The pressure in the deep sea is very high, what is the reason?

Preface: The reason why the pressure in the deep sea is very high is also because there is no oxygen in the depths of the seabed, and the density of the sea water is very high, so there will be high pressure. More than 70% of the earth's land is occupied by the ocean, and the ocean also contains a huge amount of water resources.

The ocean also forms an important part of the vapor cycle in the atmosphere. If humans want to work on the bottom of the sea, they need to wear professional diving suits, and the depth they can dive to is very low. If you want to go to the depths of the sea, you need to use a submarine.

to be able to ensure their own safety.

Everyone should know the working principle of the submarine, because the submarine can adjust its own weight by storing water, the submarine will discharge the volume of water in the work, at this time the buoyancy becomes greater than the gravity, there will be an upward situation, if the gravity is greater than the buoyancy, the submarine will fall. So the ascent and descent of the submarine is caused according to the influence of water pressure. The greater the distance the submarine dives, the stronger the pressure in the seawater, because there is no way for humans to survive in the depths of the sea, so if you want to work in the deep sea, you must use a submarine.

Because of the atmospheric pressure in the ocean.

Very different from the atmospheric pressure on the ground, the material of the submarine is very strong and pressure-resistant, and has a certain ductility.

So this is also the decisive factor of diving. Many metals are flattened in the depths of the ocean, which is why deep-sea fish.

It is also safe and sound because the body structure of deep-sea fish is very special and can adapt to this extreme environment.

At present, human beings have found that the deepest fish living in the seabed are only more than 8,100 meters away from the sea level, but at more than 8,100 meters below, there may be deeper creatures, but this distance is already the limit of human diving.

This is related to the depth, the pressure at the deep sea is mainly ** seawater, the density of seawater and the depth of seawater are multiplied, that is, the pressure of seawater, the pressure of seawater is very large, so the pressure is also very large.

Because the sea water is affected by gravity at the deep sea, the sea water above creates strong water pressure, and the salt content of the deep sea is also very high, so the pressure is very high.

Because the water pressure in the deep sea is very high, the oxygen content is very small, so the pressure in the deep sea is very high, and with the current technology of human beings, it is impossible to explore the bottom of the sea.

Because the deep sea is very deep, and the deeper it is, the more water accumulates, so there is a lot of pressure.

It's because of the water in the deep sea, and because the salinity in the deep sea is very high, which has an effect, so it can lead to a lot of pressure.

In the sea, the greater the depth, the greater the pressure for the following reasons:

1.The density of water is greater than that of air, and below sea level, as the depth increases, the density and pressure of the water also increases.

2.When the pressure somewhere in the water increases, so does its temperature. Therefore, in the depths of the seabed, the temperature of the water is very high, resulting in a lot of pressure as well.

3.The gross gravity of the earth also exerts pressure on the water, so the pressure at the depths of the ocean floor is also affected by the gravity of the earth.

In summary, in the sea, the greater the depth, the greater the pressure due to the increasing density and pressure of the water and the influence of the earth's gravity.

The earth's center trembles and repentance, attracting all objects on the earth to the center of the earth to generate gravity! At the same time, there is a downward pressure, and the deeper you are in the sea, the more pressure the lower water source will be under the upper sea!

If the former seepage calls the ocean about 67 kilometers deep. The pressure on the seabed rises to about 7 tons per square centimeter. The density of water rises to York per cubic centimeter.

Fish species live in the sea for a long time, resulting in a very unique body structure, which has long been slowly integrated into the living environment of the deep sea; It's as if a fish species have lived in the deep sea for a long time, and it is a big reason that they will die on land.

Internationally, the relevant international economic organizations have fixed the name of the water area beyond 1,000 meters deep as the deep sea, to give a very brand image a little example, because in the case of this depth 1, the gas pressure of 1000 meters depth 1 is equivalent to about 500 pounds of big fat man moving back and forth on your body, just thinking about it makes people feel unbearable. Some people will ask, at a depth of 1000 meters or more1, why are the fish safe there, when the working pressure is so great that even metal materials can be easily squeezed and flattened?

The metal material bent because the metal material took on more work pressure than his instinctive reaction took, and the metal material was only made to better integrate into an object on land, and it was logical that he could not give full play to his lethality in the deep sea. However, a unique creature like a fish has lived in the deep sea for a long time, and it has long been integrated into the high-pressure living environment, and if it suddenly changes its working environment, it is likely that it will not be able to stand it.

In order to better integrate into the extreme living environment here, the population living in the deep sea area will also slowly evolve and change the shape of the current situation to achieve the goal of development, which is reflected in the biological progression, and it is likely that it will become such a shape to integrate into the natural environment long ago. In fact, fish in the sustainable development of the link, has long been in order to survive and survive, if you usually pay careful attention to the words will find that the cartilage of the fish species in the deep sea is very wonderful, the muscles of the fish will slowly become more and more soft, the fish tissue will become more and more abnormally thin, so that the shape of the fish will be filled with water in order to achieve an extreme balance with the external work pressure. In fact, the fact that Yuzhi will not be under the pressure of working in the deep sea is just as big as people will have high reactions, but people who have long lived in the plateau area are the same at all times.

Because the body of these creatures is very soft, and there is a lot of gelatinous matter in the body of these creatures, the surface of these creatures is very well breathable, and seawater can directly penetrate into the organisms, so they can resist the huge pressure.

This is because the structure of deep-sea organisms and the external pressure are in equilibrium, and the epidermis and internal organs of these organisms can withstand tremendous pressure, so they can resist tremendous pressure.

