Despite a century of research, the Earth is still full of mysteries and secrets.Even on the continent remained unexplored places, but the first place in the number of mysterious puzzles take, of course, the oceans.Scientists do not even have established the exact age of the Earth's oceans, and that is at the bottom of the deepest depressions, we have a very vague idea.And the deep ocean, everyone else will give us many more amazing discoveries.
the smallest of the four oceans of the Earth is considered the Arctic.This mass of ice water washes over the Arctic, and northern Eurasia, Canada and the United States.Despite the cold, the ocean is rich in fish and krill.That's where the whales swim to fatten during the short summer.Third place in this ranking is the Atlantic - its average depth is 3926 meters."Silver" has got the Indian Ocean, with an average depth of 3963 meters.What is the deepest ocean - not hard to guess: of course, quiet.The median its depth reaches 4281 meters.And here is the Mariana Trench, the deepest place of the Earth, is not in the Pacific and the Atlantic, near the island of Guam, and employs 10,790 meters.Ocean depth is determined by a device that catches the reflected sound waves from the bottom.
On the ocean floor, we know little.Scientists, oceanographers have found that the oceans, including the deepest, up to 3600 m deep covered with mud - soft sediments from the remains of small marine life.Silt at a depth of six-kilometer and turn red below.Oceanographers call them "red clay" as biological deposits are blended in the volcanic ash.
Deepest Ocean Earth is surrounded by all the five continents.Western border of the Pacific Ocean say Australia, Eurasia and located between the Malay Archipelago.Its eastern boundary runs along the shores of the Americas, and in the south of "quiet" water wash icy shores of Antarctica.The boundary between the Pacific and Arctic oceans marked by the Bering Strait and lies between the Seward Peninsula and Chukotka.From the Atlantic Ocean separated the deepest imaginary line connecting Cape Horn and the Antarctic Peninsula.The most conventional is the boundary of the Pacific and Indian oceans.Beginning in the Indian subcontinent, it passes through the islands of Java, Sumatra and New Guinea, and ends on the north coast of Australia.
Pacific lead not only in depth.Out of all the Earth's oceans Pacific occupies the largest area equal to nearly 180 thousand square kilometers.For this considerable area is scattered at least ten thousand islands, and in the depths of the ocean located on the planet's greatest underwater ridge that divides it into two unequal parts.The western part is warmed by warm currents and east "freezes" for Peru.The western part of much larger eastern Pacific Ocean is considered to be so also the warmest on Earth.This vast area covering several nature areas - rich flora and fauna inhabited by many.
Pacific - the deepest in the world, but the ocean is not only on our planet.The deepest ocean in the sun is the planet Europe.This small planet orbits the gas giant Jupiter.By the size of Europe slightly less than the moon.It is the center of the iron core, and the surface covered many kilometers thick ice shell.According to a recent confirmation of the hypothesis, under a layer of ice is an ocean depth of one hundred km, covering the entire planet.Scientists suggest that Evropiansky ocean is water that does not freeze because of strong tides, born of the attraction of Jupiter.They do not exclude the existence of this ocean of biological life.
