What divides latitude?

Latitude is divided into degrees, with the Equator at 0 degrees serving as the primary reference line. The lines of latitude, also known as parallels, run parallel to the Equator and are measured up to 90 degrees north (North Pole) and 90 degrees south (South Pole). Each degree of latitude is approximately 69 miles (111 kilometers) apart, and they help in determining a location's distance north or south of the Equator.
