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:

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.
