3 LatitudeLatitude lines are imaginary horizontal lines on a world or large area map. Latitude lines separate the world into Northern and Southern hemispheres and range between 0 degrees at the Equator and 90 degrees at the North and South Poles.
4 LongitudeLongitude lines are imaginary vertical lines on a world or large area map. Longitude lines separate the world into the Eastern and Western hemispheres and range between 0 degrees at the Greenwich Meridian (also known as the Prime Meridian) and 180 degrees east and west of Greenwich at the International Date Line.
5 Each degree of latitude and longitude is subdivided into 60 equal parts called minutes and each minute is divided into 60 equal parts called seconds. On the surface of earth, one degree of either latitude or longitude is about 110 km (69 miles) although it is slightly more at the poles as the earth is not a perfect sphere.
