What Happens To The Ocean Floor In Deep Ocean Trenches
These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates.
What happens to the ocean floor in deep ocean trenches. On the inner slope continental side the trench walls are much more steep. Narrow flat abyssal. Oceanic trenches typically extend 3 to 4 km 1 9 to 2 5 mi below the level of the surrounding oceanic floor. The deepest ocean depth to be sounded is in the challenger deep of the mariana trench.
Deep sea trenches and their approaches are striking features on the ocean floor. Ocean trenches are deep cracks in the ocean floor that can extend down into very long valleys. Ocean trenches formed by this continental oceanic boundary are asymmetrical. The deepest ocean trench is called the challenger deep part of the mariana trench in the pacific.
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. 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.
