Deepest Parts Of The Ocean Floor

Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long.

Deepest parts of the ocean floor.

The oceans deepest area is the mariana trench also called the marianas trench which is in the western part of the pacific ocean. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. 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 following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

The trench is 1 554 miles long and 44 miles wide or 120 times larger than the grand canyon. Deepest point in the world s oceans. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. Ocean trenches form some of the deepest locations in earth s oceans.

These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates. It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. An example of an ocean trench is shown in the diagram. 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.

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. An oceanic trench is a long and narrow depression in the ocean floor. These oceanographic features are the deepest parts of the ocean floor. It is the deepest oceanic trench on earth.
