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 trench.
Challenger deep.
The oceans floor doesn't just keep getting wider instead the ocean floor plunges into deep underwater canyons called deepocean trenches.Where ever deep ocean trenches are there is subduction.
At deep-ocean trenches, subduction allows part of the ocean floor to sink back into the mantle. The ocean floor does not just keep spreading. Instead, it sinks beneath deep underwater canyons called deep-ocean trenches. Where there are trenches, subduction takes place.

Ocean trench is a long, narrow and deep depression in the ocean floor.
The deepest known portion of the ocean floor is called the Challenger Deep, located in the Mariana Trench in the western Pacific Ocean. It reaches a depth of about 36,000 feet (10,972 meters).
