one another.
They form a grid
system around
the earth.

Lines of latitude are
also called parallels.
 They circle the earth
parallel to the Equator.
 They measure north
and south of equator in
degrees.
 The Equator is at 0°
latitude.
 The North Pole is at
90°N (north).

 Lines
of longitude are
also called
meridians.
 They circle the earth
from Pole to Pole.
 They measure east
and west of the
starting line, at 0°
longitude or the
Prime Meridian.

 Only

one place can
be found at the point
where lines cross one
another.
 Use degrees (°) and
minutes (’) to give an
exact spot where one
line of latitude
crosses one line of
longitude – an
absolute location.
 The
equator circles the middle of the
Earth.
 It divides the earth into hemispheres or
“half-spheres.”
 North of the equator is the Northern
Hemisphere.
 South of the equator is the Southern
Hemisphere.

 The
Prime Meridian runs from north to
south.
 It divides the earth into half spheres in
the other direction.
 East of the Prime Meridian for 180
degrees is the Eastern Hemisphere.
 West of the Prime Meridian for 180
degrees is the Western Hemisphere.
