That's because it's wrong data! I checked the source, it's a very suspicious website. Even if you look into a map, you can clearly see that the Colombia-Venezuela or Niger-Nigeria borders are larger. Besides that big mistake, great quiz!

It might be worth mentioning in the instructions that borders can be broken - for example, Russia-China is broken in two by Mongolia, and the 3,645 km is the aggregate of the two lengths.

+1
Level 51
Jul 23, 2021
Rivers/terrain vs straight lines. Rivers and terrain meander which makes their lengths significantly longer than they appear.

There are quite a few comments above re Norway/Sweden... something one would only think if one uses a Mercator map. Out of interest, do any of your school systems still use the Mercator projection? I know the US school system still does, but am curious of any others.
