What is the difference between a continental flow and a deep ocean?

There are two different geographical areas in the world oceans - a continental shelf and a deep ocean, also known as a huge level. The continental shelf is a large area of ​​shallow (less than 150 m, 500 ft) of the sea, which extends about 50 miles (82 km) from world continents. During the ice age, more water is locked in world ice caps, the sea level decreases and the continental shelves are exposed. The famous areas of the continental shelf include the Siberian shelves that people once crossed to America, the Sunda Police in the South China Sea, the Police of the North Sea and the Gulf, all of which are supposed to have been inhabited by people. The depth increases, lowering the lower one at an angle between 1 ° and 10 °. At a depth of about 0.9 km (3,000 ft), sunlight no longer reaches the depths of the ocean and the pressure is about90 times greater than on the surface, equivalent pressure on the surface of Venus. Only some animals can survive in depths greater than this because ecosystems must depend either on detritusU, which falls from above or chemotrophic bacteria that are fed by hydrothermal openings or for cold leakage. In a completely dark environment, many animals are able to generate their own light - the ability known as bioluminescence.

Most of the world's sea life is found on a continental shelf where it is well lit. This marine life includes representatives from 37 of all 38 animal phyla: only one phylum, Velvet Worms, lacks the sea version. Corals and mushrooms create a colorful bottom and thousands of fish species avoid predators between Kelp forests. In addition to the continental shelf, there is also life, but most of which are up to 150 m (500 ft) surface.

Dark Abyssalian plains covering most of the ocean bottom are largely deserts, lacking life. Some species that live here include non -atures, giant isopods and exotic primitive fish such as Blobfish.
