Longitudes are the angular lines drawn in north – south direction on the globe. They have the following characteristics:
1. The longest distance between the longitudes is on the equator.
2. On moving towards the poles from the equator, the distance between longitudes decreases.
3. All the longitudes on the poles.
4. Distance between latitudes on the equator is 111 km, on 30° north and south latitudes 96.5 km, on 60° north and south latitudes it is 55.4 km, and on 80° north and south latitudes it is 19.3 km and at 90° north and south latitude, it is zero.
5. There is a difference of 4 minutes on each longitude.
6. All 360° longitude lines when convert into a circle, they become greater circles.
