The trenches are evidence that one of the colliding plates is moving beneath the other.
As the two plates move together, one gets pushed below the other. The place where this sinking/bucking occurs creates a deep trench. The deepest of which is Marianas trench about 7 miles deep.

JordanOceanic trenches are found in association with subduction zones because they are formed when one tectonic plate is forced beneath another, creating a deep trench in the ocean floor. Subduction zones are areas where one plate is being pushed beneath another, leading to the formation of trenches.

What boundary can a trench be found?
Trenches are typically found at the boundaries of tectonic plates, where one plate is being subducted beneath another. The most well-known trenches are oceanic trenches, found underwater near subduction zones where one tectonic plate sinks beneath another.
When oceanic plates come together what land form does this event create?
When oceanic plates come together, they create a subduction zone where one plate is forced beneath the other. This process forms deep ocean trenches and can lead to the formation of volcanic arcs and islands.
Subduction zones are found near what kind of boundaries?
Subduction zones are found near convergent plate boundaries, where two tectonic plates collide and one plate is forced beneath the other, leading to the formation of deep ocean trenches and volcanic arcs.
Where are deep oceanic trenches found?
Deep oceanic trenches are found in the Earth's oceans, primarily at convergent plate boundaries where one tectonic plate is being forced beneath another. Some well-known deep oceanic trenches include the Mariana Trench in the western Pacific Ocean and the Peru-Chile Trench off the coast of South America.
What causes an oceanic trench to form?
They are formed at destructive plate boundaries where one plates subducts under another. The deep sea trench marks the point at which the denser plate ( or faster plate when it is oceanic vs. oceanic) begins to subduct the lighter one. They are very long, narrow and steep-sided depressions in the ocean floor.
