The deepest seabed has a thousand atmospheres, so will the soil here be pressed very tightly?

Deep-sea mud is called abyssal sediment, which is mainly composed of biological debris and abiotic sediment, and the soil is mostly soft and fine.

The deepest part of the oceanic ocean on Earth is the Mariana Trench in the western Pacific Ocean, which is 11,034 meters deep and has a water pressure of more than 1,060 atmospheres, which is equivalent to carrying tons of weight per square centimeter.

Some people may wonder if there is such a great pressure on the seabed, so will the mud on the seabed be pressed very tightly?

This understanding is incorrect, the pressure of the deep sea is indeed high, but the soil of the seabed is soft; The material composition of the soil is very complex, ranging from the decomposition of the debris of the dead creatures to volcanic ash, mineral deposits, cosmic dust, and so on.

The molecular level of these substances is not as dense as the atomic structure of steel, so the water molecules of the deep sea can easily soak into the soil, so that the pressure inside and outside the soil is always consistent. Therefore, the soil on the seabed is not pressed by the water pressure, and deep-sea animals can easily burrow into the soil to avoid predators.

The ocean covers 71% of the Earth's area, and thousands of tons of cosmic dust fall into the Earth every year, some of which come from the radiation particles of stars, and some from the remnants of supernovas, which contain a large number of heavy metal elements, such as uranium, thorium, gold, silver, lead, etc.

Most of these materials will flow into the ocean, and due to their high specific gravity, they will gradually be deposited on the seabed and stored in the deep-sea soft mud. After hundreds of millions of years of accumulation, deep-sea soft mud has become a special mineral resource, but it is also very difficult to mine.

Every year, a large amount of material is deposited on the seabed, and the soil at the bottom will be compacted more and more, and sedimentary rocks will be formed after millions of years; If it contains a large number of animal and plant remains, after hundreds of millions of years of evolution, it may also form fossil fuels such as coal and oil.

No, the soil at the bottom of the sea is very loose, because the composition of the deep bottom is too complex, mostly the remains of ancient organisms or sediments, so even if the atmospheric pressure is high, it will not become tighter.

The mud in the deep seabed is mainly composed of biological debris and abiotic sediments, and most of them are extremely soft and fine. Even at a pressure of 1,000 atmospheres, due to the complexity of the soil composition, it is basically not pressed very tightly.

A: The deepest part of the ocean floor has a pressure of 1,000 atmospheres, and the soil here is not pressed very tightly.

Because the pressure inside and outside the soil is the same, they will remain loose, and yes, the sea creatures can easily burrow into it.

If it is in the depths of the ocean, the soil will be pressed very tightly. But the mud at the bottom of the ocean is soft. , the influx of seawater, it can be said that the pressure is not great.

The deepest seabed has a pressure of 1,000 atmospheres, and the soil here will be pressed very tightly, and the soil is actually quite delicate, and there is strong pressure in the deepest part of the ocean, and the consequences are really unknown.

Yes. I don't think the soft soil is necessarily silt, but it can also be some rock powder, and although the pressure in the deep sea is high, there should be a lot of rock powder as well.

The soil in the deep sea is not soft. This is the mystery of the sea, and the creatures that grow in the deep sea soil are also very soft.

As living organisms, we depend on a gas-filled space (lungs) to survive, and on land, the internal pressure in our body is only one atmosphere, which makes us feel comfortable.

When we dive to the bottom of the pool, our ears and nose may feel pain or discomfort. This 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 the water.

Therefore, when considering the depths of the ocean, we tend to be most concerned about its stress levels. For every 10 meters of water depth in the ocean, 1 atmosphere of pressure increases.

The seabed is very stressful but still has silt, which is not much different from the physical properties of silt in shallow water. Scientists' exploration of the Mariana Trench has also confirmed that even the seabed at a depth of 10,994 meters has silt, which is fluffy and easily deformed.

Silt refers to the fine-grained soil deposited in the environment of still water and slow flowing water and contains organic matter, because it is rich in biological fiber fragments, so the silt is generally porous, coupled with the activity of microorganisms in the silt, the nature of the silt is quite fluffy, with strong adsorption, and also has good permeability.

The flow rate of water bodies in the ocean is generally relatively slow, and the water replenished by rivers for the ocean is rich in suspended solids, dust particles, biological tissue debris, etc., and marine organisms are extremely rich, and countless organisms will form a lot of organic debris in life and death, metabolism.

Some of them can be suspended in seawater, so that the organic content of seawater is maintained in a certain proportion, and become food for zooplankton**. The other part eventually settles to the bottom of the sea, where it becomes an important food for life on the seabed**, and various materials from volcanic eruptions settle down, forming silt on the bottom of the sea over time.

In short, the water content of the silt is very high, and a large part of the pressure of the seawater will be poured into the seawater burden in the cracks of the silt, and the seawater pressure will not change significantly. Although there are many fibrous fragments in the silt, due to the small diameter, the pressure of the surrounding seawater is just balanced, and the fragments themselves are not very strong, regardless of whether the seawater can compress the various fragments in the silt, the silt will be more proud and fluffy.

No. Because the soil on the seabed will also have the same pressure and will not necessarily be squeezed into a piece, there is soft soil.

Summary. Since water is about 800 times denser than air, the pressure increases by about 1 atmosphere for every meter of descent in the deep ocean. Thus, at 4,000 meters under the sea, the water pressure will reach about 400 atmospheres, or 400 standard atmospheres (10,000 pounds per square inch).

