1. Layers of the Earth

2. Earth’s Layers How are the earth’s layers similar to an egg? Shell=crust Egg white=mantle Yolk=core

3. Make a model of Earth Using paper, make a pie-shaped piece to resemble the Earth. On the front, label the following: Inner core Outer core Mantle Crust Lithosphere

4. Inner core Outer core Mantle asthenosphere lithosphere crust

5. Open up your segment of the Earth and… 1.Mark the layers. 2.Label the state of matter of each layer. 3.What elements make up the core? 4.Label the thickness of each layer. 5.Label the temperature of each layer using the numbers below. 6. Lightly color your model. 12,000 F 9,000 F 4,500 F 100 F

6. State of Matter ElementsThicknessTemp Inner core Outer core Mantle Asthenosphere Lithosphere

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

8. Inner core Solid 1,200 km 12,000 F Nickel and iron

9. 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

10. Outer core Liquid 2,250 km 9,000 F 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.

12. Mantle solid and plastic 2,900 km 4,500 F

13. The mantle is a layer that is kind of like tar on a hot day. It flows, but very, very slowly..

14. Asthenosphere plastic

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

16. The lithosphere includes the crust of the Earth and the upper mantle.. It is solid.

17. The outermost layer of our Earth is called the crust.

18. Lithosphere, which includes the crust solid 120 km 100 F

20. As the liquid iron and nickel in the core circulate, it creates a magnetic field.

21. Oceanic and Continental Crust

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

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

24. What is this layer? State of matter? Mantle Plastic

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

26. Relative Masses - Earth http://www.uwgb.edu/dutchs/202ovhds/quakes.htm

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

28. Name the layer associated with this clip… CRUST

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

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

31. Name the layer associated with these graphics… CORE

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

33. Name the layer associated with this clip… Hot, Melted Fudge Wrapper Lithosphere mantle

34. 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

35. 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.
