Question 176Navigation General70% to pass

On U.S. charts, you can tell if a named feature such as a rock (i.e. Great Eastern Rock in Block Island Sound) is submerged by the _______________.

AI Explanation
The correct answer is C) style of type used to print the name. On U.S. nautical charts, the style of type used to print the name of a feature indicates whether it is submerged or not. Specifically, a feature printed in regular (upright) type indicates that it is above the water, while a feature printed in italicized (slanted) type indicates that it is submerged. This is a standardized cartographic convention used on U.S. charts to convey the status of charted features. The other options are incorrect because they do not accurately reflect the way submerged features are depicted on U.S. nautical charts. The color of the ink, dashed circles, and magenta circles are used for other purposes, such as indicating depth contours or underwater obstructions, but they do not specifically denote whether a named feature is submerged or not.
