Which surface feature is a representative example of a convergent boundary?

• A. Volcanic arcs and trenches
• B. Mid-ocean ridge
• C. Rift valley
• D. Transform fault

Answer: (A)

Convergent boundaries are where plates collide and one sinks beneath the other in subduction. This process creates deep trenches at the boundary and drives melting in the overlying mantle, producing magma that forms volcanic arcs on the overriding plate. So, volcanic arcs and trenches are the classic surface features signaling convergence. The other features come from different boundary types: mid-ocean ridges form where plates pull apart (divergent), rift valleys also arise from divergence, and transform faults accommodate lateral slide without subduction or trench formation.
