Deepest Parts Of Ocean Floor

The purple sea floor at the center of the view is the puerto rico trench the deepest part of the atlantic ocean and the caribbean sea.

Deepest parts of ocean floor.

The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. Which feature of the ocean floor includes its deepest parts. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. An oceanic trench is a long and narrow depression in the ocean floor.

It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. These plates slowly move toward each other at distances that range from a few millimeters per year to more than 10 centimeters. The ocean floor in particular is home to unique marine organisms as well as enormous geological features like volcanoes canyons and ridgelines. Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long.

These oceanographic features are the deepest parts of the ocean floor. The lesser antilles are on the lower left side of the view and florida is on the upper right. 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. The challenger deep in the mariana trench is the deepest known point in earth s oceans.

Life on the deep ocean floor was assumed to rely solely on falling organic matter and therefore ultimately the sun for its energy source until the discovery of thriving colonies of shrimps and other organisms around hydrothermal vents in the late 1970s. These trenches are considered the deepest part of the ocean floor occurring at the boundary between convergent plates and lithospheric plates. Which oceans border africa. 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.

Research and commercial vessels travel the surface of the ocean regularly but the deepest parts of the ocean remain largely unseen by humans. It has been suggested that more is known about the moon than the deepest parts of the ocean. Check all that apply. Measuring the greatest ocean depth.
