MAP READING
Latitude and Longitude
LATITUDE
Imaginary lines running East/West
Measure North/South of the Equator (0o)
Splits Earth into Northern/Southern hemisphere
Called parallels
North Pole = 90o N
South Pole = 90o S
Parallels are spaced 111km apart
LATITUDE CONT.
LONGITUDE
Imaginary lines running North/South
Measure East/West of the Prime Meridian (0o)• Prime Meridian = Greenwich, England
Splits Earth into Eastern/Western hemisphere
Called meridians
Numbered 180o both East and West from Prime
Meridian (0o)• 180o = International Date Line
LONGITUDE
PRIME MERIDIANThe Prime Meridian (0o) and the International Date
Line (180o) split the Earth into the Eastern and
Western hemisphere
Places located East of the Prime Meridian have an Eastern
(E) longitude; places located West of the Prime Meridian
have a Western (W) longitude.
By combining latitude and longitude, any location
can be pinpointed.
A location’s coordinates:• ( ____o N or S, ____o E or W)
APPLICATION
North America is in the Northern Hemisphere because it
is North of the Equator. North America is in the Western
Hemisphere because it is West of the Prime Meridian.
