1. Why is the Mercator map projection especially useful for navigation on the surface of the earth?
Distortion of shape is minimized
b. Direction is constant across the map
Distances are correctly portrayed
d Area of land masses is shown correctly
e. It shows the sizes of bodies of water realistically

b. Direction is constant across the map.

Explanation:

The Mercator map projection is a cartographic chart of the Earth's surface. It was produced by Gerardus Mercator in 1569. This map shows the distances between the meridians in straight lines but creates distortions when the marked lines approach the poles due to the map's poor ability to resemble the actual shape of the earth.

However, these straight and uninterrupted lines allow the production of constant nautical charts for maritime navigation. Therefore this map has been used over the years.
