2. AAIM: HOW DO WE PROVE EARTH’S SHAPE?
DO NOW: WITH YOUR TALK PARTNER ANSWER THE QUESTION - If you went back in time and met up with someone who claimed that Earth is flat, what evidence would you present to them that their assertion is not true?
2. PERIOD 4 AND 9 TAKE OUT LAB # 5
AHW: 1. VOCAB DUE FRIDAY
2. LAB # 6 : DETERMINING EARTH’S SHAPE DUE THURSDAY

3. Earth's Shape

4. Is the Earth flat?

5. Square?

10. A. Is the Earth a perfect sphere?
The Earth’s true shape is an oblate spheroid
It is slightly flattened at the poles and slightly bulging at the equator.

11. However, if drawn to scale, it looks like a perfect sphere!

12. AAIM: How do we prove Earth’s shape?
DO NOW:
Answer the first Polaris question from handout on page 2.
AHW: Lab #6 due THURSDAY/ VOCAB FRIDAY

13. If the altitude of Polaris equals the latitude of the observer, then answer the following question!!!!
This question may require the use of the Earth Science Reference Tables.
To an observer in Buffalo, New York, the North Star, Polaris, is always located above the northern horizon at an altitude of approximately
23½° ° ½° °

15. If the altitude of Polaris equals the latitude of the observer, then answer the following question!!!!
This question may require the use of the Earth Science Reference Tables.
To an observer in Buffalo, New York, the North Star, Polaris, is always located above the northern horizon at an altitude of approximately
23½° ° ½° °

16. B.
Evidence of
Earth's Shape

17. 1. Photographs of Earth taken from Space
Best Evidence!

19. 2. As ships sail away from an observer, they drop below line of sight

21. 3. The shape of Earth’s shadow during an eclipse

22. 4.How could you use weight (gravitational pull) to prove the Earth is squished in at the poles??
You would weigh more at the poles since you are closer to the center of the Earth.
You would weigh less at the equator since you are farther from the center of the Earth.

23. AAIM: How do we prove Earth’s shape?
DO NOW:
Answer the first Polaris question from handout.
AHW: Lab #6 due THURSDAY/ VOCAB FRIDAY

24. If the altitude of Polaris equals the latitude of the observer, then answer the following question!!!!
This question may require the use of the Earth Science Reference Tables.
To an observer in Buffalo, New York, the North Star, Polaris, is always located above the northern horizon at an altitude of approximately
23½° ° ½° °

26. If the altitude of Polaris equals the latitude of the observer, then answer the following question!!!!
This question may require the use of the Earth Science Reference Tables.
To an observer in Buffalo, New York, the North Star, Polaris, is always located above the northern horizon at an altitude of approximately
23½° ° ½° °

27. 5. Polaris (North Star)
The North Star is located directly above Earth’s axis

28. Therefore, the altitude of Polaris = the latitude of the observer!
This method of navigation can only be used in the Northern Hemisphere.
