Ocean trenches occur at convergent plate boundaries, where two tectonic plates are colliding. The denser oceanic plate is forced beneath the less dense continental plate, creating a deep trench in the ocean floor. Examples of ocean trenches include the Mariana Trench in the western Pacific Ocean and the Peru-Chile Trench off the coast of South America.
Deep sea trenches occur at convergent boundaries when one tectonic plate is pushed beneath the other tectonic plate. This process is called subduction. The previous answer was incorrect because they were explaining how mid ocean ridges form, not trenches.

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.
What do earthquakes volcanoes mineral deposits ocean trenches and mountain ranges all have in common?
they all occur along plate boundaries
What are the valleys under the ocean called?
They are called trenches.
In which ocean basin are most trenches found?
Most trenches are found in the Pacific Ocean basin. This is because the Pacific Plate is the largest tectonic plate on Earth and is actively subducting beneath other plates, leading to the formation of deep ocean trenches. The Mariana Trench, the deepest trench in the world, is located in the Pacific Ocean.
What results from a convergent boundary?
A convergent boundary results in the collision of two lithospheric plates, leading to the formation of mountains, deep ocean trenches, and volcanic activity. Subduction zones can also occur, where one plate is forced beneath the other into the mantle.
Where do shallow-focus earthquakes of the occur relative to ocean trenches?
within or adjacent to trenches
Why does an ocean trench occur?
oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.
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 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.
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:)
How many trenches does the Atlantic ocean have?
there are three ocean trenches in the Atlantic Ocean
Where does the sediment on the abyssal plain come from?
It comes from sea mounts and ocean trenches.
Trenches are the deepest parts of the ocean floor which of the earth's four oceans hs the deepest trenches?
The Pacific Ocean has the deepest trenches.
What ocean has many deep valleys or trenches?
Trenches
