Parts Of The Ocean Floor

It comprises the continental shelf the continental slope and the continental rise.

Parts of the ocean floor. Ocean floor part of the earth s surface beneath the seas and the oceans. Features rising up from the ocean floor include seamounts volcanic islands and the mid oceanic ridges and rises. The trenches around the edges of the eastern pacific ocean are shallower than are those of the western pacific. At the ocean floor submarine ridges of a few hundred kilometres wide and a few thousands kilometres in length are also found.

A trench is a long deep depression in the ocean s floor. The total length of the submarine ridges is more than 75 000 km. Plate tectonics and the ocean floor bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics. Trenches are the deepest part of the ocean and can often be found near chains of volcanic islands or around continental shelves.

Oceans cover over two thirds of the earth. The depth depends on the trenches and valleys in the area. Continental margin underwater extension of the continent. The ridges are either flat like plateau or steep sided mountains.

The hadalpelagic zone lies between 19 686 feet to 36 100 feet. The mariana trench the world s deepest submarine de pression is more than 11 000m below sea level in some parts about 7 000m below the mean depth of the ocean floor. The ocean floor is called the abyssal plain. Japan s marina trench is the deepest part of the ocean ever to be explored by man and it sits at 35 797 feet.

Its topography is highly variable. Is about 1 86 miles high is 930 miles wide and is over 52 000 miles long is formed by magma coming out of the rift located at its center. They are longer than the longest mountain ranges on the continents. The outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.
