Where in the world is Luxor?

• Use the following maps to
• Estimate Luxors global address using latitude
  and longitude.
• The next 10 slides will help you learn about
  locating areas by latitude and longitude.

Locating Places

• How do you find a city or other location on a
  world map or globe?
• It might be easy to find Dallas, Texas, but what
  if you were asked to find San Miguel, Argentina?
  Where would you begin to look?
• You can find a place more quickly if you
• know its address.
• You can find your seat in the football stadium
• if you know you are sitting in Section 107,
  
• Row M, Seat 9.
• Friends can find your house if they know you
• live at 4120 Viola Drive.

Coordinate System A Grid

• To help us locate places on the earths
  surface, we use a coordinate system.
• This coordinate system is like placing a giant
  grid over the earth. This grid has lines
  extending from east to west (called lines of
  latitude) and lines extending from north to
  south(called lines of longitude).

4
Definitions

• Lines of latitude extend from east to west across
  the Earth. These lines are imaginary. We cannot
  actually see a latitude line on the Earth.
  Latitude is measured both north and south from
  the equator. Latitude is measured in degrees
  ().
• Lines of longitude extend from north to south.
  Like lines of latitude, these lines are
  imaginary. We cannot actually see a longitude
  line on the earth. Longitude is measured both
  east and west from the Prime Meridian. Longitude
  is measured in degrees () . Lines of longitude
  are evenly spaced at the equator, but meet at the
  poles.

LatitudeThe North Pole is at 90
N.L.The South Pole is at 90
S.L.

• 40 N.L. is the 40 line of latitude north of
  the equator.
• 40 S.L. is the 40 line of latitude south of
  the equator.

• The equator is at 0 latitude. It is neither
  north nor south. It is at the center between
  north and south.

EquatorThe equator (0) splits the earth into
the Northern Hemisphere and Southern Hemisphere.

N

• Northern Hemisphere
• Equator
• Southern Hemisphere
• Places located north of the equator have a
  north latitude (N.L.) address. Places located
  south of the equator have a south latitude (S.L.)
  address.

Longitude Lines of longitude begin
at the Prime Meridian.

• 60 E.L. is the 60 line of longitude east of
  the Prime Meridian.

• 60 W.L. is the
• 60 line of
• longitude west
• of the Prime
• Meridian.
• The Prime Meridian is located at 0. It is
  neither east nor west. It is between east
  and west.

Prime MeridianThe Prime Meridian (0) and the
180 line split the earth into the Western
Hemisphere and Eastern Hemisphere. Prime

• Eastern
  Hemisphere
• Places located east of the Prime Meridian
  have an east longitude (E.L.) address. Places
  located west of the Prime Meridian have a west
  longitude (W.L.) address.

• Western Hemisphere

• Mexico is in the Northern Hemisphere because
  it is north of the Equator. Mexico is in the
  Western Hemisphere because it is west of the
  Prime Meridian. Point to the country of Mexico.
