Usually, the difference in latitude largely affects the climates or weathers of that region.
Other latitudes of particular importance are the tropic of Cancer (latitude 23°27' north), the tropic of Capricorn (latitude 23°27' south), the arctic circle (latitude 66°33' north) and the antarctic circle (latitude 66°33' south). Only at latitudes between the tropics is it possible for the sun to be at the zenith. Only north of the arctic circle or south of the antarctic circle is the midnight sun possible.
All locations of a given latitude are collectively referred to as a parallel, because they are coplanar, and all such planes are parallel to the equator.
One minute of arc of latitude is approximately one nautical mile.
