Great and Small Circles
SECTION 1
1. Parallels have often been used to demarcate political boundaries. The 49th parallel north forms a por-
tion of the border between which two countries?
The Canada–United States border from Manitoba/Minnesota area to the Pacific Coast.
2. Parallels made famous by wars in the last century include the parallel dividing the two Koreas and the
parallel that divided Vietnam until 1975. (The border was approximately 80 km [50 mi] north of the city
of Hue.) What are these two parallels?
38th and 17th

4. Using a globe and your atlas or other world map, locate three cities that are located at approximately the
23rd parallel in the Northern Hemisphere; note their location in degrees (and minutes, if your map is
detailed enough to estimate minutes). Use the globe first, then refer to the atlas maps to better deter-
mine specific latitudes. Be sure and list their country names as well.
City and Country Name Longitude (degrees and minutes, if possible)
a) Cabo San Lucas, Mexico 109° 55’ W
b) Havana, Cuba 82° 24’ W
c) Guangzhou, China 113° 15’ E

Longitude and Meridians
SECTION 3
1. On a political globe or world map follow the International Date Line across the Pacific Ocean. Why do
you think the International Date Line is not straight but zigs and zags?
The International Date Line zigzags to avoid local confusion. If the Date Line passed through a
country, imagine the confusion of having the country split with each side experiencing a different
day! Political reasons exist as well. The island country of Kiribati moved the International Date
Line to its eastern margin (150° west longitude) to be the first to experience each new day. These
distortions of the IDL only apply to the countries and their territorial waters and not to international
waters between them and the 180th meridian.
2. Examine an atlas or a political globe and in the spaces marked a through h list the provinces and states
through which the 100th meridian in the Western Hemisphere passes—north to south. The first answer
is provided for you in bracketed italics.
a)
b) Manitoba
c) North Dakota
d) South Dakota
e) Nebraska
f) Kansas
g) Oklahoma
h) Texas
3. Figure 1.5 is a view of Earth from directly above the North Pole; the equator is the full circumference
around the edge. A line has been drawn from the North Pole to the equator and labeled 0°, representing
the prime meridian. Earth’s prime meridian through Greenwich, England, was not generally agreed to
by most nations until 1884. To the right of 0° on the diagram is the Eastern Hemisphere, and to the left
of 0° is the Western Hemisphere.
a) Label both the Eastern Hemisphere and the Western Hemisphere.
b) Extend another line from the North Pole to the other side of Earth, opposite the prime meridian,
and label it 180°. You now have marked the line that is the International Date Line, which
extends from North to South Poles on the opposite side of Earth from the prime meridian.
