Question

The oceanic nazca plate is being subducted beneath the continental South American plate.what type of plate boundary is this?A)continental-oceanic convergent B)oceanic-oceanic convergent C)divergent D)strike-slip E)transform

Answer 1

You can see with the question alone that the plates involved is a oceanic and continental plate. With just that you can say that the answer is A. Another clue would be the subduction. This means that the plates converged, which makes it the type of boundary that occurred is convergent. 

The answer again is A. 

Answer 2

Answer:

A)continental-oceanic convergent

Explanation:

The convergent oceanic-continental boundary occurs when a collision occurs between an oceanic plate and a continental plate, as with the nazca ocean plate being subdivided below the South American continental plate. The result of this is the formation of a subduction zone, since the oceanic plate is heavier and ends up below the continental plate.
