The Arctic Circle.
Latitude lines run from east to west, parallel to the equator. Longitudinal lines are perpendicular to latitude lines and run north to south.
Lines of latitude run parallel to the Equator (which is zero latitude).
Lines of longitude run vertically from the north pole to the south pole. The Prime Meridian (zero longitude) runs through the Greenwich Observatory, London, England. Lines that run parallel to the Equator (zero latitude) are lines of latitude.
The key lines are latitude and longitude. These are based on specific points. The equator is the latitude around the center of the earth. Longitude is measured from the Prime Meridian, which goes through the Greenwich Observatory in England.The Tropics and the Arctic/Antarctic Circle are also key.
Lines of latitude run parallel to the equator. Lines of longitude run vertically - passing through both poles.
You have answered the question for yourself ; They are 'Latitudes''. Longitudes (Meridians) are lines that run North to South from the North Pole to the South Pole. Longitudes come to a point at the poles, but spread out to a maximum at the Equator.
The lines that run north and south "or long ways" are longitude lines. East and west are latitude lines.
Lines of latitude circle the Earth in an east-west fashion. so no
Lines of latitude run east-west and measure north-south.
Lines of Latitude run horizontally round the World and parallel to the Equator.
Lines of latitude circle the earth, parallel to the equator.
