Which of the following is NOT a major terrain feature found on a map?

A cliff is indeed a significant geographic feature, but it is typically considered a minor terrain feature on a topographic map compared to hills, valleys, and ridges, which are classified as major features. Major terrain features can be defined as those that are easily recognizable and typically have prominent characteristics that influence movement, navigation, and strategic planning in military operations. Hills rise above the surrounding terrain, valleys are low areas often between hills or mountains, and ridges are elongated elevations that typically offer a higher strategic position. In contrast, a cliff is a steep face of rock or earth that, while certainly notable, does not serve the same tactical significance in the context of major terrain features and is more often classified under minor features. Therefore, identifying the cliff as not fitting the category of major terrain features aligns correctly with military map interpretation principles.
