Diagram Ocean Floor Trench

Ocean trenches formed by this continental oceanic boundary are asymmetrical.

Diagram ocean floor trench.

These oceanographic features are the deepest parts of the ocean floor. These plates slowly move toward each other at distances that range from a few millimeters per year to more than 10 centimeters. At the bottom of the mariana trench. 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.

The types of rocks found in these ocean trenches are also asymmetrical. It is the deepest oceanic trench on earth. It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. After scaling the mid ocean ridge and traversing hundreds to thousands of miles of abyssal plains you might encounter an ocean trench.

The deepest ocean depth to be sounded is in the challenger deep of the mariana trench. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. On a trench s outer slope the oceanic side the slope is gentle as the plate gradually bends into the trench. 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.

Mariana trench the mariana trench or marianas trench located in the western pacific ocean approximately 200 kilometres 124 mi east of the mariana islands is the bbc news ocean trench take a dive 11 000m down icy cold pitch black and with crushing pressures the deepest part of the ocean is one of the most hostile places on the planet as a wave of new. These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates. The maximum known depth is 10 984 metres 36 037 ft 25 metres 82 ft 6 825 miles at the southern end of a. Finally you would ascend tens of thousands of feet back up the continental slope and across the continental shelf.

On the inner slope continental side the trench walls are much more steep. An oceanic trench is a long and narrow depression in the ocean floor. Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long.
