A line of latitude located at 0 degrees is called the Equator. The Equator divides the Earth into the Northern and Southern Hemispheres and is significant in geographical, climatic, and ecological contexts. It represents the point where the sun is positioned directly overhead at noon during the equinoxes, resulting in consistent day-length and warmer temperatures year-round. Regions along the Equator typically experience tropical climates with lush vegetation and diverse ecosystems. The Equator serves as a reference point for navigational and geographical measurements, making it a critical feature of Earth’s coordinate system.
