Which term corresponds to a two-dimensional representation of Earth's surface?

• A. Terrestrial Globe
• B. Map
• C. Globe
• D. Cartography

Answer: (B)

A flat depiction of Earth's surface is a map. Maps take the curved surface of the planet and project it onto a flat plane, which is why you see features like continents, roads, and boundaries laid out on a two-dimensional sheet with symbols and scale. Because projection from three dimensions to two inevitably distorts some properties, different map types optimize for different goals, trading off accuracy in shape, area, distance, or direction depending on purpose. A globe, by contrast, is a three-dimensional model that preserves shapes and relationships more naturally without projection distortion, though it’s not flat. The term cartography refers to the science and art of making maps, not the representation itself. So the two-dimensional representation described here is a map.
