What is the degree of difference between each line of latitude and longitude?

Firstly, different maps or atlases draw lines of latitude and longitude in varying degrees apart. Although most maps have differences of 10 degrees apart, atlases can be as close as 1 or 2 degrees.

Secondly, you might be referring to the major lines of latitude and longitude, such as the Equator and the Prime Meridian. Some maps that are very small only show the major lines of latitude and longitude. The difference between the equator and the Tropics of Cancer and Capricorn is 23.5 degrees, while the difference between the equator and the Arctic and Antarctic Circles is 66.5 degrees. The difference between the Prime Meridian and the International Date Line is 180 degrees.
