A meridian is a measurement of longitude that extends from the north pole to the south pole and locates geographic points via their east/west location from Greenwich, England (the prime meridian). Whereas, a parallel is measure of latitude that locates geographic points based upon the degree to which they are North or South of the Equator, or middle line.

Work Step by Step

Longitude and Latitude are imaginary lines on the Earth's angular surface that are used to locate points. Longitude lines are zeroed at the Royal Observatory in Greenwich, England and extend east and west 180 degrees. Lines of latitude are zeroed at the Equator which is the imaginary middle, or waist, of the earth. Longitude lines are called meridians whereas lines of latitude are called parallels as they do not intersect.
