What geographic feature is at 0 degrees latitude?

The geographic feature located at 0 degrees latitude is the Equator. This is a significant imaginary line that divides the Earth into the Northern and Southern Hemispheres. The Equator represents the widest part of the Earth and is equidistant from the poles. It is also the starting point for measuring latitude in degrees, with locations north of the Equator designated as positive latitudes and those to the south as negative latitudes.

The other geographic features listed, such as the Prime Meridian, which is at 0 degrees longitude, and the Tropic of Cancer, which is situated at approximately 23.5 degrees north latitude, do not represent the equatorial line. The Arctic Circle, located at around 66.5 degrees north latitude, marks the region that experiences continuous daylight or darkness at certain times of the year, but it is not related to 0 degrees latitude. Thus, the Equator is the sole feature corresponding to 0 degrees latitude.
