What is a key characteristic of minor terrain features?

A key characteristic of minor terrain features is that they are typically less prominent than major features. Minor terrain features can include things like small hills, depressions, or slight changes in the landscape that do not stand out as distinctly as major features such as mountains or large rivers.

While minor features are valuable for navigation and situational awareness, they do not command the same level of attention or recognition as major features. Their subtlety means they can often blend into the surrounding environment, which necessitates careful observation and understanding from pilots when navigating. This contrasts with major terrain features, which are usually larger and more easily identifiable, thereby serving as significant landmarks in flight operations.

The other characteristics in the options do describe elements associated with terrain features but do not specifically relate to the defining nature of what makes a feature 'minor' compared to 'major' features.
