Divergent boundaries.
trench
An abyss is intense cold, 0.6 C to 3.5 C, no light, and lots of pressure.A trench is a boundary between two lithospheric plates.
spreading
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.
A convergent plate boundary creates a deep ocean trench along the edge of a continent. In this boundary type, an oceanic plate is forced beneath a continental plate, leading to the formation of the trench due to subduction.
this is a convergent boundary
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.
The Mariana Trench is a convergent boundary, specifically a subduction zone, where the Pacific Plate is being subducted beneath the Mariana Plate. This results in the trench being the deepest part of Earth's ocean.

A convergent boundary between a continental plate and an oceanic plate
convergent boundaries are easy to find most of them are found in the ocean. One Famous convergent plate boundary would be the Sunda Double Trench. It is found in the Indian ocean and it reaches a depth of 24,440 feet. It is the deepest trench in the Indian Ocean.
Oceanic-oceanic convergent lead to the formation of Mariana Trench.
