Now look at a globe, which is a model of the Earth.

Find Greenland and Iceland.

On a globe, you can immediately see that the two islands are in the North Atlantic Ocean and are quite close to each other. You can see their size and shape. All kinds of useful information is in front of you. You can see that Greenland is a lot bigger than Iceland. Greenland has a different shape than Iceland. Most of Greenland is above the Arctic Circle, but Iceland is just below it. The longer you look at this model, the more you get a feeling for the differences in the sizes, shapes, and locations of these two islands.

How long did it take? Not long at all. That's the great thing about models. They give lots of information and they give it to you in a way that you can quickly understand.
