Identify three (3) different ocean-ocean convergent boundaries. Be sure to indicate which two plates are involved in the collision, and which plate is being subducted. What general geologic features/phenomena are associated with this boundary?

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

these include the fossil fuels, oil, natural gas, and coal and nuclear energy. hope this ! ^.^
