Document Summary
Getting people or the world to interpret a map how you want them to will lead to much power. Latitude: measures north and south from the equator (horizontal lines) Lines of equal distance from the equator are called parallels or latitudes. The polar circumference of the earth is 24,860 miles. Degrees of latitude = circumferences divided by 360. In actual face - the size varies slightly - at the poles one degree of latitude is 69. 41 miles - while one degree on the equator is about 68. 70. Longitude: measure east and west distance from the equator (vertical lines) Unlike latitude there is no natural basis for determination of longitude. Prime meridian (date line) - at greenwich england. Distance measured by a degree of longitude varies significantly with that of latitude. It is expressed in degrees, minutes and second. It is a smaller closer to the poles.
