Abstract

Latitudes and longitudes are imaginary circles that run East-West and North-South respectively, on the earth’s surface. Unlike longitudes (or meridians), latitudes (or parallels) vary in length. The Equator is the longest. The others decrease in size till the poles, which are just points. The length of the other latitudes can be expressed as fractions of the length of the Equator.
