Distortion: The Big Problem with Maps

Maps are great tools, but they’re not perfect pictures of Earth’s surface. Maps are 2- dimensional or flat Earth is 3-dimensional and shaped like a sphere.

The only way… The only way to show a spherical Earth on a flat map is by stretching some parts of it. DISTORTIONThis changes the shape, size, and position of Earth’s features. These changes are called DISTORTION

How to Deal with Distortion

One way geographers deal with the problem of distortion is to use globes. Globes are better models of the whole Earth than flat maps. Globes show the size, shape, distance and direction of places on Earth very accurately. Unfortunately, globes cannot show a lot of detail without becoming huge. Solution 1 Solution 1:

Maps, in contrast, can show smaller areas of Earth and include much more detail. Maps are much easier to carry around!

Solution 2: Use map projections. Map projections is a particular way of showing Earth on a flat surface. All map projections have some kind of distortion. For example, one projection that accurately shows the sizes of places will distort their shapes.
