Which statement about relief is supported by the relationships described for relief characteristics?

• A. High relief features are always the least visible.
• B. Low relief features are typically more visible than high relief features.
• C. High relief features tend to be more visible than low relief features.
• D. Relief does not affect visibility.

Answer: (C)

Relief describes how far a feature stands out from its surrounding surface. When a feature has high relief, it projects prominently, so more of its surface faces light and clearer shadows form along the edges. That combination increases contrast between the feature and the background, making it easier to see. With low relief, the feature sits closer to the plane; light flows over it with less interruption, shadows are subtler, and the feature blends with the surface, reducing visibility. So, in general, high relief features tend to be more visible than low relief features. The other statements contradict how light and shadow emphasize raised details, and relief clearly affects visibility.
