Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0?, the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90?N. This is the highest latitude possible.
Similarly, it is asked, which is the longest latitude and why?
On a globe of the Earth, lines of latitude are circles of different size. The longest is the equator, whose latitude is zero, while at the poles--at latitudes 90° north and 90° south (or -90°) the circles shrink to a point.
Which latitude is a great circle?
The Equator is another of the Earth's great circles. If you were to cut into the Earth right on its Equator, you'd have two equal halves: the Northern and Southern Hemispheres. The Equator is the only east-west line that is a great circle. All other parallels (lines of latitude) get smaller as you get near the poles.
What is the range of latitude and longitude?
Latitudes range from 0 to 90. Longitudes range from 0 to 180. Use N, S, E or W as either the first or last character, which represents a compass direction North, South, East or West. The last degree, minute, or second of a latitude or longitude may contain a decimal portion.
