppermost part of the Mantle and Earth’s Crust It contains both the uppermost part of the Mantle and Earth’s Crust It is made of rigid (solid) rock It is made of rigid (solid) rock

10. Pressure increases as you get farther inside the Earth. Pressure increases as you get farther inside the Earth. The Crust has very low pressure. The Crust has very low pressure. The Inner Core has very high pressure. The Inner Core has very high pressure. Pressure Increases
