Whales can dive 2,000 meters with no problem, so why are steel submarines crushed?

Whales can dive two thousand meters without being crushed, but our steel submarines cannot withstand the pressure of the deep sea. The main reason is that the whale has adapted to life in the ocean. Its huge body, powerful muscle tissue and special respiratory system help it freely dive into the depths of the sea and float to the sea surface to ventilate. . Whales can thus dive up to two thousand meters deep and move freely without being crushed.

The submarines we make from steel are hollow structures and require people to operate them inside. We need to keep humans safe in submarines, so we need to make sure the interior and interior of submarines are protected. the outside air pressure is constant. MBut as our submarine descends, the pressure will increase by one atmosphere for every ten meters of descent, and our current materials do not allow our submarine to withstand such great pressure on the seabed. Therefore, our submarines cannot move freely in the deep sea like whales.

Additionally, whales can use their lungs to adjust the pressure in their bodies so that their internal pressures are consistent with those outside their bodies. But there is no device to adjust the pressure in our submarine. We can only adjust the weight of the submarine by absorbing and releasing water to achieve sinking and floating effects. Therefore, we make full use of the strength of steel to resist sea pressure. This method is certainly not up to the whale's ability to adapt.

Although the shallow depth of a whale is much deeper than that of our submarine, its diving range is also limited and it cannot dive infinitely, because his body also has a limit tolerance. And generally, the larger the whale, the stronger its diving ability, because the more pressure it can withstand.

Although our submarines cannot dive deep enough to explore the mysterious underwater world, we have special underwater submersibles that do not require humans to do them function. So we solve the problem that humans cannot withstand the huge pressure. on the seabed, such a submersible can even dive up to 10,000 meters deep under the sea for exploration.

Whales cannot dive up to 10,000 meters below theWed.

Whales, as absolute lords of the ocean world, are intimidating with their enormous size and incredible attack power. Whales cannot dive to 10,000 meters, but can only dive to a depth of 3,000 meters at most. So how do they, along with whales and other deep-sea fish, survive in the deep sea? At the international level, relevant international organizations have always referred to sea areas with a depth of more than a thousand meters as the deep sea, to give a more striking example, because at this depth, the pressure at a depth of 1,000 meters is equal to the pressure of. a large man weighing about 500 pounds. The movement of your body back and forth is unbearable just thinking about it. Some may say that at a depth of 1,000 meters or more, the pressure is so great that even metal can easily becrushed, so why was the fish safe? Metal bends because it has withstood pressure that exceeds its natural capacity to resist. Metal is only made to adapt to a certain territory. Naturally, he cannot exert his power in the ocean. But a relatively special creature like fish has been living in the ocean for a long time. She adapted to the high-pressure living environment. If the production environment changes suddenly, she may not be able to support it. Species living in deep sea areas, in order to adapt to the harsh living environment here, will gradually evolve and change shape to achieve the goal of survival. This is fully reflected in the evolution of organisms, and may have already formed like this form. adapt to such an environment. In fact, in the process of continuous evolution, fish are already surviving to survive. If you pay attention, you will noticeYou will notice that the skeletons of whales and other deep-sea fish are very strange, as are the muscles of fish. Will gradually become very... Soft, the skin tissue of the fish will become abnormally thin, so that the body of the fish will be filled with water to achieve perfect balance with the external pressure. In fact, the fact that fish are not affected by the pressure of the deep sea is just like the fact that people suffer from altitude sickness, but it is the same reason for people who have always lived on the board.
