Final answer:

Closed depressions are shown by hachured contours on topographic maps, while ridges are indicated by elevating contour lines. Understanding these features helps in interpreting topographic maps.


Explanation:

Closed depressions on a topographic map are represented by closed contours with hachures, which are small perpendicular lines inside circular contours. These hachured contours indicate a depression, such as a sinkhole, where the elevation decreases toward the center of the circle. On the other hand, ridges are located where contour lines increase in elevation on either side, forming a higher elevation toward the top of the hill or ridge.
