Document Summary
So, all other locations fall between those degrees. Since the earth is not quite spherical, the length of 1 degree of latitude is slightly larger at the poles (vs. the equator) Equator: 1 degree latitude = 110. 6 km (68. 7 mi. ) Poles: 1 degree latitude = 111. 7 km (69. 4 mi. ) 8/28/2013: latitude cont, close to the equator are the low latitudes. Close to tropics: close to poles are the high latitudes. 40-69 degrees are mid latitudes o: equator is great circle, all other latitudes are small circles, longitude, measures distance east and west of prime meridian. Goes through greenwich england: run north to south, aka meridians = lines of equal longitude, all the same size, but not parallel, range is 0 to 180 degrees. 180 is int. date line: a pair of longitudes makes a great circle, degree breakdown, used to specify location. Portrayal of earth: globes are accurate, but inconvenient, air photos/satellite images are photos, not maps, maps.
