khatulistiwa, or the Equator, is an imaginary line that divides the Earth into the Northern and Southern Hemispheres. It is located at 0 degrees latitude and is significant for its role in climate and geography. Regions near the Equator typically experience a tropical climate, characterized by warm temperatures and high humidity throughout the year. The Equator passes through several countries, including Ecuador, Colombia, Brazil, Gabon, and Indonesia. This line is also important for navigation and understanding Earth's rotation, as it represents the point where the sun is directly overhead at noon during the equinoxes.
