1. Layers of the Earth

2. Earth’s Layers How are the earth’s layers similar to an egg? Shell= crust Layers Limitations?

3. Make a model of Earth You will need to know the following: 1. Inner core Outer core Lower Mantle Asthenosphere Lithosphere (includes Crust) 2. What states of matter each layer is 3. Elemental make-up 4. Layer that gives us our magnetic field.

4. Outside of Foldable Lithosphere Asthenosphere Mantle Outer Core Inner Core Asthenosphere Lower Mantle Outer Core Inner Core

5. Inner core Outer core Lower Mantle Asthenosphere (part of mantle) Lithosphere (mantle and crust)

6. What is the center layer called? What state of matter is it? What is it made of? SOLID IRON AND NICKEL INNER CORE

7. Inner core Solid Nickel and iron Deepest layer, so…. Greatest pressure Also the Hottest! (10,000 0 F)

8. The next layer of the Earth after the inner core would be the…… What state of matter is the outer core? What elements are in the outer core? OUTER CORE LIQUID Iron and Nickel

9. Outer core Liquid Due to flow of liquid metal, gives us our magnetic field. Nickel and iron

10. As the liquid iron and nickel in the outer core circulate, it creates a magnetic field. Where is there liquid nickel and iron?

11. Why do you think the inner core is solid and the outer core is liquid? The core of our Earth is tremendously hot. It is believed to have a temperature of 7,000 degrees Celsius. Pressure keeps the inner core a solid, but allows the outer core to be a melted, liquid state.

13. So what 2 things increase as you travel toward the Earth’s center? Heat and Pressure!

14. What 2 things increase as you travel towards the Earth’s center? Lithosphere Asthenosphere Mantle Outer Core Inner Core Heat & Pressure Asthenosphere Lower Mantle Outer Core Inner Core NOTE: In your journal, write what you see in red. This goes next to the foldable.

15. Lower Mantle solid Magnesium, Iron Silicon, Oxygen

16. Asthenosphere (upper layer of the mantle) Plastic (flows, like Peanut butter) Convection currents here move land! Magma

17. The asthenosphere is just below the lithosphere. It is part of the mantle. The asthenosphere is rock that flows slowly, like hot asphalt or peanut butter.

18. The lithosphere includes the crust of the Earth and the upper mantle.. It is solid. Crust: Oxygen and Silicon

19. Outside of Foldable Lithosphere Asthenosphere Lower Mantle Outer Core Inner Core Color a thin line on the outside of the foldable (top of Lithosphere) to represent the crust (shown in red here). Crust (solid) O (Oxygen) & Si (Silicon)

20. The outermost layer of our Earth is called the crust. Lava Mountains Water Least pressure Coolest

21. Lithosphere, which includes the crust solid

22. Oceanic and Continental Crust 4 -7 miles thick 65 miles thick

23. Deepest hole drilled? Today, the deepest hole ever created by humankind lies in Middle East. 7.5 miles into the Earth's crust. The drill spent twenty-four years chewing its way to that depth

24. Outside of Foldable Lithosphere Asthenosphere Lower Mantle Outer Core Inner Core Mantle

26. What is this layer? State of matter? Inner core Solid

27. What is this layer? State of matter? Lithosphere Solid

28. What is this layer? State of matter? Lower Mantle Solid

29. What is this layer? State of matter? Outer core Liquid

30. What is this layer? State of matter? Asthenosphere Plastic (Layer below lithosphere)

31. Name the layer associated with this clip… CRUST

32. Name the layer associated with this clip… OUTER CORE

33. Name the layer associated with this clip… OCEANIC CRUST

34. Name the layer associated with these graphics… CORE

35. Name the layer associated with this clip… OUTER CORE

36. Name the layer associated with this clip… Hot, Melted Fudge Wrapper Lithosphere asthenosphere

37. Name the 5 basic layers of the Earth (mentioned in your book) in order of their temperatures, from highest to lowest.

38. Convection – What is it? Why do we care? Convection Source: http://www.uwgb.edu/dutchs/EnvSC102Notes/102HowEarthWorks.HTMhttp://www.uwgb.edu/dutchs/EnvSC102Notes/102HowEarthWorks.HTM

39. 1200 km 2200 km 2900 km 5-40 km Our scale is: 60 km = 1 mm Label the layers and state of matter. Show convection currents in mantle.
