The deepest ocean trench is called the challenger deep part of the mariana trench in the pacific.
What happens to the ocean floor in deep ocean trenches.
Narrow flat abyssal.
Deep sea trenches and their approaches are striking features on the ocean floor.
In general the cross sections of deep sea trenches are v shaped with steeper landward sides.
An oceanic trench is a long and narrow depression in the ocean floor.
The deepest ocean depth to be sounded is in the challenger deep of the mariana trench.
On the inner slope continental side the trench walls are much more steep.
The deepest parts of the ocean are found in trenches at more than 35 000 feet nearly 11 000 meters challenger deep is a part of the mariana trench where the pacific plate is subducting beneath the philippine plate.
Oceanic trenches typically extend 3 to 4 km 1 9 to 2 5 mi below the level of the surrounding oceanic floor.
Ocean trenches formed by this continental oceanic boundary are asymmetrical.
These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates.
On a trench s outer slope the oceanic side the slope is gentle as the plate gradually bends into the trench.
