Divergent - where two plates are moving away from one another. (Mid-ocean Ridge)
Convergent - where two plates are moving towards one another. (Ocean Trench) found at both O/O converge and O/C converge.
usually a rift or trench
At a distance of 4100 kilometers on the ocean bottom, you would encounter the Mariana Trench, the deepest known oceanic trench. This trench is located in the western Pacific Ocean, reaching a maximum known depth of about 11,034 meters (36,201 feet) at the Challenger Deep.
the boundary ofthemid ocean ridge is a divergent boundary
The mid-ocean ridge system is the longest continuous divergent plate boundary on Earth.
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust. A classic example is the Mid-Atlantic Ridge where the Eurasian and African Plates are moving away from the North and South American Plates.

Trenches are formed by divergent plates, Whereas Ridges are formed by plate in collision.
usually a rift or trench
Deep Trench in the ocean floor. It can sometimes be mistaken for a mid-ocean ridge.

mid-ocean ridge
A mid-ocean ridge forms at the divergent plate boundary. This boundary initially forms rifts that later on become rift valleys.
The ridge of a trench is typically referred to as the "trench rim" or "trench wall." This elevated area marks the boundary of the trench and can be formed by the accumulation of sediment and debris. In the context of oceanic trenches, the surrounding landforms can include the trench slope and adjacent seafloor features.
