Answer Details

The angular distance of a point on the Earth's surface measured in degrees from the centre of the Earth east or west of the Greenwich Meridian is known as longitude. Longitude lines run from the North Pole to the South Pole, and the prime meridian, or zero longitude, runs through the Royal Observatory in Greenwich, London. Longitude is used together with latitude to specify the geographic coordinates of a location on the Earth's surface, and it is an essential element in navigation and timekeeping.
