Which projection maintains overall shapes and relative positions without extreme distortion?

• A. Mercator Projection
• B. Robinson Projection
• C. Polar Projection
• D. Gnomonic Projection

Answer: (B)

Maps try to translate a round Earth onto a flat surface, and every projection introduces some distortions. The best choice for keeping the overall look of the continents and their locations without dramatic distortion is a compromise projection. The Robinson projection was designed to balance distortions in shape, area, distance, and direction across the whole globe, so landmasses appear with fairly recognizable outlines and their relative positions are preserved without the extreme stretching or squashing you see in other projections. It doesn’t perfect any one property, but minimizes noticeable distortions globally, making it a good general-purpose world map. By contrast, a Mercator projection preserves shapes locally but inflates sizes toward the poles; a Gnomonic projection highlights great-circle routes as straight lines but distorts most of the map; and a polar-centered projection focuses distortion around the opposite regions, not giving a balanced view of the entire world.
