Convergent plate boundaries produce several key features, depending on the plate types involved:
- Oceanic‑continental convergence: deep ocean trench at the subduction zone and a volcanic mountain range on the continent (e.g., the Andes). Subducting oceanic slab melts and drives continental volcanism; compression uplifts mountains.
- Oceanic‑oceanic convergence: deep trench plus an island arc of volcanoes (e.g., the Mariana Islands and Mariana Trench).
- Continental‑continental collision: large folded and faulted mountain ranges (e.g., the Himalayas) formed by crustal thickening and uplift (little volcanism because neither slab readily subducts).
So the common features are trenches, volcanic arcs, and mountain ranges, depending on which plates collide.
