Which feature is formed when oceanic plates interact and create volcanic mountains?

• A. Volcanic mountains
• B. Fold mountains
• C. Plateaus
• D. Deltas

Answer: (A)

Volcanic mountains form when oceanic plates interact at convergent boundaries. When one plate is forced down (subduction), the sinking rock melts, creating magma that rises through the crust and erupts as volcanoes. Over time, repeated volcanic events build up mountain ranges of volcanic material along these boundaries, including island arcs. This is the feature described in the question. Other options don’t fit the process: fold mountains come from compression of continental rocks and do not arise from subduction of oceanic plates; plateaus form from extensive lava flows or uplift rather than discrete volcanic peaks; deltas form from sediment deposited by rivers, not from plate tectonics.
