what type of convergence are the andes mountains
Answered by The Community. Making the world better, one answer at a time. The type of boundary that the Andes mountains are, in South America, is a convergent plate boundary. This was formed from the collision of the South American plate boundary and the Nazca plate.his is when plates move toward each other. more specifically the type of plate collision that caused the Cascad â¦ es is an oceanic-continental convergence. This is when a plate with continental leading edge slowly collides with a plate that has an oceanic leading edge.
