Which map shows land or submarine bottom relief in terms of height above a datum, with contours, hachures and shading?

• A. Chorographic Map
• B. Hypsometric Map
• C. Bathymetric Map
• D. Chart

Answer: (B)

Hypsometric maps convey vertical relief by height relative to a fixed datum, usually mean sea level, and use contour lines, hachures, and shading to show how the terrain rises or falls. This approach can depict both land elevations and submarine bottom relief when depths are measured from the same datum, giving a uniform sense of height above that reference level. The contours provide exact elevation values, hachures hint at the direction and steepness of slopes, and shading adds a three-dimensional feel to the terrain, making the relief easy to read at a glance. Other types don’t combine these features to represent elevation and depth in the same integrated way: chorographic maps focus on general geographic features without elevation cues; bathymetric maps emphasize underwater depths but aren’t framed in terms of height above a datum with the same contour-hachure-shading presentation; and charts are primarily navigational and not designed to show broad relief.
