At an oceanic-continental convergence boundary, the oceanic plate is typically subducted beneath the continental plate. This process can lead to the formation of deep oceanic trenches, volcanic arcs on the continental plate, and strong earthquakes due to the intense pressure and friction. Over time, sediment may accumulate on the continental plate as a result of subduction and mountain building.

Oceanic-continental convergence occurs in regions where an oceanic plate is subducting beneath a continental plate. Examples of this type of convergence can be found in various locations around the world, such as along the west coast of South America in countries like Chile, Peru, and Ecuador, as well as in regions like the Andes Mountains.

A subduction plate involves an oceanic plate being pushed beneath a continental plate or another oceanic plate. The oceanic plate is denser and sinks into the mantle at a convergent boundary, creating a subduction zone. Common examples include the Pacific Plate subducting beneath the North American Plate along the west coast of North America.
An oceanic-continental convergence typically results in the oceanic plate subducting beneath the continental plate due to its higher density. This can lead to the formation of volcanic mountain ranges on the continental plate, as magma generated by the subducted plate rises to the surface and forms volcanoes. Additionally, intense seismic activity and the potential for tsunamis can also be associated with this type of plate boundary.
In oceanic-continental convergence, the denser oceanic plate is forced beneath the continental plate in a process called subduction. This creates a deep ocean trench and can lead to volcanic activity and the formation of mountain ranges on the continental plate. The collision can also cause earthquakes.
The Andes mountain range was not formed as a result of continental-continental convergence; instead, it resulted from oceanic-continental convergence. Specifically, the Andes were created by the subduction of the Nazca Plate beneath the South American Plate. In contrast, the Himalayas, Alps, and Appalachians are primarily the result of continental-continental tectonic interactions.