Creatures in the deep sea have always evolved to adapt to their environment, and creatures in the deep sea will choose to breathe with their gills and lungs, and then they will be able to resist the great pressure.

This is due to the fact that the body structure of creatures in the deep sea is more resistant to stress, which is why this happens.

How much pressure is there on the seabed?

The deepest trench in the world is the Mariana Trench, which is about 11,000 meters deep. Based on the relationship that for every 10 meters of water depth, the pressure increases by 1 atmosphere, and it is not difficult to calculate that the pressure there is about 1100 atmospheres.

The American submersible Trieste once dived to the bottom of the Mariana Trench, and the submersible's shell successfully withstood the test of 1,100 atmospheres, that is, more than 1,000 kilograms of pressure on an area the size of a human fingernail. After careful calculations, Robert Taut believed: there, the submersible withstood a pressure of 150,000 tons, which is equivalent to the weight of two and a half aircraft carriers.

In fact, the steel submersible, with a diameter of 218 centimeters and a wall thickness of 87 millimeters, was compressed by 2 millimeters under the pressure of seawater, causing the paint to peel off the submersible. It is not difficult to imagine that life on land is still possible to survive at such a sea floor. However, on January 23, 1960, when Picard and his son descended to the bottom of the Mariana Trench aboard the Trieste submersible, they spotted a flounder-like fish swimming.

This fish is about 30 centimeters long and 15 centimeters wide, with a flattened body and slightly protruding eyes.

According to the formula p=f s, the deepest part of the seabed is more than 11,000 meters, and 10 is equivalent to 1 atmosphere, so it is 1,100 atmospheres, plus 1 earth atmosphere is 1,101, which is the 8th power of Pa,

One atmosphere is about 10 meters of water, and the deepest part of the ocean floor is 11,000 meters of the Mariana Trench, which is about 1,100 atmospheres.

It can be converted in this way, 1 megapascal per 100 meters, depending on the depth of the sea.

The reason why deep-sea fish are able to withstand so much stress is because they don't need to be stressed at all. Just like an opened can, even if it sinks to the bottom of the sea, the pressure inside and outside the can is the same, so there is no such thing as a pressure difference.

Humans depend on a gas-filled lung to survive, and on land, the internal pressure in our body is only one atmosphere, which makes us feel comfortable. However, when we dive to the bottom of the pool, our ears and nose may feel sore or uncomfortable. That is, because they contain air inside, and this discomfort comes from the fact that the air sacs in the body are flattened by the pressure of water.

Therefore, when Jiaolong is in the depths of the ocean, the most important thing is the pressure level, and every 10 meters of water depth in the ocean will increase by 1 atmosphere. At a depth of 100 meters, the pressure is about 10 atmospheres, which is 10 times greater than the pressure at sea level.

Deep-sea jellyfish. The pressure in the depths of the ocean is enormous, and if it is deep enough, the confined metal like a submarine will also be flattened. But some creatures can still survive here, because the creatures that live in the deep sea no longer have to live in gas-filled spaces like lungs or fish bladders, and their bodies are filled with water, which is difficult to compress. This, combined with their special cellular and tissue structures, allows these organisms to withstand the pressures of the deep sea.

In addition, their soft body structure allows them to remain undamaged under the pressure of high-pressure seawater. Fish in the deep sea do not have as much fat as fish in the shallow sea, and some fish do not even have fat. The low amount of gas in the body can also reduce the pressure difference, so that the body and the sea water can maintain pressure balance as much as possible.

Deep-sea fishSo, deep-sea fish have evolved a unique ecological structure in order to survive. And this problem, in fact, is to use the human way of thinking to apply to the fish, although the fish in the deep sea have made various changes in order to survive, but life will find its way out.

Because the pressure in the deep sea is very high, fish slowly evolve fish scales, and fish scales can protect fish from water pressure.

Because fish are not subjected to any pressure of injury at all, and they have adapted to life in the deep sea and have a unique body structure.

Because fish don't need to be stressed. The gills allow fish to flow seawater through their bodies without having to bear the pressure of seawater.

Fish have lived in the sea for a long time, formed a special body structure, and have gradually adapted to the living environment of the ocean; It's like a fish that lives in the ocean for a long time and dies on land.

In the international community, relevant international organizations have fixed the name of the sea area more than 1,000 meters deep as the deep sea, to give a more vivid example, because at this depth, the pressure at a depth of 1,000 meters is equivalent to about 500 pounds of fat people moving back and forth on your body, just thinking about it makes people feel unbearable. Some people will ask, at a depth of 1,000 meters or more, when the pressure is so great that even metal can be easily flattened, why are the fish safe there?

Metal bent because it was under more pressure than he instinctively could bear, and metal was only made to fit something on land, and naturally he could not exert its power in the ocean. But a special creature like a fish, which has lived in the ocean for a long time, has adapted to that high-pressure living environment, and if it suddenly changes the production environment, it may not be able to stand it.

In order to adapt to the harsh living environment here, species living in deep-sea areas will gradually evolve and change their forms to achieve the purpose of survival, which is vividly reflected in the evolution of biology, and may have already formed such a form to adapt to such an environment. In fact, in the process of continuous evolution, fish have been to survive and survive, if you usually pay close attention, you will find that the bones of fish in the deep sea are very peculiar, fish muscles will gradually become very soft, and the ** tissues of fish will become abnormally thin, so that the fish in the form of the body will be filled with water to achieve a perfect equilibrium with external pressure. In fact, the fact that fish are not subject to the pressure of the deep sea is just like people who have altitude sickness, but it is the same thing that people who have lived on the plateau are the same at all times.
