Which term refers to a facing of impact-resistant material that protects a structure?

• A. Low relief
• B. Revetment
• C. Rococo
• D. Underglaze painting

Answer: (B)

A protective facing of impact-resistant material that shields a structure is revetment. This term describes a facing—often of stone, concrete, or other sturdy material—placed on the exterior to absorb shock, prevent erosion, and reduce damage from blasts, projectiles, or moving water. In engineering and fortification contexts you’ll see revetments on sea walls, riverbanks, and fortified walls, where the outer layer takes the hit to protect what’s behind it. The other terms refer to quite different ideas: low relief is a shallow sculpture technique where forms project slightly from a background; Rococo is an ornate 18th‑century decorative style; underglaze painting is a ceramic decoration method applied before glazing.
