Parallels of Latitude• Latitude measures angular distance North or South of
the Earth’s Equator, in degrees, minutes, and seconds.• Latitude is represented by horizontal lines on a map.• The Earth’s Equator is zero (0°) degrees latitude, the
North Pole is 90 degrees North latitude, and the South Pole is 90 degrees South latitude.
Equator: 0°
North Pole: 90° North
Other parallels of latitude
Lines of Longitude• Longitude measures angular distance East and West,
in degrees, minutes, and seconds.• Longitude is represented by vertical lines on a map.• Long ago, people agreed to use the line of longitude
that runs through Greenwich, England, as zero degrees (0°). All other lines of longitude are either East or West of 0°, and go to 180° in each direction.• Lines of longitude are like sections of
an orange; they meet at the poles.
