Explain THREE (3) differences between nautical chart and map.

Purpose: The primary difference between a nautical chart and a map lies in their purpose. A nautical chart is specifically designed for navigation by water, providing information about water depths, shoreline details, hazards, tides, currents, and aids to navigation like lighthouses and buoys. On the other hand, a map is a general representation of an area's physical and man-made features, used for a variety of purposes, such as driving, hiking, or planning construction.

Information Presented: Nautical charts and maps present different types of information. A nautical chart includes details relevant to marine navigation such as sea bed composition (sand, mud, rock), magnetic variation, shipping routes, and restricted areas. A map, however, may include details like roads, buildings, parks, political boundaries, and topographic features like mountains and valleys.

Scale: Nautical charts are usually drawn at larger scales than maps. This means they show a smaller area in greater detail, which is crucial for safe navigation in marine environments. Maps, on the other hand, often cover larger areas at smaller scales, providing a broader overview of a region or country.
