How much is the pressure of 10,000 meters under the sea?Equivalent to 2000 adult elephants on the back

Science Fiction Network September 27 (Qin Yingying) China has a long coastline and many islands, and many rivers and lakes. In ancient times, humans lived with collecting and fishing and hunting, and "lived in water and grass." In order to carry out water activities, we must use and manufacture water crossing tools, and the earliest boat boats began to appear. As early as 10,000 to 4,000 years ago, human beings used ancient axes and ancient chisels to create a canoe with continuous mature woodworking technology. The emergence of a canoe began the history of China's shipbuilding industry.

From ancient times to the present, humans have been drifting from the sea to sneaking into the deep sea, from boat to boat to submarines, and humans tirelessly explore the secrets of the sea. We know that the deepest sea in the world is the Mariana Trench, with a depth of 11034 meters. How much is the pressure of 10,000 meters under the sea, how will it feel?

The static water pressure in 10,000 meters deep will reach 1 ton (1,000 kg/square centimeter). Every ten meters of water depth increases, an atmospheric pressure is added. The pressure there is 100 million Pascal. In converted, each square centimeter must bear a ton of pressure. Tian Xiaochuan, chief expert of the Society of Shipbuilding Engineering Society, said that it is equivalent to a person's back and stepped on 2,000 adult elephants.

The "Struggler" manned submersible in my country successfully dived to the Mariana Trench in 2020, and the depth of the sea reached 10058 meters. In November of the same year, the "Struggler" refreshed the record again and sneaked to the bottom of the 10909 meters.

However, in such a deep place, fish still survive. Scientists have found that deep -sea fish are softer than fish muscle tissue in shallow waters and fibrous tissues are more delicate. Their bones are very thin and can bend at will without worrying about being broken by huge water pressure. Deep sea fish skin tissue is basically a very thin layer of film, which can make the physiological tissue in the fish full of water. Keep the balance of the inner and outer water pressure so that they can not be flattened under huge pressure conditions. These may be the reason why deep -sea fish can survive in the deep sea.
