Latitude & Longitude • Longitude—Imaginary lines that run north-south around the globe and measure distance east and west of the prime meridian. Lines of Longitude
Latitude & Longitude • Latitude & longitude are used to determine absolute location.
Latitude & Longitude • Equator—an imaginary line circling the globe exactly half way between the North and South Poles. Red Line = Equator
Latitude & Longitude • Prime Meridian—imaginary line that runs around the globe from the North Pole, through Greenwich, England, and the South Pole. Yellow Line = Prime Meridian
