Common Geographic Misconceptions


logo 
The National Geographic has a nice article online titled, "Why Your Mental Map Of The World Is (Probably) Wrong".  According to their article, "These are some of the most common geographic misconceptions that are both surprising and surprisingly hard to correct."    For example, "Most of Africa is north of the equator, though on many mental maps it is mostly in the southern hemisphere directly across the Atlantic from South America."  To see the article click here.
Glen Weibe suggests asking these questions:
Based on your mental (or actual) map of the world, answer a few simple questions:
How much of South America is east of Miami, Florida?
How much of Africa is north of the equator?
Which city is further north – Paris, France or Montreal, Canada?
Venice, Italy is located at the same latitude of what major American city?
Which is bigger? The lower 48 United States or Brazil?

Glen suggests having your students use "The True Size Of" website for the last question.  I have blogged about this map website in March of 2017.  To see that post click here.

He also suggests Bouncy Maps which  "connect locations with data. Maps become bigger or smaller to show differences in the data."  To see Bouncy Maps, click here.

The Mercator Problem

This website explains the problem that happens with the distortion near the poles of this 2 dimensional mapping and this site has an itneractive component.  You can use the dropdowns  to choose two different land masses. You will then be shown the size of each land mass as shown on the Mercator projection and in reality. Compare and contrast the differences.  To see the website click here.
