How deep is the deepest ocean, and can humans explore it?

The deepest ocean reaches 11,034 meters, and humans are currently unable to reach the deepest depths.

Judging from the satellite image, the earth we live on is a blue water ball.

Blue is the presence of the ocean. The oceans occupy 71% of the Earth's area. The vast ocean is also a place where humans want to study.

According to research, the ocean is the origin of life. Humans can be seen swimming in the sea, but they can only move up and down 200 meters, and the pressure is unbearable. Human beings have a special curiosity about the deep sea.

I wondered, how do deep-sea creatures live in the deep sea? A discovery was made recently. How deep is the deepest ocean in the world?

Go 8 kilometers to the bottom of the sea and spot strange fish. <>

The highest peak in the world is Mount Everest.

There are rice. The deepest trench in the ocean is called the Mariana Trench.

The deepest depth of the trench reaches 11,034 meters, which is about twice that of Mount Everest.

Will there be life in the Mariana Trench? Imagine knowing how much pressure there is, enough to crush people into small shrimps.

The same. Humans will not dive, and the technology of diving into the sea is not yet mature. So far, the deepest man can reach is 7,000 meters. Reaching 11034 meters, the submarine will be flattened by water pressure. <>

7000 meters is the maximum that can withstand marine life.

Survive the deepest? According to the findings of the study. Sea level.

Below 1,000 meters, there are small marine creatures with many species. further down, 1,000 to 2,000 meters on the seabed, a zone of large marine life; The seabed is 3000-4000 meters, the water pressure is very large, and the living marine life is medium in size.

Further down, 8,000 meters under the sea. In the opinion, marine life are unbearable environment, nothing exists. But scientists have found that strange species of fish have recently been spotted at a depth of 8,000 meters under the seabed.

It may be due to pressure or other reasons, it looks very strange, but it can survive in the ocean at 8,000 meters below the seabed. At about 10,000 meters under the sea, there should be no life.

The deepest part of the ocean can reach 11,034 meters, a depth that cannot be reached by current human technology. Below 10,000 meters of the seabed, the pressure is very high, and the instruments and equipment are now flattened, and there are no large marine life in this place.

At present, the deepest sea area is about 11,000 meters by acoustic wave measurement, and the existing technology can not be detected at this depth, but China has been developing a deep-sea strategy, and the invention of deep-sea probes such as Jiaolong shows that we will be able to go to the deepest part of the sea to detect in the near future.

The deepest ocean is tens of thousands of meters, and it is difficult to explore it according to current human technology. Because the deeper the ocean floor, the stronger the water pressure.

Acoustic surveying, that is, the emission of a sound signal to the seabed and the measurement of the time of receipt of the signal to determine the depth of the seabed. There is no doubt that the Mariana Trench is currently the deepest.

The Mariana Trench is currently the deepest trench because the Pacific Plate continues to push towards the Eurasian Plate and insert into the lower part of the Eurasian Plate, so the position of the Mariana Trench is pulled apart, and the depth data may continue to be refreshed as the accuracy of geophysical equipment improves. After a few years, the depth of the trench is likely to be the deepest, after the Pacific plate stops moving towards the Eurasian plate.

At present, there is no way to stop the movement at the same time, and it is impossible to judge its deepest data, of course, there must be equipment that can be measured, with the advancement of technology, as scientists continue to work hard, an approximate time and depth of data may be given, and we need to continue to pay attention.

First of all, it is relatively easier for humans to explore space than the ocean (pressure). At present, 98% of human exploration of the sea has not been explored, and there are still many unsolved mysteries about the ocean? Why so many trenches are formed in the earth's oceans is a rare geological landform of cosmic rocky planets.

To date, only the deepest trench, the Mariana Trench, the southeastern side of the Maria Islands in the western Pacific Ocean, has been detected, but there are more than a dozen of them in this ocean area.

The deepest ocean trench on the earth even reaches more than 80,000 meters, which is an unimaginable depth for humans on the earth (in ancient times, Andromeda was a highly civilized intelligent species, and a nuclear catalyst was used to penetrate the ground, and missiles were used to penetrate the depth).

