Mostly at convergent plate boundaries. When one plate is forced under another (a subduction zone) the sinking plate releases water that lowers the melting point of the mantle, producing magma that feeds volcanic arcs, and the compressive forces fold and uplift crust to form mountain belts. Examples: the Andes and the Cascade Range.

Notes:
- Continental‑continental collisions (a type of convergent boundary), like the India–Asia collision that formed the Himalayas, produce large mountains but little volcanism.
- Divergent boundaries (mid‑ocean ridges and continental rifts) also produce volcanic activity (e.g., Mid‑Atlantic Ridge, East African Rift) but different kinds of volcanism.
- Transform boundaries mainly produce earthquakes, not volcanoes.
