What is hidden in the deepest part of Mariana Trench 10994 m? Watermelon video is decrypted for you.

There are countless mountains, grasslands, deserts, lakes, rivers, forests, and vast and unfathomable oceans on the earth, but so far, human exploration of the earth is far from enough, especially in the deep sea, which many people think is a desolate place with high pressure, darkness, silence, cold and bad environment, and it is difficult for life to survive in it.

But in recent years, with the development of science and technology, human detectors have also penetrated into the Mariana Trench with a depth of 10,000 meters. In this deep sea, there have been magical discoveries, which are different from the inherent impression of human beings. What is this? Let's open the watermelon video and search the creator of the watermelon video. Follow the creator's perspective and find out!

Mariana Trench was formed 60 million years ago. It is located in the western Pacific Ocean, east of Mariana Islands. It is the result of collision between the Pacific plate and the Eurasian plate. Because of the high rock density and low position of the Pacific plate, it dived under the Eurasian plate, and after entering the mantle, the plate gradually melted and disappeared, forming a trench at the collision.

Although it is called a trench, the terrain is not an "abyss", but the distance is different and the arc distribution is different, which is quite different from our imagination. Most of its water depth is 8000 meters, and the deepest point is 1 1034 meters, which is the deepest point in the world, enough to drown the Himalayas, the highest peak of the earth at 8844.43 meters. So far, many people in the world have climbed Mount Everest, but no one can go deep into the deepest part of the Mariana Trench.

However, human beings climbed to the top, flew into space, and of course wanted to challenge the deep sea. Mankind has never given up on the exploration of Mariana Trench.

1960, the U.S. Navy's submersible Trieste dived into the trench10916m, and found that there was darkness everywhere and the water pressure was huge, so no living things could survive here at all. In 20 14, scientists explored the mariana trench again and accidentally found a fish at a depth of 8 145 meters. With the deepening of exploration, people have summed up a map of life in Mariana Trench:

Compared with the1-3m underwater area where ordinary humans can move, the100m underwater area is the activity range of giant octopus, whale shark and killer whale, and the 500m underwater area is the diving depth of blue whale, cancer and yellow croaker. Within 1200m underwater, it is the living area of great white sharks and king squid, while at 2000m underwater, there are deep-sea black dragon fish, and further down, there are sperm whales at 2200m and deep sea. ? ? ? Fish is 4500 meters, Mariana lionfish is 8076 meters. ...

Is there life down there? You know, Mount Everest, the highest peak in the world at an altitude of 8843.43 meters, has been extinct.

Of course, the answer is yes. This is the magic of the ocean. At the depth of 0/0600 meters in Mariana Trench/Kloc-0, there is a magical single-celled organism "Giant Amoeba". When you reach 65,438+00,994 meters underwater, the deepest part of the Mariana Trench, the surface is about 65,438+065,438+000 atmospheric pressure. If people are inside, it's like thousands of people stepping on you. Imagine that horrible picture, it will make people shudder, so they will admire the magic of nature's creation and the mystery of people living in it.

The Mariana Trench, with its harsh living environment, should be one of the most uninhabitable places on earth in our impression. However, somehow, the Mariana Trench not only has a thriving biological population, but also forms its own unique ecosystem.

As we all know, the ocean is a dull and silent world below 1000 meters, and there are fewer and fewer fish below1000 meters, but below 4000 meters, it seems to be "cathode yang". We not only found sperm whales in the Mariana Trench at a depth of 4000 meters, but also found new types of hydra jellyfish, purple sea cucumbers, deep-sea anglerfish and sparkling. You know, at this depth, the terror of water pressure can even crush tanks. If people go deep into it, they will be ground into powder, but incredibly, there are still fish here to survive!

The reason is that deep-sea creatures have a * * * similarity, that is, their cell membranes generally contain a lot of unsaturated fat, which helps to maintain the mobility of energy and prevent cell membranes from breaking.

In addition, each deep-sea creature also has its own "life-saving way".

Take the lionfish that lives 8000 meters underwater as an example. Although it is small, only the size of our palms, it has large and wide winglike fins, a small head and small eyes, a tail and a fan-shaped face like an eel. It is different from other fish in that its bones are very thin and its body is soft. The skin of lionfish is not a fish, but a thin film, which makes the physiological tissues in lionfish full of water and can maintain internal and external pressure.

It is worth mentioning that in the Mariana Trench at the depth of 10000 meters, some things that should not exist, such as plastic garbage, indicate that human activities are destroying nature more and more seriously, and it is urgent to study the degradation of plastics to reduce the pollution of marine plastics.
