The Equator, an imaginary line at 0° latitude, bisects the Earth into the Northern and Southern Hemispheres. The Prime Meridian, not the Equator, is the line of zero degrees longitude. Due to its position directly between the North and South Poles, the Equator receives the most direct sunlight, resulting in the hottest temperatures on Earth. It is also precisely equidistant from both poles, ensuring an equal division of the hemispheres.