The deepest ocean trench on the earth even reaches more than 80,000 meters, which is an unimaginable depth for humans on the earth (in ancient times, Andromeda was a highly civilized intelligent species, and a nuclear catalyst was used to penetrate the ground, and missiles were used to penetrate the depth).

Many deep seas are inaccessible, and the 10,000-meter-deep trenches in the Atlantic Ocean are even more unknown. In addition, many unknown marine creatures still exist, and the current research on the ocean is best described in one sentence. Therefore, the ocean, which accounts for the largest area of the earth, is even more unknown and a mystery to human beings.

The places where humans have been to the ocean can be said to be just the skin of the ocean.

We should correct our attitude.

At a depth of 7 kilometers, in fact, the current human technology can reach this depth, which is already a very good effect.

More than 10,000 meters. Because the deepest sea area that humans have detected by modern advanced instruments is the Mariana Trench, which is more than 10,000 meters deep.

Until 2020, the deepest sea area explored by humans was 7,000 meters, which was completed by China's Jiaolong, which is a very deep depth.

The ocean floor is 5,000 kilometers deep. Can we humans survey the deepest part of the ocean floor? Humans still cannot reach the deepest part of the ocean floor, because they have very strong pressure, and light has no analogues.

He is very difficult compared to space exploration. According to the data, at a depth of 11,000 meters under the sea, the pressure per square centimeter can reach 1,100 tons, which is equivalent to 3 tanks on a finger. In addition, if you go into the water with people, you must ensure the normal pressure and temperature level in the cabin, which is very difficult for modern technology, and safety cannot be guaranteed In addition, there are many mysterious creatures on the seabed, there are unknown dangers, and the bottom of the sea is very scary for 10,000 meters.

<> as far as the depths of the ocean are concerned, we humans are known to be at the bottom of the Pacific Ocean in the northeastern part of the Philippines, near the Mariana Islands, known as the "Mariana Trench". Located in the subduction zone of the plates, the geological movement is active, where the water pressure is high, the total darkness is low, the temperature is low, the oxygen content is high, in addition, the lack of food is one of the worst conditions on the planet. As far as the sea is concerned, there are always many mysterious legends, such as the lost highly civilized country "Atlantis" or the mysterious Bermuda Triangle, behind which many secrets are hidden that have not yet been revealed.

All of humanity has gone to space, landed on the moon, and the next plan is for Mars, but for the ocean, the dream of a spacewalk – at the bottom of the ocean – is impossible. Because it's harder to explore the ocean than it is to explore space.

"Low visibility, low temperatures, and lack of food resources are among the harshest conditions on Earth, and on January 23, 1960, Belgian researchers used their submersible for the first time in the abyss of 10,000 meters to bury a big article in the history of human adventure civilization, and then Japan also discovered 100,000 meters of seabed, where she found many rare and strange creatures, and what else to fear, because it is related to the future of mankind. The climate of the Pacific Ocean is a well-being suitable for the formation of planetary winds, especially in the South Pacific, because it is widespread and uniform.

The average depth of the world's oceans is about 3,347 meters.

The deepest part of the world's oceans is the Mariana Trench in the Pacific Ocean, with a maximum depth of 11,034 meters, which is near the Philippines and was formed by the subduction of the Pacific plate under the Eurasian plate.

In the case of human hands, there have been people who have created a depth of more than 400 meters, with the help of ropes and heavy objects to sink quickly, and with the help of air bags to quickly float, but there is no oxygen, anti-pressure equipment, etc., basically do not use diving equipment. Wearing a wetsuit and using oxygen, the safe depth of diving is about 400 meters.

If you want to dive to deeper depths, you have to use special oxygen, a mixture of oxygen and noble gases, which can dive to greater depths, but the danger is further increased, mainly because of the problem of blood dissolving other gases.

Classification of ocean depths:

The depth of the ocean is divided into five water layers: the upper ocean layer (above 200 meters), the middle ocean layer (200 meters 1 km), the deep ocean layer (1 km 4 km), the ocean abyssal layer (4 km 6 km), and the ocean ultra-abyssal layer (below 6 km).

