Convergent: This is when two plate tectonics move towards each other. They are crashing into one another and this causes for one of the plates, normally the oceanic crust, to go under the other. This is called subduction. In this areas normally there is a lot of destruction like earthquakes and volcanoes.
Mid-Oceanic ridge: This are the mountain ranges that spread across the ocean floor. It is produced by a convergent boundary.
Subduction: This is the process were the edge of one crustal plate is forced below the edge of another.
Orogenesis: This is the process of mountain formation due to the engagement of tectonic plates.
Continental Volcanic Arc:A continental volcanic arc is a chain of volcanoes positioned in an arc shape as seen from above. It is formed when the oceanic crust is forced beneath the continental crust on an adjacent plate, creating an arc-shaped mountain belt.
Volcanic Island Arc: It is a chain of volcanoes that are in an arc shape that can be seen from above. These occurs between two converging tectonic plates, most of the time it is when one oceanic plate subducts another plate.
