Using the outlines from the Mercator and Lambert map projections on the next pages, make the same comparisons among North America, South America, and Greenland. Which is relatively larger and by approximately how many times? Again, describe your observations.
Examples of two cylindrical projections are presented in Figure 4.2, the Mercator projection (conformal, true-shape), and Figure 4.3, the Lambert projection (equivalent, equal-area). These two map projections— the Mercator and the Lambert—are simply being used to examine relative size and shape in each portrayal of Earth.
Trace around the outlines of the same continents and island as indicated above—North America, South America, and Greenland. You might want to mark and color code the tracings according to their source (Mercator or Lambert) for future reference. Use your tracings to answer the following questions. Keep in mind that these two sets of map outlines compared to the globe you used are not at the same scale: the distance measured along their respective equators will not be equal.
Mercator
Lambert
Mercator
approximately same size (Greenland would appear larger if all of Greenland was
shown on map)
Lambert
South America; approximately 5 times larger
