Advertisements
उत्तर
The Equator is the longest parallel on the Earth. All other parallels become shorter polewards due to the spherical shape of the Earth. So the meridians near the poles have a narrow space. One degree of longitude is the longest at the equator (111 km) at 45° latitude it is 79 km, at 60° latitude it is 55 km and at poles, it is zero km.
