The equator is an imaginary line around the middle of Earth. It divides the planet into the Northern Hemisphere and Southern Hemisphere.
Why the equator matters
The equator is 0 degrees latitude. It is a reference line used in maps, navigation, climate patterns, and geography. Places near the equator often receive strong sunlight throughout the year.
Equator and coordinates
The equator is part of the latitude system. Together, latitude and longitude help identify locations on Earth.
The equator is not a physical mark on the ground; it is a geographic reference line.
