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 evidence for?
Deep ocean trenches are evidence for plate tectonics, showing where one tectonic plate is subducting beneath another. These trenches form at convergent boundaries when the denser oceanic plate sinks into the mantle. The presence of deep ocean trenches also indicates areas of seismic activity and potentially tsunamis.
Deep ocean trenches are surficial evidence for?
plate tectonics and the process of subduction. They are formed where one tectonic plate is forced beneath another, leading to the creation of the deep trenches in the ocean floor. This process is associated with the movement of Earth's lithospheric plates.
What percentage of the ocean bottom is covered by trenches?
Approximately 2.5% of the ocean bottom is covered by trenches, which are deep depressions in the ocean floor that form where tectonic plates collide and one plate is forced beneath the other. These trenches can be incredibly deep, with the Mariana Trench being the deepest known point in the ocean.
What type of scientist studies deep ocean trenches?
A marine geologist or marine geophysicist studies deep ocean trenches. They investigate the topography, geological processes, and tectonic activity of the ocean floor to better understand these unique and mysterious environments.
Which basin contains many deep sea trenches?
The Pacific Ocean basin contains many deep-sea trenches, such as the Mariana Trench, which is the deepest known point in the ocean. These trenches are formed by the subduction of tectonic plates, creating some of the most extreme environments on Earth.
Deep-ocean trenches are associated with?
Around the western edge of the Pacific Ocean
What are 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
Where do giant squids live in deep oceans trenches or mid ocean trenches?
Giant squid primarily live in deep ocean trenches.
What ocean has many deep valleys or trenches?
Trenches
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.

What happens at deep-ocean trenches?
subdution
How deep is a ocean trench?
Some ocean trenches can be as deep as 10,971 m (35,994 ft).
What is deep-trenches?
a deep-ocean trench is a portion of the earth crust