According to the intensity of sunlight, from the surface of the ocean to the depth of 200 meters of water, called the upper layer of the ocean, where the sunlight penetrates the seawater, the water is relatively bright, and the sea water is blue and blue; The water layer from 200 meters to 1,000 meters deep is called the middle ocean, where the sunlight cannot pass through all the seawater, the light is very weak, and the sea water is black and blue.

The water layer from 1,000 meters to 4,000 meters is called the semi-deep sea layer, where there is no sunlight at all, it is pitch black, and it is a dark world; Below 4,000 meters is the abyssal layer, which is even darker, but most of the fish in the semi-abyssal and abyssal layers have light-emitting organs to help them forage and move in the dark.

The "Challenger Deep" of the Mariana Trench is the deepest point of the Earth's oceans. It is 10,924 meters below sea level. It is 2,000 meters deeper than the height of Mount Everest.

The only people in history who have explored the abyss are Jacques Picard and Don Worthen. They descended to the bottom of the sea at a depth of 11 kilometers and weighed 8 tons of pressure. They saw fish, shrimp, and other marine life.

1) Mariana Trench in the Pacific Ocean: At 11,033 meters, it is the deepest known trench and the thinnest crust. The trench is located on the western seabed of the North Pacific Ocean, at 11 degrees 21 minutes north latitude and 142 degrees 12 minutes east longitude, that is, near the east of the Mariana Islands.

This trench is a submerged area where the two continental plates converge, and the Pacific plate is submerged under the Philippine plate. The depth of the bottom of the trench below sea level is much higher than that above sea level on Mount Everest.

2) Tonga Trench in the Pacific Ocean: The deepest is 10,882 meters, east of Tong** Island in the south-central Pacific Ocean, from the Samoan Islands in the north to the Kermadec Trench in the south, with a total length of 1,375 kilometers and a width of about 80 kilometers. The average depth is 6,000 meters, with the highest depth reaching 10,882 meters.

3) Pacific Japan Trench: A trench with a maximum depth of 10,682 meters, distributed from north to south on the east side of the Japanese archipelago in the northwest of the Pacific Ocean. It is bordered to the north by the Kuril Trench and to the south by the Trench near the Ogasawara Islands on the east side of the Izu Islands.

It is 890 km long and 100 km wide. The average depth is 6,000 meters. The eastern part of Kashima Beach on Honshu Island is 8,412 meters deep, and the deepest point is on the southeast side of the Izu Islands.

4) Pacific Kuril Trench: The deepest 10,542 meters is a trench near the Kuril Islands in the Pacific Ocean.

5) Philippine Trench in the Pacific Ocean: The deepest 10,497 m trench located east of the Philippine archipelago, stretching from the northeast of Luzon Island to Molu** Island in Halmahera, Indonesia, with a length of about 1,320 km and a width of about 30 km. The Philippine Trench is formed due to the collision of tectonic plates, with the heavier Philippine Plate, made up of basalt, sinking at a rate of 16 centimeters per year below the Eurasian Plate, which is made up of lighter granite.

Where the two tectonic plates meet, is the Philippine Trench.

6) Kermadec Trench in the Pacific Ocean: 10,047 m deep, about 1,500 km long, 60 km wide on average.

7) Puerto Rico Trench in the Atlantic Ocean: The deepest is 9,219 meters, located in the northern part of the Atlantic Ocean, 9,218 kilometers north of the island of Puerto Rico, with a length of about 1,550 kilometers and an average width of 120 kilometers.

8) New Hebrides Trench in the Atlantic Ocean: 9,174 meters deep, located on the edge of the Coral Sea between Vanadhoo (New Hebrides) and New Caledonia. It is about 1200 kilometers long and has an average width of 70 kilometers.

9) Bougainville Trench in the Pacific Ocean: Deepest: 9,140 m, located in the southwest of the Pacific Ocean, 9,140 km west of Bougainville Island.
