Diagram Ocean Floor Trench

The types of rocks found in these ocean trenches are also asymmetrical.

Diagram ocean floor trench.

On a trench s outer slope the oceanic side the slope is gentle as the plate gradually bends into the trench. The mariana trench for example is the deepest place in the ocean at 36 201 feet. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. These oceanographic features are the deepest parts of the ocean floor.

The maximum known depth is 10 984 metres 36 037 ft 25 metres 82 ft 6 825 miles at the southern end of a. Mariana trench also called marianas trench deep sea trench in the floor of the western north pacific ocean the deepest such trench known on earth located mostly east as well as south of the mariana islands it is part of the western pacific system of oceanic trenches coinciding with subduction zones points where two adjacent tectonic plates collide one being forced below the other. It is the deepest oceanic trench on earth. Ocean trenches formed by this continental oceanic boundary are asymmetrical.

Oceanic trenches are a distinctive morphological feature of convergent plate boundaries along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year. After scaling the mid ocean ridge and traversing hundreds to thousands of miles of abyssal plains you might encounter an ocean trench. An oceanic trench is a long and narrow depression in the ocean floor. Finally you would ascend tens of thousands of feet back up the continental slope and across the continental shelf.

Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long. At the bottom of the mariana trench. These plates slowly move toward each other at distances that range from a few millimeters per year to more than 10 centimeters. Oceanic trenches typically extend 3 to 4 km 1 9 to 2 5 mi below the level of the surrounding oceanic floor.

The ocean floor is littered with adorable octopuses and actual garbage alongside the wild natural beauty some evidence of humans. On the inner slope continental side the trench walls are much more steep. These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates.
