Why do all maps experience some degree of distortion?

All maps experience some degree of distortion because they represent the Earth's three-dimensional curved surface on a two-dimensional flat surface. This fundamental difference in geometry means that when the Earth's features—like continents, oceans, and countries—are projected onto a flat map, some distortion is inevitable.

Aspects such as area, shape, distance, and direction may all be affected in various ways, depending on the type of map projection used. For instance, commonly used projections, such as the Mercator, maintain the shape of landmasses but distort their sizes, particularly near the poles. Conversely, other projections might accurately depict area but alter shapes or distances. Understanding this concept is crucial for evaluating the utility and applicability of different maps for various geographic analyses.

The other options do not accurately describe why distortion occurs. A flat earth surface misrepresents the situation, as the Earth is indeed curved. The claim that maps are created without a scale overlooks the fact that most maps do include scale, which relates to measurement rather than distortion. Lastly, the consideration of elevation is separate from the core issue of how a three-dimensional object is represented in two dimensions.
