Show Answers:

  1. Latitude measures ___________________________
    North and South of the *EQUATOR*
  2. Longitude measures _________________
    East and west of the *Prime Meridean*
  3. Will latitude lines ever intersect?
    No, they are parellel to each other
  4. Do longitude lines run parallel to each other?
    No, they're distances are very close at the Northern and Southern parts of the word than they are if they are towards the center.
  5. Can you see Polaris if you are at the latitude 12 degrees South?
  6. If I were to stand at the latitude 29 degrees North, how high in the sky is Polaris?
    Polaris will be 29 degrees from the point where I stand. Remember that the angle of Polaris will always equal to the degrees of Latitude.
  7. How high do Latitude lines go up to?
    Latitude lines go up to 90 degrees North and South
  8. What is the highest measurement that you can get for a Meridean?
    180 degrees (the International Dateline)
  9. What are Longitude Lines called?
  10. Degrees of Latitude and longitude are broken up into smaller pieces called _______ with ______ in a degreeand then those are broken down to ________ with ______ in one _______.
    Minutes, 60, Seconds, 60, Minutes
  11. In one hour, the Earth rotates ___ because 360 degrees/24 hours = _____
    15 degrees. Fun fact, the Earth rotates at 75 miles per hour!
  12. There are 24 time zones on Earth, and each is ____ degreees apart
  13. Every 15 degrees of longitude, your time changes by __ hour(s)
  14. If it is 4:00 P.M. at 45 degrees West, what time should it be at 75 degrees East?
    It is midnight of the next day
  15. If it is 10:00 A.M. at 60 degrees East, what time should it be at 105 degrees West?
    It is 11 P.M. the day before.
  16. Contour Lines always point!!!_____________!!!

  17. What direction is this river flowing? How do you know/
    This river is flowing South (Southeast). I know because rivers always flow downhill, Rivers always flow to the ocean, and contour lines always point upstream

  18. Find the elevation of point D
  19. Be sure that you can draw profiles! Just like these two... Match up the paper to measure distance and label the elevation of every contour line. Then, graph it on the graph and make sure that the elevation is labeled correctly
    Moving on then...
  20. How would you find the gradient of a slope?
    First measure the distance, then measure the elevation change, and divide the change in elevation by the change in distance
  21. How can you tell what side of a hill is steepest?
    The contour lines will be closest together.
  22. In case of an emergency of a flood in a city, what actions could you take to protect the people and property?
    • Evacuate the city
    • Have a radio so you can hear what's going on
    • Have good batteries for flashlights
    • Anything else that is REALISTIC!

  23. What is the elevation of points A-E?
    • A 5,760 ft
    • B 5,600 ft
    • C 5,880 ft
    • D 5,641 ft - 5659ft
    • E 5,980 ft
