What type of geological feature is typically associated with oceanic-continental convergence?

In oceanic-continental convergence, the oceanic plate is denser than the continental plate and is forced down into the mantle in a process known as subduction. This subduction creates a zone of tectonic activity that is prominently associated with volcanic arcs. As the oceanic plate sinks and melts, the resulting magma can rise through the continental crust, leading to the formation of volcanoes. These volcanic arcs are typically found parallel to the coastline of the continent adjacent to the subduction zone, highlighting the direct link between the convergence of these two plates and volcanic activity.

Rift valleys, plain regions, and plateaus do not reflect the geological processes specific to this type of convergence as they are associated with different tectonic dynamics, such as divergent boundaries and uplift processes elsewhere in the geological landscape. Thus, the formation of volcanic arcs stands out clearly as a defining feature of oceanic-continental convergence.
