					Latitude and Longitude
Grid System
 Lines of latitude and longitude cover the entire earth.
 They allow us to find any location on Earth.
 Lines of latitude and longitude are noted with cardinal
  directions.
 The cardinal directions are North, South, East and
  West




Lines of Latitude run East      Lines of Longitude run North
to West                         and South.
Latitude
 The starting point for measuring latitude is the Equator.
 The Equator is a line of latitude (0*).
 The Equator runs East and West and divides the Earth into two
  equal parts.
 Lines of latitude North of the Equator are labeled with an “N”.
 Lines of latitude South of the Equator are labeled with an “S”.
 You already know the location of several lines of latitude from
  studying Global Winds.

       Latitude North




        Latitude South
Longitude
   The starting point for measuring Longitude is the Prime Meridian.
   The Prime Meridian is located at Greenwich, England.
   The Prime Meridian is at 0* Longitude.
   The ending point for the Prime Meridian is on the other side of the
    Earth and is located at 180* Longitude.
   The United States is located West of the Prime Meridian.
   Lines of Longitude west of the Prime Meridian are labeled with a
   “W”.
   Lines of Longitude East of the Prime Meridian are labeled with an “E”.


                                         Longitude West of the Prime
                                         Meridian.



                                          Longitude East of the Prime
                                          Meridian.
Locating points on the Earth
Using Latitude and Longitude
   Lines of Latitude and Longitude are measured in
    degrees.
   Think back to Global Winds: The Horse Latitudes
    are located at 30* N and 30* S.
   They are located North and South of the Equator.
   Coordinates tell the actual location of a place.
    30*N, 96*W
   When giving a location on Earth, you give the
    latitude coordinates first and you give the
    longitude coordinates second.
