Which world map projection is known for preserving direction well but distorts the size of land near the poles?

• A. Peters Projection
• B. Mercator Projection
• C. Robinson Projection
• D. Equal-area Projection

Answer: (B)

Preserving direction well is a hallmark of conformal projections, which keep local angles intact. The Mercator projection is the classic example: it preserves shapes and directions locally, so a course of constant bearing appears as a straight line—great for navigation. The trade-off is dramatic distortion of size toward the poles, since the map must stretch distances more and more as latitude increases. That’s why landmasses near the poles look much larger than they actually are. In contrast, an equal-area projection preserves land area but not direction or shape, the Peters projection emphasizes area, and the Robinson projection is a compromise that softens distortions in all directions. So the map that best fits “preserves direction well but distorts size near the poles” is the Mercator projection.
