Lines of Latitude Longitude

1
Lines of Latitude Longitude
2
Lines of Latitude

• Run east to west on the globe
• Starting point is at the equator (0 degrees
  latitude)
• Divide the world into two halves- northern
  hemisphere and southern hemisphere

3
Lines of Longitude

• Run north to south on the globe
• Starting point is the prime meridian (o degrees
  longitude) which runs through Greenwich, England
• Divide the world into two halves the western
  hemisphere and the eastern hemisphere

4
How are they named?

• Given degrees- like a thermometer
• Eg. latitude- 60 degrees N
• Each degree is divided into 60 minutes
• Eg. latitude- 60 degrees, 35 seconds N
• The degrees and seconds describe how far away a
  point on the map is away from the latitude and
  longitude starting points (0 degrees)
• Seconds are named when you are in between 2
  degrees

5
Naming lines on latitude

• Traveling north of the equator the lines of
  latitude increases from 0- 90 degrees north (N)
• Traveling south of the equator the lines of
  latitude increases from 0 90 degrees south (S)
• Eg. St. Johns NFLD is at 47 degrees 35 seconds N

6
Naming lines of longitude

• Traveling east of the prime meridian the lines of
  longitude increase from 0- 180 degrees east (E)
• Traveling west of the prime meridian the lines of
  longitude increase from 0- 180 degrees west (W)
• Eg. St. Johns NFLD is at 52 degrees 40 seconds W

7
Putting it all together

• When describing the location of a place you
  combine the latitude and longitude points to make
  a set of coordinates
• Eg. St. Johns has a set of coordinates of 45
  degrees 35 N, 52 degrees 40 W

8
Absolute Location

• Refers to a specific point on a map
• Described by a set of latitude and longitude
  coordinates

9
Relative Location

• General location on a map
• Described in terms of distance, direction or time
  from another place
• Eg. Annapolis is 25 minutes from Digby
