Two differences between a chart and map (map)

• A. Not meant to be drawn on and shows topical land masses
• B. Shows harbors, ocean contours and channels, and meant to be written on
• C. Is decorative only
• D. Has no navigational use

Answer: (A)

The key idea is that nautical charts and general maps serve different purposes. A chart is a specialized navigation tool for use at sea, focusing on the water area near coastlines and showing only the land features that matter for safe passage. It highlights navigationally relevant land masses and coastlines, and the chart itself is not intended as a general drawing surface for unrelated markings. This makes it uniquely suited to plotting courses, understanding depths, and avoiding hazards in the watery environment.

In contrast, a general map is a broader representation of the Earth's surface, typically with a wider focus on land features and geography, and it is commonly used as a writable reference for various purposes. The option that describes a chart as not meant to be drawn on and that it shows topical land masses captures the distinction: charts are designed for navigational use near water and exhibit land features only insofar as they affect navigation, while maps are broader and more flexible for general purposes.
