Which direction do Latitude (Parallel) lines run?

Latitude lines, commonly referred to as parallels, run east to west around the Earth. This system is integral to the geographic coordinate system, which allows for the pinpointing of locations based on their angular distance north or south of the equator. Each line of latitude is parallel to the equator and is used to divide the planet into different climatic zones, affecting weather and vegetation patterns. Since these lines are used to measure distances in degrees from the equator (0° latitude) to the poles (90° north or south), they maintain a constant distance from each other, running parallel to one another in an east-west orientation. This design is crucial for navigational purposes and for understanding global geography.
