| Feature | Longitude (Meridians) | Latitude (Parallels) | | :--- | :--- | :--- | | | North-South | East-West | | Measurement | East or West of the Prime Meridian | North or South of the Equator | | Length | All meridians are equal length | Parallels get shorter toward poles | | Intersect | Intersect at the poles | Never intersect | | Purpose | Determines time zones | Determines climate zones |

Meridians of longitude, also known as lines of longitude, are imaginary lines that run from the North Pole to the South Pole on a globe or map. They are used to measure the distance east or west of a point from a reference meridian, which is the Prime Meridian. The Prime Meridian passes through Greenwich, England, and is designated as 0° longitude.

The primary practical purpose of meridians is the calculation of time. Because the Earth rotates 360 degrees in 24 hours, it rotates 15 degrees every hour. Therefore, Earth is divided into 24 standard time zones, each theoretically spanning 15 degrees of longitude.
