The U.S. has two main sets of parallel latitudinal lines that cross the country: the Arctic Circle (66°34’N) and the Antarctic Circle (66°34’S). In between these two circles lies a band known as the tropics, which includes all areas between 23°26′ N and 23°26′ S latitude.

The 48 conterminous states of the United States are between 67° and 125° W. Longitude. The arrows in figure 8-2 labeled “LONGITUDE” point to lines of longitude. Any specific geographical point can thus be located by reference to its longitude and latitude.

Lines of latitude are often referred to as parallels. Longitude: (shown as a vertical line) is the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian.
