What is formed when two tectonic plates collide in an oceanic-continental convergence?

When two tectonic plates collide in an oceanic-continental convergence, the process typically leads to the formation of a mountain range. In this scenario, the denser oceanic plate is subducted beneath the less dense continental plate. As the oceanic plate descends into the mantle, it causes melting and generates magma, which rises to the surface. This volcanic activity can lead to the formation of mountain ranges along the edge of the continental landmass. The Andes Mountains in South America exemplify this dynamic, as they were formed due to the subduction of the Nazca Plate under the South American Plate.

Mid-ocean ridges, volcanic islands, and transform faults are associated with different tectonic interactions. Mid-ocean ridges occur at divergent boundaries where tectonic plates are moving apart. Volcanic islands form in oceanic-oceanic convergence scenarios, where one oceanic plate is subducted beneath another, leading to volcanic activity in the ocean. Transform faults occur where two plates slide past each other horizontally, which does not involve the collision of oceanic and continental plates. Thus, the mountain ranges formed in oceanic-continental convergence are a direct result of the subduction process and the resulting magma that gives rise to volcanic activity,
