Volcanic arcs and trenches are commonly produced when the oceanic plate bends downwards. For more details, see the following:
When an oceanic plate and a continental plate meet at a convergent boundary, the denser oceanic plate is forced down below the less dense continental plate. This is known as subduction.
This forms a deep trench on the ocean bed and the subducted crust containing high proportions of volatiles (i.e. water) melts as it sinks. This magma forces it's way to the surface forming volcanoes.

As the oceanic plate slides beneath the overriding plate bends what is produced here?
A subduction zone or a trench.
Subduction occurs where the oceanic crust bends down towards the mantle at a?
Subduction occurs where the oceanic crust bends down towards the mantle at a subduction zone, typically at convergent plate boundaries where two tectonic plates collide. The denser oceanic plate is forced beneath the less dense continental plate, creating a deep trench and volcanic activity. This process contributes to the recycling of Earth's crust and the formation of mountain ranges and volcanic arcs.
What happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
Is the Pacific plate and oceanic plate or continental plate?
It is oceanic
When an oceanic plate collides with a continental plate which plate is subducted?
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.

Differences between oceanic-oceanic and oceanic-continental subduction boundary?
In an oceanic-oceanic subduction boundary, one oceanic plate subducts beneath another oceanic plate. This process can result in volcanic island arcs being formed. In an oceanic-continental subduction boundary, an oceanic plate subducts beneath a continental plate. This can lead to the formation of volcanic mountain ranges on the continental plate.
Are subducting plate and oceanic plate the same?
No, subducting plate and oceanic plate are not the same. An oceanic plate is a type of tectonic plate that lies beneath the ocean, while a subducting plate refers to an oceanic plate that is descending beneath another tectonic plate at a convergent boundary. Subducting plates are a specific category of oceanic plates.
What is the motion of plates in a subduction zone?
In a subduction zone, the dense, cold oceanic plate collides with the lighter, warmer continental plate and is forced down underneath it into the mantle. The motion is downwards and the force is called "slab pull".
What form when a oceanic plate collides with oceanic plate?
a trench will form
Is the African plate oceanic?
The African plate is both oceanic and continental.
When a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?
The oceanic plate is denser than the continental plate due to its composition of heavier mafic rock. This density difference causes the oceanic plate to sink below the continental plate in a process known as subduction.
