At most convergent boundaries, oceanic plates collide with either another oceanic plate or a continental plate, leading to the formation of ocean trenches. These trenches are deep, narrow depressions in the ocean floor that mark the site of subduction, where one plate is forced beneath another. Additionally, volcanic arcs may form parallel to the trench on the overriding plate due to the melting of subducted material.
convergent
any where
A convergent plate boundary forms a deep sea trench. This occurs when two tectonic plates are pushed towards each other, causing one to subduct beneath the other, creating a trench in the ocean floor.

What causes ocean floor features to form
At an ocean ocean convergent boundary, there will be a formation of volcanoes.
A deep ocean trench typically forms at a subduction zone, which is a convergent plate boundary where one tectonic plate is forced beneath another into the mantle. This process results in the formation of deep trenches in the ocean floor, such as the Mariana Trench in the western Pacific Ocean.

New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
This is known as an accretionary wedge or prism. Please see the related link.
