Definition
A line of latitude is an imaginary circle around the Earth, parallel to the Equator. It measures the distance north or south of the Equator in degrees. Think of it as one of the horizontal lines you see on a globe. Latitude is used to pinpoint locations on Earth and understand different climate zones. The Equator is 0 degrees latitude, while the North and South Poles are 90 degrees. These lines help define regions such as the tropics and the Arctic Circle. Understanding latitude is fundamental to geography and navigation.
