Asked in Oceans and Seas
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. ...
Asked in Earth Sciences
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. ...

Deep ocean trenches are located in the middle of ocean basins?
Deep ocean trenches can be found near continental shelves. Some are found near volcanic islands, and are formed due to plate tectonics. ...

Deep-oceanic trenches are most abundant around the rim of the?
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone. ...
