Best Answer

Subduction is a result of a collision between two tectonic plates, either oceanic to oceanic collision or oceanic to continental plate collision. The heavier, or more dense plate sinks under the more buoyant less dense plate, and is drawn down into the upper mantle.

Well it is all about plate tectonics and the earth's crust moves periodically over a long time. Sometimes it moves apart and splits to create giant gaps in the earth.

What are deep ocean trenches associated with?

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 are deep-ocean trenches?

Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin

How deep do squid live in the ocean?

They live in deep trenches in the ocean.


What happens to the ocean floor at the deep ocean trenches?

what happens is the ocean floor does not just keep spreading.instead, it sinks beneath deep underwater canyons called deep- ocean trenches


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.

Deep ocean trenches are evidence for?

Deep ocean trenches are typically the evidence of the collision of tectonic plates. This collision is often known as subduction.
