Question

Which of the following geological features forms at a subduction zone between an oceanic and a continental plate?
Question 14 options:

A)

The lithosphere

B)

Mid-ocean ridge

C)

Continental shelf

D)

Magnetic anomalies

Answer 1

Answer: C) Continental shelf

Explanation: At an oceanic–continental subduction zone the oceanic plate is forced under the continent, producing a trench and a continental volcanic arc and typically a narrow continental shelf at the active margin. Mid‑ocean ridges and magnetic anomaly striping form at divergent (spreading) boundaries, and the lithosphere is the plate itself rather than a feature produced by subduction.
