Why does deep-ocean trench occur?
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.

What are deep-ocean trenches?
Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin
What happens at deep-ocean trenches?
subdution
What is deep holes in the ocean floor called?
trenches
Do the ocean has mountains and valleys?
Yes the ocean floor has mountains and deep trenches.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
What happens when continental and continental collide?
Deep ocean trenches form
What is a valley underwater called?
The Marianas Trench, and many other deep undersea valleys, can be found on the ocean floor.
Are older rocks on the ocean floor found near deep sea trenches?
Yes
What is a deep crack in the ocean floor?
huge cracks in the ocean floor are called trenches.

what other ocean floor feature is fromed by movement of earth's plates
