Latitude

• Lines of latitude are drawn from east-west to
  show distances north or south of the equator.
• 90N (North Pole) is the greatest distance north,
  while 90S (South Pole) is the greatest distance
  south.
• Each line of latitude will run parallel to the
  equator, around the entire world.
• The Equator splits the Earth into two equal parts

Longitude

• Are drawn from north-south from pole to pole to
  show the distances east or west of the Prime
  Meridian (0) which passes through Greenwich,
  England.
• The greatest distance is on the opposite side of
  the globe which is 180 (which is half way around
  the world.
• The Prime Meridian splits the Earth into two
  equal halves.

Hemispheres

• The Equator divides the world into two equal
  halves which are known as the Northern and
  Southern Hemispheres.
• The Prime Meridian and the 180 line of longitude
  split the Earth into two halves, the Eastern and
  Western Hemispheres.
• Each degree () of latitude or longitude is made
  up of exactly 60 minutes () which gives a more
  precise location.

• When reading latitude and longitude your first
  reading will always be so many degrees North or
  South, while your second reading will always be
  so many degrees East or West.
• Latitude and longitude lines will intersect to
  make up a set of coordinates.
• Halifax, 44N,63W will give you the block that
  Halifax is located on a map. N because we are in
  the Northern Hemisphere, and W because we are
  located in the Western Hemisphere.
• To be more specific, we must give the minutes()
  to give an exact location on a map.
• Halifax, 4435N,6340W is an exact location.

Relative vs. Absolute Location

• Relative location of a place is not the exact
  location, but it will give you a general area
  where the place is located.
• For example, Horton High School is located next
  to Highway 101. Think of some on your own ideas
• Absolute location is a specific location, a set
  of coordinates will give you an exact location.
  Rescue centre in St. Johns Newfoundland is
  located at 4735N,5240W. Horton High School is
  located at 75 Greenwich Road South.
• Think of your own examples of absolute location
