The term for the imaginary line that divides the Earth into the Northern and Southern Hemispheres is the Equator. Located at 0 degrees latitude, the Equator is an essential reference point for geographic coordinates. It runs horizontally around the globe and is equidistant from the North Pole and the South Pole. The climate along the Equator is typically warm and humid, characterized by minimal seasonal variations. Many tropical rainforests, diverse ecosystems, and indigenous populations thrive in this region, making it impactful in terms of biodiversity and climate.
