Answer:
i south American plate(Note that the south american plate has both oceanic and continental plates) convergence with the Caribbean plate
ii Pacific plate converging with the North American plate
iii Pacific and the Mariana plates
Explanation:
Convergent boundaries are boundaries where tectonic plates collides. The plate collision might be between oceanic plate and continental plate, continental and continental plate and oceanic and oceanic plates. Usually, when the continental plate collides with the oceanic plates the more denser plate which is the oceanic plate subduct.
Ocean-ocean convergent boundaries is the collision between oceanic plates.Three different occurrence of ocean-ocean convergence are
i south American plate(Note that the south american plate has both oceanic and continental plates) convergence with the Caribbean plate. The more denser plate subduct after the collision which is the south American plate. The south American plate is more cooler and denser than the Caribbean plate so it will descend beneath the Caribbean plate.
ii Pacific plate converging with the North American plate(oceanic plate section). The pacific plate will descend beneath North American plate because of it denser nature.
iii Pacific and the Mariana plates. The pacific will also be subducted here because Mariana plate is less dense than it and even more buoyant .
The general geologic features/phenomenon found in this kind of boundaries are trenches , Island arc, volcanoes, earthquakes etc
