One type of deep cut is an oceanic trench. These are formed above subduction zones. Which are created as the result of one of the Earth's tectonic plates gradually being forced beneath another - when two tectonic plates collide, oceanic crust always becomes forced underneath continental crust because oceanic crust is denser and heavier, whereas continental crust is lighter and more buoyant. They are often ringed by parallel volcanic mountain chains. Examples of this situation include the Atacama trench & Andes mountains and the Aleutian trench & Aleutian chain. These boundaries are known as convergent or destructive plate boundaries.
Another type of deep cut is the opposite of the above. This is known as a mid-ocean ridge, and this is where new oceanic crust is created (to eventually be destroyed at a subduction zone). This is a known as a divergent or constructive boundary. New ocean floor is gradually being erupted where the tectonic plate is stretched thin and the hot mantle material is able to well up and melt due to a drop in pressure. This system is not uniform, and often creates huge undersea mountain chains with valleys and peaks, showing as a tennis-ball style scar running throughout the world's oceans on maps.
What else can I help you with?
What are Deep underwater canyons called?
The oceans floor doesn't just keep getting wider instead the ocean floor plunges into deep underwater canyons called deepocean trenches.Where ever deep ocean trenches are there is subduction.
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called what?
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
What best describes seamounts and islands of the deep ocean basins?
piles of basaltic lava flows built up from the ocean floor by multiple, summit and flank eruptions
What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
Deepest point of Molloy Deep in Which Ocean?
The deepest point of Molloy Deep is located in the Indian Ocean. The Indian Ocean is the smallest ocean in the world.
Are Sea mounts deep cuts in the ocean floor true of false?
No they are not.
Are Sea mounts are deep cuts in the ocean floor?
Are trenches caused from tectonic activity.
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

probably..

Deep Trench in the ocean floor. It can sometimes be mistaken for a mid-ocean ridge.
