Deep-ocean trenches are most abundant around the rim of what plate?

There are no deep ocean trenches formed by subduction zones; instead, the European, Asian, and North American plates are moving eastward and westward, forming the divergent boundary that forms the Atlantic Ocean.

The expanding Pacific Crust meets the North American, South American, and Asian Crusts to form subduction zones, which are formed when the Pacific Crust is pushed under the colliding continental crusts. The subduction zones create the deep ocean trenches. The Pacific Ocean is formed by a divergent boundary, but unlike the Atlantic Ocean crust, the Pacific Plate is not connected to any continental crust.

The deep ocean trenches are formed by subduction zones that are created when the Pacific Ocean and continental crusts collide.
