What can occur at a subduction zone?

• A. Volcanoes, trenches, earthquakes
• B. Mountains and rivers
• C. Erosion only
• D. Wind deposition

Answer: (B)

Subduction zones showcase three characteristic features: trenches, volcanic activity, and earthquakes. When one tectonic plate sinks beneath another, a deep ocean trench forms at the boundary. The descending slab releases water into the overlying mantle, lowering melting temperatures and producing magma that feeds volcanoes along a volcanic arc. The intense interaction between plates also causes strong earthquakes. While mountain building can occur from compression and uplift in some regions, rivers are not a direct hallmark of subduction, and erosion or wind deposition aren’t primary tectonic outcomes here. So the best description of what can occur at a subduction zone is the combination of volcanoes, trenches, and earthquakes.
