What geographic term refers to changes in shape, size, or position when depicting the Earth on a flat map?

• A. Scale error
• B. Projection error
• C. Map distortion
• D. Cartographic generalization

Answer: (C)

Map distortion is what happens when a curved surface like the Earth is laid out on a flat map. Because a sphere and a plane cannot be perfectly matched, converting from globe to map inevitably changes some properties. Distortion can affect shape (angles and outlines), size (area), or position (relative locations and distances) depending on the chosen projection. Different projections trade off these distortions in different ways—one might preserve shapes locally but stretch areas, while another might preserve areas but alter shapes. That broad concept is what the term map distortion captures.
