subduction of an oceanic plate under a continental plate.
Ocean trenches form at areas of subduction.

An ocean trench does not become a volcanic island, however volcanic islands often form near ocean trenches.
The Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean.

When an ocean plate collides with a continental plate, a subduction zone occurs and forms a deep trench. An ocean plate is more dense while a continental plate is less dense which causes the ocean plate to go under the continental plate and pull the land and water down, forming a trench.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.
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.
well, its the ocean trench. a trench is like a giant ditch and it basically sinks in. while the ocean volcanoes converge and push up.
