Meridians or Longitudes - Teachoo.png

  • The meridians are lines that join the North Pole and the South Pole
  • They are used to locate places in the east and west directions
  • The meridian that passes through Greenwich , a place near London, is taken as the Prime Meridian
  • The distance of a place east or west of the Prime Meridian is measured as an angle, which is the longitude of that place
  • The longitude of a place is expressed in degrees, from to 180° E or 180° W
  • The meridians have the following characteristics:
    • They are all semi-circles of equal length
    • They form great circles when joined with their opposite meridians
    • They are farthest apart at the equator and converge at the poles
    • They divide the earth into two hemispheres: the Eastern Hemisphere and the Western Hemisphere
