Ocean ridges and deep ocean trenches force slab pull and slab push to facilitate plate tectonics. The ocean ridges raise the ocean floor pushing the plate toward the trench, which is lower pulling the plate into the subduction zone.

What are Deep underwater canyons called?

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.

within or adjacent to trenches


Do trenches occur at divergent boundaries?

that is false


Do Trenches occur at divergent plate boundaries.?

that is false


Why does an ocean trench occur?

oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.


What are 2 geological features that can occur at plate boundaries?

Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.


Where does the deepest earthquakes occur?

treches. 300 km or below sea level.


Can earthquakes occur on the coast and by trenches?

Yes, depending whether the main cause was the volcano erupting.


Do Ocean Trenches Occur where plates are moving apart or where They are moving apart?

Ocean trenches occur where plates are moving towards each other and one plate is being pushed beneath the other in a process called subduction. Trenches are formed at convergent plate boundaries where oceanic crust is being forced downward into the mantle.


When and where the trench occurs?

Trenches occur by diverging plate boundries and normally at about 11,000 meters deep. This includes sea floor spreading which is where a new layer of crust forms at the mid ocean ridge and the old crust falls into trenches


Where do ocean trenches occur?

At spreading centers.
