NOTES:
  • What Is Latitude?
    • Lines
      • that run east to west
      • another name is "parallels"
    • Distance
      • in degrees
      • north or south of the Equator
      • each degree of latitude is about 69 miles
      • total of 90º North and another 90º South
  • Facts About Latitude
    • Where does it begin?
      • the Equator
        • an imaginary line that circles the Earth halfway between the North and South Poles
    • Where does it end?
      • the North and South Poles
    • What is its unit of measurement?
      • Degrees (minutes and seconds)
  • Important lines of latitude
    • The Equator = 0º
    • The Tropic of Cancer = 23 1/2ºN
    • The Tropic of Capricorn  = 23 1/2ºS
    • The Arctic Circle = 66 1/2ºN
    • The Antarctic Circle = 66 1/2ºS
    • The North Pole = 90ºN
    • The South Pole = 90ºS
