Question

Which of the following ocean-floor features is associated with trenches?

Abyssal plain

Guyot

Mid-ocean ridge

Subduction zone

Answer 1

Earth sci is not my strong point, but after looking and reading around, I believe the answer is subduction zone. One plate is being pushed under the other to create the trench....

Here's some more support:
The Mariana Trench is part of the Izu-Bonin-Mariana Arc geological boundary system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted beneath the smaller Mariana Plate that lies to the west

Hope that helped!
