GROUP A. THE EARTH AS A GLOBE 

 Answer one question from this group 



1. In his final dash for the Pole over the Arctic ice, Commander Peary found 



his compass of no value in determining directions; why was this so? 

 How could he know when he had arrived at the North Pole ? 



2. The earth is an oblate spheroid; to what is its shape due? What is the 



approximate amount of flattening at the Poles ? What facts show that 

 the earth is approximately a sphere ? 



GROUP B. THE OCEAN 

 Answer one question from this group 



3. Under what conditions do coral reefs develop in the ocean? What is an 



atoll? a barrier reef? Corals are found in the region of the Bermuda 

 Islands, latitude 32 degrees 20 minutes North. They do not occur about 

 the Galapagos Islands under the Equator westward from South America. 

 Account for this. 



4. Account for the clockwise circulation of the water about the North Atlantic; 



the counter-clockwise circulation about the South Pacific; the seasonal 

 alternation in direction of circulation about the North Indian Ocean. 



GROUP C. THE ATMOSPHERE 

 Answer two questions from this group 



5. How do observations of meteors give us knowledge of the depth of the 



atmosphere? Based on such observations, how deep is it? Why are 

 dust and water vapor confined to the lower air ? 



6. Why may we find lower temperatures, in general, either by traveling pole- 



ward or by ascending a mountain ? Why has Lisbon, Portugal, a more 

 equable climate than New York ? and why are the climates of both more 

 equable than that of St. Louis, Missouri ? 



7. The mountainous islands of the West Indian and Hawaiian groups have a 



wet and dry coast; locate and explain. Why has the City of Mexico a 

 wet summer, and the city of San Francisco a wet winter ?
