Deep underwater 10,000 meters, in the deepest part of the ocean, the Marianas Trench, water pressure is hard to imagine

The water in the Marianas Trench is crystal clear, but the magic is that as long as more than 100 meters below the seafloor, vision will be weakened can not see what the bottom of the sea looks like, vision is extremely limited, and there was a hair over the explorer set a record of - 113 meters. Why say below 100 meters vision is still blurred it, the reason is the role of the human's magnetic field, as long as within a certain depth, humans began to hallucinate, began to lose their way, for divers, down to the bottom of the sea must have contrast things to distinguish the direction.

The pressure of the water is so great that ordinary people can not imagine it, when deep into the seawater 300 meters a little, the pressure of the water is enough to crush a large piece of steel plate.

The further down, the lower the visibility, the darker the field of vision, when reaching 1000 lost, it has completely entered the darkness. At this depth of some sea creatures are no eyes, because they can not see things clearly, so the eyes can not evolve.

Further down to the bottom of the sea about 3000 meters, this degree of depth, not only some microorganisms do not have eyes, even fish have not evolved eyes, they need to rely on touch and senses to carry out a series of operations if they need to hunt, these organs that rely on survival will evolve better than shallow water animals. This depth may not be harmful to creatures that have lived in this environment for a long time, but for foreign species that suddenly enter this field, including humans, is not enough to withstand this pressure, which can kill people.

Further down to the bottom of the sea 7000 meters, this depth is estimated that only high-tech submarines and the like can enter to find out, such as China's Jiaolong, which successfully dived into this depth and brought back some samples for our scientists to study, the depth reached by the Jiaolong is also recorded so far, the deepest place reached by human society. This depth of sunlight can not shine in at all, so this place is unable to photosynthesize, and can only rely on the accumulation of material to maintain the cycle.

If you can continue down to more than 8000 meters, then the water pressure at this depth is anything but touchable high pressure, if humans reach this depth, it is not surprising that the internal organs are crushed. As we all know, the deeper the bottom of the sea, not only to withstand the huge also subject to pressure but also to withstand the extremely cold temperature, the light cold temperature at this level, it is impossible for creatures will survive, which is not only a challenge for humans, for any living creature, no pressure, the temperature is an irresistible problem.

But some creatures live under the sea for years and will gradually adapt to this environment, according to the natural law of survival of the fittest, to survive the creatures can adapt to this environment comfortable species, such as scientists found the lionfish, its evolution is based on the changes in this environment to adjust to enable him to successfully survive in such a harsh environment.

Probing deeper, the high-tech submarine is no longer greeted by simple low temperature and high pressure, but by the rolling heat wave of the Marianas Trench coming from a region close to the earth's core, a heat wave that would also instantly shatter the submarine. Clever scientists use lionfish as a sample to study submarines that can explore deeper in this environment to complete the study of the deeper sea floor.

As we mentioned earlier, the deeper you go, the colder the temperature, someone will ask, so deep seawater, will not freeze?

This is the magic of nature, certainly will not freeze, because nature itself has a balance system, it will adjust itself according to the different depths to achieve a smooth state.
