Which map can be best used for navigation purposes?

1. A Mercator map

2. A thematic map

3. A physical map

4. An economic map

The correct answer is: A Mercator map

The Mercator map is considered the best option for navigation purposes due to its unique projection technique that preserves angles and shapes. This property allows navigators to plot straight-line courses directly on the map using a simple compass bearing. The Mercator projection portrays lines of latitude and longitude as straight, parallel lines, which is essential for maritime navigation, making it particularly useful for sailors who need to navigate using consistent compass directions over vast distances. In contrast, thematic maps focus on specific themes or subjects, such as population density or climate, and do not prioritize navigational accuracy. Physical maps provide a representation of geographical features, such as mountains and rivers, which are useful for understanding terrain but may not offer the precision needed for navigation. Economic maps display data related to economic activities in different regions, which, while informative for socioeconomic analyses, do not serve the practical needs of navigators.
