Question

which type of zone is located at a deep-ocean trench?
○ convergent
○ divergent
○ subduction
○ transform

Explanation:

Deep-ocean trenches form where one tectonic plate is pushed under another. Convergent zones describe plate collision, but the specific zone at the trench where subduction occurs is the subduction zone. Divergent zones create ridges, and transform zones involve sliding plates, not trenches.

Answer:

subduction
