Latitude refers to horizontal lines that indicate a location's distance north or south of the equator. Longitude refers to vertical lines that indicate a location's distance east or west of the Prime Meridian, which is an imaginary line running from the North to the South Pole.
Latitude lines stretch from 0 to 90 degrees above and below the equator. They are parallel to each other and to the equator. The lines are longer near the equator and become shorter towards the poles. All of the locations along the same latitude fall in the same hemisphere on Earth, but do not necessarily share the same time zone. The lines measure up to 180 degrees between 90 and -90. The latitude of a location determines its climate and weather conditions.
Longitude lines stretch from 0 to 180 degrees from the Meridian. They are not parallel and converge at the poles. All longitude lines are of the same length. Locations along the same longitude line share a time zone, although they may not be in the same hemisphere. The lines measure up to 360 degrees from 180 to -180. Scientists measure longitude in degrees, minutes and seconds, and use it to determine time zones.
