5. Longitude is numbered from____________________degrees at the prime meridian to____________________degrees at the international date line.
6. A degree of latitude is approximately____________________miles at the equator and____________________miles at the poles. A degree of longitude is approximately____________________miles at the equator and____________________miles at the poles.
LENGTH OF A DEGREE OF LONGITUDE: A degree of longitude varies in length at different latitudes, becoming shorter as the latitude increases. The table below illustrates this:
|At Latitude||Statute Miles||At Latitude||Statute Miles|
Based upon the above table, answer questions 7-12.
7. How do the length of parallels differ as one approaches the poles?
8. What is the distance in miles around the world at the equator?
9. What is the distance around the world at 40 ° South Latitude?
10. At which latitude is the distance around the world one-half of the equatorial distance?

24. What large city has a similar latitude to that of Chicago (Europe)?
25. What is this cities Latitude and longitude?
26. What large city in Asia has a similar latitude to that of Chicago?
27. What is this city's Latitude and Longitude?
28. The term "antipodes" refers to two places on opposite sides of the earth so that a straight line drawn through the earth from one to the other passes through the center of the earth. To be exact antipodes, two places must be 180 ° of longitude away from each other, antipode must be as many degrees north latitude as the other is south latitude.
29. Below are some geographic grid coordinates for selected cities of the world. Examine an atlas and identify each city.
30. A number of cities are listed below. Using an atlas, give latitude and longitude of each in degrees and minutes.
31. Latitude and longitude readings can written in several different forms:
DDD.DDD = 38.4321°
DDD.MM.MMM = 38° 25.926'
DDD.MM.SS.SSS = 38° 25' 55.56"
a) Convert from DD.MM.SS.SSS to DD.MM.MMM
N52° 23' 48" W129° 55' 43" _________________________________
b) Convert from DD.MM.MMM to DD.DDDDDD
N87° 02' 45" W02° 34' 12" __________________________________
b) Convert from DD.DDD TO DDD.MM.SS.SSS
