Deepest Feature Of The Ocean Floor

When continental plates pull apart they create major.

Deepest feature of the ocean floor.

It is the deepest oceanic trench on earth. Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover.

The shifting plates may collide converge move away diverge or slide past transform each other. The ocean floor is called the abyssal plain. Geographical activities created deep trenches beneath the ocean that thousands of feet in. The animal was spotted 7 000m down in the java trench almost 2km deeper than the previous reliable.

Features of the ocean include the continental shelf slope and rise. The deepest ever sighting of an octopus has been made by cameras on the indian ocean floor. 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. Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only the ocean floor.

The ocean basin floor is everywhere covered by sediments of different types and origins. The deepest features of the ocean floor are the trenches that divide the continental plates. The pacific ocean has around 50 000km of convergent plate margins and most of the deepest point located around this place. Many ocean floor features are a result of the interactions that occur at the edges of these plates.

Sediment thickness in the oceans averages about 450 metres 1 500 feet. It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches. The deepest ocean depth to be sounded is in the challenger deep of the mariana trench.

Only three people have visited the challenger deep the deepest ocean trench in the world. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. The maximum known depth is 10 984 metres 36 037 ft 25 metres 82 ft 6 825 miles at the southern end of a. Ocean basin ocean basin deep sea sediments.

Oceanic trenches in the ocean are long but narrow topographic depressions on the sea floor the deepest parts of the ocean floor. The challenger deep at the bottom of the mariana trench lies deep in the pacific ocean near the island of guam.
