Which boundary is associated with subduction and is destructive?

• A. Transform boundary
• B. Divergent boundary
• C. Ridge boundary
• D. Convergent boundary

Answer: (D)

Subduction happens at convergent plate boundaries, where two plates push toward each other and the denser plate sinks beneath the lighter one into the mantle. This recycles crust, so it’s considered a destructive boundary. The sinking of crust in these zones creates features like deep ocean trenches, volcanic arcs, and strong earthquakes—classic signs of subduction, such as those around the Pacific Ring of Fire. So the boundary in question is the convergent boundary. Transform boundaries involve sliding past one another with little to no crust destruction, and divergent boundaries move apart, creating new crust rather than recycling it. The term ridge is typically linked to divergent boundaries rather than subduction.
