Quizplus · Accepted Answer

The chain of volcanoes that forms at an ocean-ocean convergent plate boundary is referred to as an island arc. These volcanoes are found in a curving line or arc shape above the subduction zone, which is where one of the oceanic plates is subducted beneath the other plate. The volcanic activity that occurs from this subduction creates a chain of volcanic islands.
