II. Short answer. Answer the following.

  1. What is the difference between latitude and longitude and why are they important? Latitudes are parallel, longitudes converge at the poles; they provide a grid system for navigating across our planet
  2. What are the minimum and maximum number of degrees of longitude? 0, 180
  3. Where is zero degrees longitude? Greenwich, England
  4. Where is 180 degrees longitude? in the Pacific Ocean
  5. How do we differentiate between longitudes east or west of 0 and 180 degrees longitude? using East and West as designations
  6. What are the minimum and maximum number of degrees of latitude? 0, 90
  7. Where is zero degrees latitude? the equator
  8. Where is 90 degrees latitude? the poles, N or S
  9. How do we differentiate between latitudes north or south of 0 and 90 degrees latitude? using North and South as designations
  10. What are parallels and meridians? synonyms for latitude and longitude, respectively Which are equidistant from each other?parallels Which converge at the poles? meridians
  11. What are the major climate zones, where are they and why are they important? tropical, temperate, polar: see defintions above. they broadly define climate and allow us to make inferences on the seasonal cycle of change in the ocean
  12. What are the names of the parallels that define the climate zones? tropic of cancer and capricorn; arctic and antarctic circles
  13. What is the difference between the prime meridian and the international date line? 180 degreees! they are at opposite ends of the planet
  14. What is Greenwich mean time (GMT) and why is it important? it's the standard for all time. it allows us to report time with no ambiguities about the time; in other words, we can intercompare times anywhere in the world when they are reported in GMT

III. Latitude-longitude problems. Answer the following.

1.        You are standing at the intersection of the prime meridian and the international date line in the northern hemisphere. Where are you?

You are standing at the North Pole

2.        You are standing at the intersection of the prime meridian and the equator. What is your latitude and longitude?

You are at 0 degrees latitude, 0 degrees longitude

3.        You are standing at the intersection of the international date line and the equator. What is your latitude and longitude?

You are at 0 degrees latitude, 180 degrees longitude

4.        You are standing at the intersection of the international date line and the Tropic of Cancer. What is your latitude and longitude? Don't forget to indicate degrees north or south for latitude.

23.5 degrees N latitude; 180 degrees longitide

5.        You are standing at the intersection of the prime meridian and the Tropic of Capricorn. What is your latitude and longitude? Don't forget to indicate degrees north or south for latitude.

23.5 degrees S latitude, 0 degrees longitude

6.        You are standing at the intersection of the international date line and the Antarctic Circle. What is your latitude and longitude? Don't forget to indicate degrees north or south for latitude.

90 degrees S latitude, 180 degrees longitude

7.        You are standing at the intersection of the prime meridian and the Arctic Circle. What is your latitude and longitude? Don't forget to indicate degrees north or south for latitude.

90 degrees N latitude, 0 degrees longitude

8.        What is the latitude and longitude (to the nearest whole degree) of the town you live in?

see lecture notes for web site

9.        You are standing at 120 degrees east and 45 degrees north. You move 10 degrees west and 10 degrees south. What is your new latitude and longitude? Don't forget to indicate degrees east or west and degrees north or south.

110 degrees east, 35 degrees north

10.     You are standing at 120 degrees east and 45 degrees north. You move 180 degrees west and 90 degrees south. What is your new latitude and longitude? Don't forget to indicate degrees east or west and degrees north or south.

60 degrees west, 45 degrees south

15.     Take a position anywhere in the world. Make up your own latitude and longitude. Make up your own problem. See if you can come up with the correct answer. If you understand latitude and longitude, these problems are a piece of cake.

You are at 0,0 and don't move. Where are you? Still at 0,0. Wherever you go, there you are!
