How Many Lines of Latitude Are There on Earth?

The equator lies halfway between the North Pole and the South Pole. Lines of latitude are always parallel to the equator and equidistant from one another. Every line of latitude is 69 miles away from both the previous line and the next line. The degree designated to each line is the angular distance between it and the equator. Latitudes north of the equator are often termed as "positive," while latitudes to the south are called "negative."
