Transcript Latitude and Longitude

Latitude and Longitude
Latitude
• Latitude lines are imaginary horizontal
lines on a world or large area map.
Latitude lines separate the world into
Northern and Southern hemispheres and
range between 0 degrees at the Equator
and 90 degrees at the North and South
Poles.
Longitude
• Longitude lines are imaginary vertical
lines on a world or large area map.
Longitude lines separate the world into
the Eastern and Western hemispheres
and range between 0 degrees at the
Greenwich Meridian (also known as the
Prime Meridian) and 180 degrees east
and west of Greenwich at the
International Date Line.
• Each degree of latitude and longitude is
subdivided into 60 equal parts called
minutes and each minute is divided into
60 equal parts called seconds. On the
surface of earth, one degree of either
latitude or longitude is about 110 km (69
miles) although it is slightly more at the
poles as the earth is not a perfect sphere.
Latitude and Longitude
• The earth is divided into lots of imaginary
lines called latitude and longitude.
Lines
• Longitude lines run north and south.
• Latitude lines run east and west.
• The lines measure distances in degrees.

Where is 0 degree?
• The equator is 0 degree latitude.
• It is an imaginary belt that runs halfway
point between the North Pole and the
South Pole.

Where is 0 degree?
• The prime meridian is 0 degrees longitude.
This imaginary line runs through the United
Kingdom, France, Spain, western Africa, and
Antarctica.
Latitude & Longitude
Hemispheres
• By using the equator and prime
meridian, we can divide the
world into four hemispheres,
north, south, east, and west.

run across the map
measured in degrees
north and south
of the Equator
they are parallel

Longitude lines
run up and down the
map
measured in degrees
east and west
of the Greenwich
Meridian
they converge at the
Poles
they are all the same
