It is called a destructive plate boundry...one type of crust is oceanic and the other is continental. when they meet the oceanic crust gets pushed down as it is heavier. the friction caused when it sinks creates huge earthquakes and the crust re-melts and gets forced upwards due to pressure to form a volcano.
Oceanic to oceanic- one plate sinks under the other Oceanic- Continental ocean crust sinks under the other
Its when the oceanic crust and the continental crsut colide together.
when 2 oceanic plates move toward(converge)each other they form a lain of VOLCANIC ISLAND ARC.when 2 continenatl plates move toward(converge)each other they form MOUNTAIN BUILDING.
A convergent boundary of two plates will push together. If it is two continental crusts, then they will both push upward, forming mountains. If it is a continental crust pushing against an oceanic crust, then the oceanic crust will go underneath, melt, and be recycled because the oceanic crust is less dense than the continental crust.
oceanic
A destructive margin is when the oceanic crust moves towards the continental crust and slip under it (oceanic crust is heavier than the continental crust). This can build up a lot of pressure between the plates.

oceanic
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
Oceanic Crust
Continental crust (Eurasian Plate) and oceanic crust (pacific plate) move towards each other, oceanic crust sinks because its denser, this forms deep sea trenches and volcanoes
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
The 3 general types are constructive, destructive, and conservative boundaries. Constructive (divergent) - plates move away from each other, typically creating a rift Destructive (convergent) - one plate will be subducted, or continental plates collide Conservative (transform) - plates grind past each other, stalling and slipping
