Which map is used for navigation in air or water?

• A. Hypsometric Map
• B. Chart
• C. Lithofacies Map
• D. Chorographic Map

Answer: (B)

Navigational mapping is about precision for moving through space in real-time, so the map type used for air or sea travel is designed with explicit navigation information like routes, bearings, scales, and symbols for hazards and aids to navigation. A chart serves this purpose precisely, providing the detailed, standardized data mariners and pilots rely on to determine position, plan courses, and avoid dangers. The other map types desk different tasks: hypsometric maps focus on elevation and relief, lithofacies maps show rock types and depositional environments, and chorographic maps depict the distribution of features across a region but aren’t tailored for navigation. Therefore, for navigating in air or water, a chart is the appropriate choice.
