S south
E
east
W west
2. Intermediate Directions
NW northwest
NE northeast
SW southwest

Map Key explains symbols, lines, colors on
a map.
Scale
• A map’s scale compares the distance on a
map to the distance in the real world.
• Scale helps find the distance between two
places.
• There are large-scale maps and smallscale maps.
Hemispheres
• Hemi- means "half" and sphere means
"globe."
• The earth is not really broken into halves,
but there are imaginary lines used by
people to divide the earth into different
sections, called hemispheres. Just like
with compass directions, these sections
help to describe where you are on the
earth.
Imaginary Lines
Latitude-imaginary lines that run east and west
around the earth.
Equator- the beginning latitude line with a
measurement of 0.
Lines below the Equator are measured in degrees
and said to be south of the Equator.
Lines above the
Equator are measured in
degrees and said to be
north of the Equator.
The North Pole and the
South Pole are the last latitude
measurement. 90 degrees
• Longitude- imaginary lines that run north and
south around the earth.
• Prime Meridian- the beginning longitude line with
a measurement of 0.
• Lines to the left of the Prime Meridian is
measured in degrees and said to be west
of the Prime Meridian.
• Lines to the right of the Prime Meridian is
measured in degrees and said to be east
of the Prime Meridian.
• The International Dateline is the last
longitude line with a measurement of 180
degrees.l
• Latitude and longitude lines are used to
help locate specific places on the earth.
