Earth rotation and latitude. (A) The equator is halfway between the poles. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. (B) Latitudes are measured as the angle away from the equator. The latitude 45 degrees north marks the halfway point between the equator and the North Pole. The equator is at 0 degrees latitude, and the poles are at 90 degrees latitude north and south. Latitudes do not exceed 90 degrees.
