Humans dived 10,000 meters underwater in the Mariana Trench, what did they find? Here comes the truth

Introduction: With the continuous progress of science and technology in my country, there have been many satellites launched by humans in space now. Through these satellites, we can better observe every place on the earth, but from the satellite we can only see the general situation of the earth's surface, more for the land, but there is no way to use the interior of the ocean. Satellite to detect. Now we usually rely on submarines to explore the ocean.

Humans dived 10,000 meters underwater in the Mariana Trench, what did they find? Here comes the truth

70% of the earth is ocean. At present, we divide the sea area on earth into four oceans. These oceans are vast and deep inside. Submarines can dive into the underwater world to observe the ocean, but people's current science and technology are limited.

The submarines made now have not been able to fully dive into the deepest depths of the ocean, so the ocean is still mysterious to us, and there are still many secrets waiting for human beings to explore.

The deepest ocean in the world is the Mariana Trench. This place is located in the Pacific Ocean. In this sea area, the water is relatively clear. However, as the depth goes down, the light in the sea will be significantly weakened. French explorer Geonnery At this depth, it set a world record for the deepest human free diving - 113 meters.

It is very difficult to artificially dive into the seabed to observe the specific situation, because the pressure in the sea is different from that on land. The pressure that humans can withstand in the sea is limited. Once it exceeds the range that the body can bear, problems will arise. hallucinations.

If you dive to 332 meters in this sea area, the pressure generated in the sea water can directly crush a steel plate. If the depth reaches about 1000 meters, there is almost no light that can penetrate in this place, so it is pitch black around this place, and it is impossible to see things clearly.

Of course, there are still creatures below this depth. Most of the creatures living in this place have no eyes, and some creatures have evolved organs that emit light on their own.

Continue to dive for 3000 meters. After reaching this depth, people will find that almost all creatures in this place have no eyes, and more than 75% of the fish can emit light by themselves. This light can be used for Lighting can also warn predators.

Moreover, the water pressure in this place is relatively strong, and most of the diving materials will break when they arrive here. If humans appear in this place, they will be shattered almost instantly. Of course, under normal circumstances, people can't reach this depth and the corpse will be eaten by other fish.

Continue to dive down to a depth of 7,000 meters. After arriving at this place, there are basically no creatures, because the environment of this place is really unsuitable for survival, and the pressure is too high and there is no suitable food. Therefore, the creatures living here are relatively rare, and they are all rare species.

They do not see light all year round, relying solely on the debris deposited by the upper ocean to maintain the energy cycle of the biosphere. my country's Jiaolong once dived to 7,062 meters, which is the maximum depth of submarine diving at present.

Conclusion: The Mariana Trench is indeed very deep. At present, human exploration of the deep sea has only reached about 7,000 meters, but human exploration of the deep sea will not stop there. At present, there are also related researchers who want to invent a more capable submarine to explore the true face of the Mariana Trench.
