Deepest Feature Of The Ocean Floor

Many ocean floor features are a result of the interactions that occur at the edges of these plates.

Deepest feature of the ocean floor. The deepest features of the ocean floor are the trenches that divide the continental plates. It is the deepest oceanic trench on earth. The deepest ocean depth to be sounded is in the challenger deep of the mariana trench. Oceanic trenches typically extend 3 to 4 km 1 9 to 2 5 mi below the level of the surrounding oceanic floor.

The ocean basin floor is everywhere covered by sediments of different types and origins. The deepest ever sighting of an octopus has been made by cameras on the indian ocean floor. Oceanic trenches in the ocean are long but narrow topographic depressions on the sea floor the deepest parts of the ocean floor. The pacific ocean has around 50 000km of convergent plate margins and most of the deepest point located around this place.

As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches. A joint french american crew jacques piccard and don walsh in 1960 and national geographic explorer in residence james cameron in 2012. Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long. Only three people have visited the challenger deep the deepest ocean trench in the world.

The ocean floor is called the abyssal plain. The shifting plates may collide converge move away diverge or slide past transform each other. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. 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 animal was spotted 7 000m down in the java trench almost 2km deeper than the previous reliable. The challenger deep at the bottom of the mariana trench lies deep in the pacific ocean near the island of guam. Geographical activities created deep trenches beneath the ocean that thousands of feet in. When continental plates pull apart they create major.

Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. Features of the ocean include the continental shelf slope and rise.

These oceanographic features are the deepest parts of the ocean floor. Sediment thickness in the oceans averages about 450 metres 1 500 feet.
