Which of the following is a common geological feature of the ocean floor?

Explanation:
Trenches form where one oceanic plate dives beneath another at subduction zones. The sinking of the denser plate bends the ocean floor and creates a long, narrow, very deep depression that stands out on ocean charts. Because subduction occurs around many boundaries worldwide, trenches are a widespread feature of the ocean floor. They’re among the deepest parts of the ocean and are closely tied to intense earthquakes and volcanic activity nearby. While other features like ridges and abyssal plains exist, trenches are a defining and common sign of how tectonic plates interact at the ocean floor.
