Parallels of longitude, commonly called meridians, are imaginary vertical lines running from the North Pole to the South Pole. They measure the distance east or west of the Prime Meridian, which is 0° longitude. These lines help in determining time zones and are crucial for global navigation and mapping.

Parallels of longitude, more accurately known as meridians, are imaginary vertical lines that extend from the North Pole to the South Pole. Unlike parallels of latitude, these lines are not equidistant but converge at the poles. The Prime Meridian, located at 0° longitude in Greenwich, England, serves as the starting point for measuring longitude. Longitude is measured in degrees east or west of the Prime Meridian, up to 180°. Meridians are essential for determining geographical location, time zones, and global navigation. They play a key role in mapping the Earth’s surface and are used in conjunction with latitude lines to pinpoint exact locations.
