1. QQ:
What is Earth like under the surface? Describe what you would find if you dug down deep.
Would it be possible to dig through the center to China? Why or why not? Explain.

3. Don’t forget your reading!

5. Today’s Objective:
I am curious about the make up of the Earth and its history.

6. Humans have always tried to find ways to explore the world around them
Humans have always tried to find ways to explore the world around them. We’ve talked about the sky above us…now lets talk about the earth below us.

8. Journey to
the center
Of the Earth

9. QQ:
What is the scientific question that the expedition is trying to answer?
What is a major obstacle they have faced so far? What are they doing to counter it?
Who do you relate to most and why?

10. 4 Major Zones of Earth Crust Mantle Outer Core Inner Core
Chemical properties
Physical properties

11. Upper most part of earth’s shell
Crust:
Upper most part of earth’s shell
Part we walk on
Thin- 10 miles
Hard

12. 2 Kinds of Crust Continental * Of the land * 4 billion years old
Oceanic
* Of the ocean
* 180 million years old (or less)

13. Asthenosphere
Small layer beneath crust; the upper most part of the mantle
Some melting
Weak

14. Mantle: 82% of Earth’s volume
Upper Mantle - hard and rocky
Lower Mantle - rigid, hot, slow flow

15. Lithosphere
Refers to the crust, asthenosphere, and the mantle.

16. OUTER CORE
Molten
Super hot
Nickel and Iron

17. INNER CORE
SOLID IRON AND NICKEL

19. Crust and Mantle

21. A Poster of the Layers of the Earth:
Accurate
Details about each layer
Labels
Neat & colorful
Easy to read P

22. Billy Joel: We Didn't Start the Fire

23. Plate Tectonics: We Didn't Start the Fire Either!

24. QQ: Match each property with the layer(s) of earth it describes.
Solid
Oceanic
Iron and Nickel
Averages 10 miles thick
82% of Earth
Molten
Extreme pressure
Oldest crust
Most dense
Part of lithosphere

25. Tear it up!!!!!!!

26. The Rules:
There must be exactly 7 pieces when you are finished
No pieces can be discarded.
No rectangular pieces.

28. Arguing theoretical point….
Explains
Summarizes
Repeatedly Tested
No evidence to disprove it
Can be proven wrong

29. Wegener’s Hypothesis 1915 by Alfred Wegener
Continental Drift hypothesis
Super-continent: Pangaea

30. The Evidence! Shorelines fit like a puzzle Erosion? Same fossils
Land bridges

31. Mountain ranges fit
Unrelated
Climate: glacier movement
Different climate zones

32. Large continents broke away from lighter, smaller ones
Moved by gravity of moon
Not supported by math
Large continents broke away from lighter, smaller ones
Still searched for a theory

33. Types of Energy Transfer

34. Radiation: Passes through space in electromagnetic waves.
Conduction: Passes directly from one to another

35. Transfer of heat through movement of currents.
Convection:
Transfer of heat through movement of currents.

36. Energy Fueling the Earth
