Question

what does an oceanic - oceanic convergence give rise to?
volcanic island arcs
valleys and ridges
continental volcanic mountains
folded mountains

Explanation:

Oceanic - oceanic convergence occurs when two oceanic plates collide. The denser plate subducts beneath the less - dense one. As the subducting plate descends into the mantle, it melts due to increased temperature and pressure. The magma then rises to the surface, forming volcanic island arcs. Valleys and ridges are more associated with mid - ocean ridges (divergent boundaries). Continental volcanic mountains are formed at oceanic - continental convergence. Folded mountains are formed at continental - continental convergence.

Answer:

volcanic island arcs
