Question

What features are likely to form where the Australian and Pacific plates meet? Select ALL that apply.

Group of answer choices

earthquakes

island arcs

deep-sea trenches

mid-ocean ridges

Answer 1

- earthquakes
- island arcs
- deep-sea trenches

Reason: Much of the Australia–Pacific plate boundary is convergent/subduction and transcurrent, producing subduction-related deep trenches and volcanic island arcs, and frequent earthquakes. Mid‑ocean ridges form at divergent boundaries, so they do not generally occur there.
