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.

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?

Trenches occur at convergent boundaries when one tectonic plate which is more dense, is pushed beneath another tectonic plate that is less dense. This process is called subduction. Usually where divergent boundaries in the earth's crust are. When faults move apart, they create trenches.<-- no divergent boundaries in the ocean create mountain ridges not trenches http://upload.wikimedia.org/wikipedia/en/a/a4/SubZone.jpg


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.

What is likely to be found in subduction zones?

In subduction zones, one tectonic plate is forced beneath another, creating intense pressure and heat. This often leads to the formation of deep oceanic trenches, volcanic activity, earthquakes, and the recycling of oceanic crust back into the Earth's mantle through a process called subduction.

Are the oldest rocks of the oceanic crust found in deep ocean trenches far away from active mid-ocean ridges?

No, the oldest rocks of the oceanic crust are typically found near the continents where they have had more time to form and accrete. Deep ocean trenches are usually associated with subduction zones where tectonic plates are being forced underneath each other, rather than locations where new oceanic crust is forming.

Do convergent boundaries have trenches?

Yes, convergent boundaries can have trenches. Trenches are often found at subduction zones where one tectonic plate is being forced beneath another plate. The descending plate forms a trench as it sinks into the mantle.


Description of oceanic-oceanic subduction?

Occurs when ocean crust sinks under continental crust, it sinks because it's colder and denser,at these sites, deep-ocean trenches also form along with coastal mountains. As the oceanic crust moves, these trenches often causes underwater earthquake, as the crust sinks under a continent, the crust buckles to form a range of mountains, like island arcs, parallel to a deep-ocean trench. Some of the mountains are volcanoes, which form as melted oceaninc crust rises through the top plate. For example: Cascade Mountains in Oregon and Washington.


Why are most oceanic trenches found in the pacific ocean?

The Pacific Ocean is part of the Ring of Fire. The ring of fire is underwater trenches made my moving plates. The plates pushed on each other and eventually moved downward, creating trenches

At What type of boundary would a trench be created?

Trenches such as the Peru-Chile trench are found at destructive (also known as convergent) subductive plate margins where the denser oceanic plate is being subducted beneath the lighter continental plate. Trenches are common at subduction zones.
