Convergent oceanic-continental boundary
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.
A convergent plate boundary. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary.
The mantle convection currents beneath a continental convergent boundary will heat up and rise. They are heading toward each other, therefore, causing the two continents to collide.
Subduction is when one of the plates is forced down beneath the other plate at the convergent boundary.

The western coast of South America is a very good example of an oceanic to continental convergent boundary where the Nazca plate is colliding (and being subducted beneath) the South American plate.
Convergent plate boundaries can occur as a continental-continental, continental-oceanic, or oceanic-oceanic crust collision. A continental-continental collisions will typically result in a mountain range formation, such as the Himalayan Mountain Range. A continental-oceanic converging plate boundary will result in the more dense oceanic crust subducting beneath the less dense continental crust. The subduction zone leads to volcano formation from melting rock within the asthenosphere, beneath the continental crust. An example of this boundary is the west coast of the United States. An oceanic-oceanic converging plate boundary will typically result in one oceanic slab "sliding" beneath the other, due to only slight differences in density. This may form a volcanic island arc on the ocean floor, but may not necessarily reach above sea level.
The type of boundary that forms when the crust of one plate is pushed down under another plate and turned into molten rock is referred to as a convergent boundary. Convergent boundaries form when oceanic crust slides beneath continental crust.
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
