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 2 geological features that can occur at plate boundaries?
What are three geographic features that may be found at plate boundaries?
Explain what plate tectonics and ocean trenches have in common?
Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)
What does the theory of plate tectonics suggest about the creation of deep-sea trenches?
They occur where one plate sinks beneath another.
Do trenches occur where plates are moving apart?
yes because the plates are pulling apart from one another which creates a trench
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
When was DeepOcean created?
DeepOcean was created in 1999.
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.
Where do shallow-focus earthquakes of the occur relative to ocean trenches?
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.
Where do ocean trenches occur?
At spreading centers.
What are 2 geological features that can occur at plate boundaries?
What are three geographic features that may be found at plate boundaries?
Do Ocean Trenches Occur where plates are moving apart or where They are moving apart?
at mid ocean ridges
Can earthquakes occur on the coast and by trenches?
Yes, depending whether the main cause was the volcano erupting.
Where does the deepest earthquakes occur?
treches. 300 km or below sea level.
