What term describes the area around one of the poles?

• A. The Age of Discovery
• B. Astrolabe
• C. Mesa Verde
• D. Circumpolar

Answer: (D)

Circumpolar describes the region around one of the poles. In geography and astronomy, it designates the zone that lies around either pole—within the Arctic Circle or the Antarctic Circle—where the pole itself dominates the sky and daylight patterns, such as the midnight sun in summer or polar night in winter. The name literally means surrounding the pole, which is exactly what this term conveys. The other options refer to unrelated topics—an era of exploration, a navigation tool, and a historic site—so they don’t describe a polar region.
