Firstly, different maps or atlases draw lines of latitude andlongitude in varying degrees apart. Although most maps havedifferences of 10 degrees apart, atlases can be as close as 1 or 2degrees.Secondly, you might be referring to the major lines of latitudeand longitude, such as the Equator and the Prime Meridian. Somemaps that are very small only show the major lines of latitude andlongitude.
