How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Why do passive margins have no trenches?
Trenches are caused by plate movement.
What was the reserve trenches like?
Reserve trenches
When was In the Trenches created?
In the Trenches was created on 2007-01-30.
How are valleys and trenches alike and how do they differ?
Unlike deep sea trenches which are found in areas where one tectonic plate slides beneath another undersea canyons are found along the slopes of most continental margins the submarine canyons for example tend to have steeper side slopes much higher gradients and considerably narrower floors. thats how they different
What happens when continental and continental collide?
Deep ocean trenches form
Where trenches do not exist the steep continental slope merges into a more gradual incline known as the continental?
Rise
How deep trenches are formed?
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
What are valley's under water called?
Continental shelf
What geologic features are associated with each type of convergent boundary?
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
Why are there no trenches on the east coast of the US?
It is a passive continental margin. There is no subduction or convergence.
Where do trenches form?
Treches are formed when an ocean plate subducts under a continental plate.
A list of things on the ocean floor?

What does the collision of a continental plate and an oceanic plate produce?
when two plates collide they form trenches.
Subduction of oceanic crust at a continental margin creates .?
Ocean trenches and Island arcs.
Where do trenches not exist the steep continental slope merges into a more gradual incline known as the continental what?
Where trenches do not exist, the steep continental slope merges into a more gradual incline known as the continental rise. This region is formed by the accumulation of sediments that have been transported down the slope, creating a more gentle transition to the ocean floor. The continental rise typically features a broad, gently sloping area that extends toward the abyssal plain.
What is a continental slide?
A continental slide is the new crust on the earth surface. It happens when two plates below the earth surfaces meets and the boundary became deep trenches.
