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.
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.
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.
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
What happens at deep-ocean trenches?
subdution
What happens when continental and continental collide?
Deep ocean trenches form
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.
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.

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
What ocean has the greatest number of deep sea trenches?
The pacific ocean
