Geography of the
Non-Western World: GEO 105 Recitation
Lab #1 Map Skills Week of 4/3/00 (due week of 4/10-4/14)
Objective: To become acquainted with Goode's World Atlas, and to
develop some basic map interpretation skills.
Part 1: Getting to know
Goode's World Atlas
There is a wealth of
information in Goode's World Atlas, but first you must know where to find it,
and second, how to interpret it. This part of the assignment will help
familiarize you with the atlas and give you some practice reading information
from maps. You will obtain information from various parts of the atlas, so you
may have to search a little for the answers to some questions. Answer each of
the following in the spaces provided.
1. What cities have the following absolute locations? (Include the
names of countries.)
a. 30° 15' N, 97° 42' W
b. 15° 47' S, 35° 00' E
2. What is the exact latitude and longitude of Corvallis, Oregon, in
degrees and minutes?
3. Use the reference tables at the back of your atlas to answer the
following questions.
a. What are the predominant
languages spoken in Tunisia?
b. How long is the
Tigris River? How does that compare with the length of the Columbia R.?
c. What is the height
of Mt. Rainier? How does this compare with the height of Mt. Everest?
Part 2: Understanding Map
Scale
The scale of a map tells the
reader how large the area represented in the map is compared to the actual size
of the earth. Large-scale maps show small areas of the earth in greater detail,
while small-scale maps show larger areas in less detail. It is important to
understand the concept of scale in order to interpret information from a map.
Answer the following questions in the space provided. For questions involving
calculations, you must show your work to receive full credit.
1. If a map has a scale (representative fraction, or RF) of
1:400,000, one inch on the map represents how many miles on the earth's
surface? Round your answer to the nearest mile. (Hint: First calculate how many inches there are in a
mile.)
2. A map has a scale of 1:400,000. Two places are 5 inches apart on
the map. What is the
distance (in miles) between the places?
3. Listed below are four common map scales. Circle the smallest and
explain why it is the smallest.
1:250,000 1:24,000 1:1,000,000 1:62,500
Part 3: Understanding
the Geographic Grid
It is important to understand
the basics of longitude and latitude in order to locate places on a map, as
well as to refer to general regions of the globe. This section of the
assignment will help you learn the most important parallels and meridians, as
well as perform some calculations involving the grid system.
1. Refer to the following diagram to answer questions a-j. Write the
letter of the correct line of
latitude in the blank next to each term or statement.
___ a. Arctic Circle
___ b. Tropic of Capricorn
___ c. Noon sun is directly overhead
on vernal (spring) equinox
___ d. 23 ½° N latitude
___ e. Equator
___ f. Tropic of Cancer
___ g. Antarctic Circle
___ h. Noon sun is directly overhead
on summer solstice
___ i. 90 N latitude
___ j. 66 ½° S latitude
2. Start with the latitude or longitude listed in the left, then
find the new location by moving the
number of degrees stated.
Example: Lat. 15° S move 35° N new location: 20° N
a. Lat. 55° N move 150° S new
location:______________
b. Long. 120° E move 105° E new location:______________
c. Long. 60° W move 75° W new location:______________
3. a. Since the earth takes 24 hours to make one revolution about
its axis, and since a circle has
360 degrees, how many degrees wide should each one-hour time zone be?
(Show your calculation.)
b. Explain why, in reality, time zones are not of uniform
width, but instead bend and curve around (see p. xii in your atlas.)
