Which term describes the north reference used for maps, navigation, and GPS coordinates?

• A. Geographic north
• B. Magnetic north
• C. Kekule's theory
• D. Uniformitarianism

Answer: (A)

Geographic north is the direction toward the Earth's geographic North Pole and serves as the fixed reference for latitude and longitude. Maps, navigation systems, and GPS coordinates are defined using this true north, along with the prime meridian for longitude. Magnetic north, by contrast, is where a compass points, and it shifts over time and varies by location, which would introduce inconsistency if used as the standard reference. That’s why geographic north is the standard for maps, navigation, and GPS. The other terms refer to unrelated concepts (Kekule’s theory about benzene, and uniformitarianism in geology).
