The deepest ocean is on Earth and not only

Despite centuries of research, the Earth is still full of mysteries and secrets. Even on the continents there are unexplored places, but the first place in the number of mysterious mysteries is, of course, the oceans. Scientists have not established even the exact age of the Earth’s oceans, and we have a very vague idea of ​​what is at the bottom of the deepest troughs. And the deepest ocean, and all the rest will give us many more amazing discoveries.

The Arctic is considered the smallest of the four oceans of the Earth. This mass of icy water washes the Arctic, as well as the northern parts of Eurasia, Canada and the United States. Despite the cold, this ocean is rich in fish and krill. It is there that whales swim to feed themselves out for a short summer. The third place in this rating is occupied by the Atlantic Ocean - its average depth is equal to 3926 meters. Silver went to the Indian Ocean with 3, 963 meters of average depth. What is the deepest ocean - it is not difficult to guess: of course, Pacific. The average of its depth reaches 4281 meters. But the Mariana Trench, the deepest place on Earth, is not in the Pacific Ocean, but in the Atlantic, near the Guam Islands, and totals 10, 790 meters. The depth of the oceans is determined using an instrument that catches sound waves reflected from the bottom.

We know little about the bottom of the oceans. Scientists-oceanographers have determined that the oceans, including the deepest, up to the 3600-meter depth, are covered with silt - soft sediments from the remains of small marine life. Muddy deposits at a depth of six kilometers and below become red. Oceanographers call them "red clay", since volcanic ash is mixed with biological deposits in them.

The deepest ocean of the Earth is surrounded by all five continents. Australia, Eurasia and the Malay Archipelago located between them mark the western border of the Pacific Ocean. Its eastern border runs along the shores of both Americas, and in the south “quiet” waters wash the icy shores of Antarctica. The border between the Pacific and Arctic oceans is marked by the Bering Strait and lies between the Seward and Chukotka peninsulas. From the Atlantic, the deepest ocean is separated by an imaginary line connecting Cape Horn and the Antarctic Peninsula. The most conditional is the boundary of the Pacific and Indian Oceans. Starting on the Indian subcontinent, it passes through the islands of Java, Sumatra and New Guinea, and ends on the northern coast of Australia.

The Pacific Ocean is leading not only in depth. Of all the terrestrial oceans, the Quiet occupies the largest area, equal to almost 180 thousand square kilometers. Not less than ten thousand islands are scattered over this considerable area, and in the depths of the ocean is located the greatest underwater ridge on the planet, dividing it into two unequal parts. Its western part is warmed by warm currents, and the eastern one is “frozen” by the Peruvian current. The western part is much larger than the east, so the Pacific Ocean is also considered the warmest on Earth. In this huge space, covering several natural areas - the richest flora, and many fauna inhabit.

The Pacific Ocean is the deepest on Earth, but the oceans are not only on our planet. The deepest ocean in the Sun system is on the planet Europe. This small planet revolves around the gas giant Jupiter. In size, Europe is slightly smaller than the moon. Its center is the iron core, and the surface is covered with ice shell of many kilometers thickness. According to a recently confirmed hypothesis, under a layer of ice there is an ocean of a hundred kilometer depth occupying the entire planet. Scientists suggest that the European Ocean consists of water that does not freeze due to the powerful tides generated by the attraction of Jupiter. They do not exclude the existence of biological life in this ocean.
