Letters E or W are used to represent direction.Letters N and S are used to denote the location.Values for longitude range from 0 (the Prime Meridian) to 180 degrees.Values range from 0 (the Equator) to 90 (the north and south poles).
The imaginary lines that run from east to west connecting all locations on a map are known as parallels or latitudes. This is the key difference between parallels and meridians. Parallels run from east to west and never intersect with each other whereas meridians run from north to south and intersect at the north and south poles. The world map we use is marked with countries, continents, and oceans, but have you ever wondered about the different lines that run across the map? These lines, known as parallels and meridians, help us to figure out the exact dimension and direction of a location. The terms Parallels and Meridians are often found in the context of geography and science.
