What term describes the method of representing the curved surface of the Earth on a flat map?

• A. Grid
• B. Projection
• C. Legend
• D. Map Scale

Answer: (B)

Representing the Earth's curved surface on a flat map is achieved through projection, the method of transferring a 3D globe onto a 2D plane. A projection explains why maps inevitably distort some properties—area, shape, distance, or direction—because you can’t perfectly flatten a sphere. Different projections prioritize different qualities depending on purpose; for example, some preserve shape well, while others keep area more accurate. The other terms refer to map features, not the method of transformation. A grid is the network of latitude and longitude lines used for locating places. A legend explains symbols and colors. Map scale shows how map measurements translate to real-world distances.
