Different Parts Of The Ocean Floor

Deep ocean drilling and radiometric dating in the late 1960s gave an accurate stratigraphy and precise date of the ocean floor.

Different parts of the ocean floor.

In the late 1950s the bathyscaphe deep boat trieste was the first manned vehicle to venture to the deepest parts of the ocean a region of the. Close to shore coral forests are. Learn vocabulary terms and more with flashcards games and other study tools. These areas are mostly found in deep water trenches and canyons.

The deepest point in the ocean is located in the mariana trench off the coast of japan at 35 797 feet 10 911 meters. The ocean has 5 different and distinct layers that each have their own unique characteristics. This layer extends from 6 000 meters 19 686 feet to the bottom of the deepest parts of the ocean. 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.

In still other parts of the ocean you ll find mussels and clams with pearls inside them. 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. From studying the oxygen isotopes of the shells of microfossils in these cores scientists were able to begin studying the earth s past climates in a study known as paleoclimatology. In other parts of the ocean floor you ll find king crabs and flounders.

Of course some scientific research requires actually traveling to the bottom of the ocean to collect samples or directly observe the ocean floor but this is more expensive and can be dangerous. The layers range from the surface layer where most ocean activities occur to the deep dark depths of the water that have yet to be fully explored. This video examines the different types of features in the ocean primarily on the ocean floor. The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone.

Start studying parts of the ocean floor. The trenches around the edges of the eastern pacific ocean are shallower than are those of the western pacific. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
