What is the term used for 0 degrees latitude?

The term used for 0 degrees latitude is the Equator. This is a significant geographical reference point that divides the Earth into the Northern and Southern Hemispheres. The Equator is situated equidistant from the North and South Poles, making it a key reference for understanding global geography, climate zones, and navigation. It is important as it typically experiences a warm climate year-round and plays a crucial role in the study of Earth's systems, such as weather patterns.

The other terms mentioned refer to different concepts in geography. The Prime Meridian, for example, is 0 degrees longitude, running from the North to the South Pole and serving as the reference point for measuring time zones and longitudinal coordinates. Meridians are lines of longitude that run vertically across the globe, while parallels are lines of latitude that run horizontally. Each of these plays a unique role in mapping and navigation, but none are synonymous with 0 degrees latitude like the Equator.
