The imaginary line that divides the Earth into the Northern and Southern Hemispheres is known as the Equator. The Equator is located at 0 degrees latitude and circles the Earth horizontally. It serves as a reference point for latitude, helping to define geographic coordinates. The areas north of the Equator are characterized by different climates and ecosystems compared to those to the south. The Equator also influences weather patterns and biodiversity. Many countries that lie on the Equator enjoy a tropical climate year-round due to consistent sunlight.
