Deepest Parts Of The Ocean Floor

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

Deepest parts of the ocean floor.

Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. Cousteau submerged his camera to the sea floor of the romanche trench in the atlantic ocean some 24 500 feet down providing the first glimpse of this previously unseen part of the ocean. 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.

It is the deepest oceanic trench on earth. The oceans deepest area is the mariana trench also called the marianas trench which is in the western part of the pacific ocean. These oceanographic features are the deepest parts of the ocean floor. Ocean trenches form some of the deepest locations in earth s oceans.

An example of an ocean trench is shown in the diagram. These plates slowly move toward each other at distances that range from a few millimeters per year to more than 10 centimeters. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. The maximum known depth is 10 984 metres 36 037 ft 25 metres 82 ft 6 825 miles at the southern end of a. Deepest point in the world s oceans.
