Longitude
Lines of Latitude
Run east to west on the globe
Starting point is at the equator (0
degrees latitude)
Divide the world into two halvesnorthern hemisphere and
southern hemisphere
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
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
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. John’s NFLD is at 47 degrees
35 seconds N
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. John’s NFLD is at 52 degrees
40 seconds W
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. John’s has a set of
coordinates of 45 degrees 35’ N, 52
degrees 40’ W
Absolute Location
Refers to a specific point on a map
Described by a set of latitude and
longitude coordinates
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
