Which statement correctly contrasts a navigational chart with a land map?

• A. A map shows land features and other information.
• B. There is no difference.
• C. A map is used for navigation with depths and hazards.
• D. A chart is for navigation with depths and hazards; a map shows land features and other information.

Answer: (D)

A navigational chart is built for guiding vessels through waters, so it highlights information needed for safe movement at sea: water depths, hazards to navigation (like rocks, wrecks, or reefs), and navigational aids (lighthouses, buoys, ranges), plus features that help plot courses and avoid danger. A land map, on the other hand, focuses on features on land—terrain, roads, cities, political boundaries, and land use—and doesn’t provide the underwater depths or sea hazards sailors need. So the statement that a chart is for navigation with depths and hazards, while a map shows land features and other information, cleanly contrasts the two tools and is the best description. The other options either claim there’s no difference or misattribute depths and hazards to maps, which doesn’t fit how charts are used.
