Longitude and meridians

  1. List two advantages that a globe has compared to a map.

Figure 6 Mercator, Peters, and Goode’s projections


  1. The Mercator projection (conformal cylindrical equatorial) maintains the correct shape of landmasses, but not

their sizes. As a result, Greenland (0.8 million square miles) appears larger than the entire continent of Africa

(11.6 million square miles). The Peters projection (equal area cylindrical equatorial) maintains the correct size of

countries, but not their shapes. Goode’s projection maintains the size and shape of landmasses, but interrupts

the oceans. Are you more accustomed to viewing one of these in particular? How do these maps influence your

perception of the world?

  1. Take a look through pages 12-13 in Goode’s World Atlas (if you have the 23rd edition, pages xvi and xvii). These

pages describe and show examples of the main map projections used in the atlas. List one benefit and one

drawback specific to Goode’s Interrupted Homolosine Equal Area Projection (also shown above in Figure 6).

  1. What is a map projection?

Types of Maps

Look over the thematic map types on pages 14-15 (or xviii-xix in newer edition) and types of map projections on pages

12-13 (xvi and xvii) in Goode’s World Atlas to answer the following:

  1. What type of thematic map are the temperature maps on pages 32-33 (or in 23rd edition, pages 22-23)? Select

one of the following:

a. Choropleth map

b. Isoline map

c. Area class map

  1. On page 39 (or page 30 in 23rd edition), examine the map of carbon dioxide emissions.

a. What type of thematic map is this?

b. What does the size of the circle represent?

c. What does the color of the circle represent?


  1. On the Rock Type map pp. 96-97 (or in 23rd edition, the Geology map on pages 42-43), would the Colorado

Plateau appear larger or smaller at a scale of 1:1,000,000?

  1. Looking at the Rock Type of the US map on pages 96-97 (42-43 in newer edition), can you discern which rock

type is more common at the surface (igneous, metamorphic, or sedimentary)?
