Answer:
The oceanic plate sinks below the continental plate
Step-by-step explanation:
When there's a collision between an oceanic and continental tectonic plates, we have a convergent plate boundary. The continental plate is less dense, it is higher, and it is thicker, while the oceanic is denser, lower positioned, and less thick. This results in the oceanic plate to sink below the continental plate, in a process known as subduction. As the oceanic plate moves below the continental plate the area around the boundary is lifting up, resulting in the formation of mountain chains. There's also a great deal of volcanic activity along the boundary, often resulting in the formation of volcanic island chains, and the earthquakes are also very common as there's lot of adjustment going on in the crust.
