Which relief is shallower and does not emerge with as much definition from the background plane?

• A. High relief
• B. Low relief
• C. Revetment
• D. Rotunda

Answer: (B)

Depth in relief sculpture determines how much forms stand out from the background. A shallow depth produces a subdued emergence from the plane, which is characteristic of low relief (bas-relief). In low relief, figures barely rise from the background and light mostly skims the surface, giving limited definition. High relief, by contrast, involves deeper carving so the shapes project more and cast strong shadows, becoming more defined from the background. Revetment is a wall-facing treatment, not a type of relief, and rotunda refers to a circular building, not to relief depth. So the shallower emergence described points to low relief.
