Deep ocean trenches are associated with subduction zones where an ocean plate descends into the asthenosphere. The Ocean plate is heavier than a Continental plate which causes the Ocean plate to slide beneath the Continental plate. As the Ocean plate descends, a deep ocean trench is formed.
What else can I help you with?
Deep-ocean trenches are associated with?
Around the western edge of the Pacific Ocean
What are deep ocean trenches associated with?
Deep ocean trenches are associated with tectonic plate subduction, where one tectonic plate is forced beneath another into the mantle. This process leads to the formation of deep-sea trenches, which are the deepest parts of the ocean floor. Trenches are often sites of intense seismic activity and can also be locations where volcanic arcs form.
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.
What is the name of the large number of trenches and associated volcanic activity that lie along the margins of the Pacific Ocean?
The ring of fire
What ocean has many deep valleys or trenches?
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.
Where do giant squids live in deep oceans trenches or mid ocean trenches?
Giant squid primarily live in deep ocean trenches.
Compared to ocean crust near deep-sea trenches crust near ocean ridges are?
Compared to ocean crust near deep-sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of active seafloor spreading where magma rises to create new crust, while deep-sea trenches are associated with subduction, where older, denser crust is pulled back into the mantle. As a result, the crust at ocean ridges is also less dense and more buoyant than the crust found near trenches.
What are the valleys under the ocean called?
They are called trenches.
Are divergent plate boundaries associated with folded mountains and deep sea trenches?
No. Sea floor trenches are found at convergent boundaries. divergen boundaries form mid-ocean ridges.
Where are trenches located?
in the ocean!
