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

Deep ocean trenches are surficial evidence for?
Sinking of oceanic lithosphere into the mantle at a subduction zone.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
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.
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
Deep ocean trenches are surficial evidence for?
Sinking of oceanic lithosphere into the mantle at a subduction zone.
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.
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
