Typical slopes range between 4 and 16 although slopes as steep as 45 have been measured in the tonga trench of the equatorial south pacific.
What happens to the ocean floor in deep ocean trenches.
The types of rocks found in these ocean trenches are also asymmetrical.
Deep sea trenches and their approaches are striking features on the ocean floor.
An oceanic trench is a long and narrow depression in the ocean floor.
In general the cross sections of deep sea trenches are v shaped with steeper landward sides.
The deepest ocean trench is called the challenger deep part of the mariana trench in the pacific.
Ocean trenches formed by this continental oceanic boundary are asymmetrical.
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.
Ocean trenches are deep cracks in the ocean floor that can extend down into very long valleys.
On a trench s outer slope the oceanic side the slope is gentle as the plate gradually bends into the trench.
Narrow flat abyssal.
These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates.