The density of the water is about 800 times higher than that of air, so in the deep sea, for every meter of dive, the pressure increases by about 1 large pin of old air pressure. As a result, at 4,000 meters under the sea, the water pressure will reach about 400 atmospheres, or 400 standard atmospheres (10,000 pounds per square inch).

At depths of 4,000 meters, living beings face very extreme environmental conditions, including enormous water pressure and extremely low temperatures. These environments pose a great challenge to the survival of living things. As adaptors, deep-sea organisms have developed a variety of unique characteristics.

First, let's take a look at what the water pressure is at 4000 meters under the sea. Since water is about 800 times denser than air, the pressure increases by about 1 atmosphere for every meter of descent in the deep ocean. Thus, at 4,000 meters below the seafloor, the water pressure will reach about 400 times the atmospheric pressure of the punch, or 400 standard atmospheres (10,000 pounds per square inch).

This water pressure is almost equivalent to a large truck on your hands, so humans cannot survive in such a deep-sea environment without special equipment. In terms of biology, the bio-scattered lead-sensitive species at depths of 4000 meters are very unique. For example, deep-sea fish such as giant squid, tube-eye fish, and smoky flaming are typical deep-sea creatures.

They often have peculiar forms, such as huge eyes, transparent bodies, or light-emitting organs, which are used to find food and companions in the dark. In addition, there are some invertebrates such as deep-sea crustaceans, radiolaria, deep-sea sponges, etc. These creatures have adapted to the deep-sea environment in a variety of different ways, such as luminescence, huge teeth, etc.

This is because water is much denser than air, and the number of water molecules per unit area in the deep ocean increases with depth due to its own gravity. According to the principles of physics, when an external force is exerted at a certain point, the pressure on that point is correspondingly greater. It is very dangerous and infeasible for humans to be exposed to such a high-intensity, high-density and high-pressure environment for a long time.

Therefore, when carrying out activities such as deep diving or exploration, it is necessary to take strict protective measures and ensure that the equipment and equipment have strong enough judgment and macro tolerance to cope with the challenges that may arise under extreme conditions.

Divers have seen well-known shrimp, squid, octopus, spear squid, and sperm whales and other large sea mammals in thousands of meters of water; Schools of largemouth angler fish were found at depths of 2,000,300 metres: in the water layer below 8,000 metres, new species of fish were found only 18 centimeters in size. If people hadn't seen so many deep-sea creatures with their own eyes and only listened to their rumors, they would have thought that this was a fantasy.

Because, these seemingly very weak beings have to withstand hundreds of atmospheric pressures first. For example, a small fish that people see at more than 7,000 meters of water is actually subjected to more than 700 atmospheres. That is to say, this small fish is under 700 kilograms of pressure at all times on an area the size of our fingernails.

This pressure can flatten a steel tank. It's amazing how much fish can swim freely. In the abyss at a depth of 10,000 meters, people saw small fish and shrimp of several centimeters.

These small fish and shrimp are subjected to pressure of nearly a ton. Such a great pressure, not to mention a tank, even something harder than a tank, will also be squashed.

But why are deep-sea fish able to withstand such tremendous pressure on the seafloor?

It turns out that the physiology of deep-sea fish has changed a lot in order to adapt to the environment. These changes are reflected in the muscles and bones of deep-sea fish. Due to the tremendous water pressure of the deep-sea environment, the bones of the fish become very thin; And it's easy to bend; The muscle tissue becomes particularly flexible and the fibrous tissue becomes surprisingly fine.

What's even more interesting is that the skin tissue of the fish becomes just a very thin membrane, which fills the physiological tissues of the fish with water and maintains the balance of pressure inside and outside the body. This is why deep-sea fish are not squashed under such enormous pressure conditions.

When a deep-water fish lives in deep water, it needs a high pressure in its body to adapt to the water pressure in deep water, especially the gas pressure in its swim bladder is much higher than the atmospheric pressure to adapt to deep-water life. If you swim to shallow water, the air pressure in the body is higher than the external air pressure, so the swim bladder will expand and the fish will die.

That's why it's not possible to buy live deep-water fish on the market.

In addition, the eyes of deep-sea fish have become very peculiar. Our common goldfish are not only very brightly colored and have particularly large eyes, but also have fun. Compared with goldfish, fish that live in the deep sea have a much richer eye structure than goldfish's eyes.

The eyes of ordinary fish mostly grow on the sides of the head, but the eyes of the back fish that live in the deep sea grow on the back of the head. From the front, the two large eye frames of the back fish look like two light bulbs erected. And from above, the two eyes resemble two large circles, occupying the "fortress" part of the head.

What's even more interesting is that this fisheye can move up and down, left and right, and its eyeball structure is similar to that of a telescope, and it can adjust the focus freely. The peculiar eye structure is almost a common physiological feature of deep-sea fish.

The pressure on the ocean floor is about 1,000 times that of the atmosphere. At 3,000 feet under the sea, a piece of wood can be crushed to half of its original volume. Whereas, the earth is round, and when the pressure is balanced, it acts like a triangle.

If you look at the same flat part of the ocean bed as a sphere, then it is not only under pressure where there is seawater, but also where there is land, and if you look at it as a sphere, then it is being stressed in all aspects, and the force should be similar.

To change the bell's words, if you have studied biology, how can your blood vessels withstand such a large blood pressure? The cell membrane is very thin, so why can it withstand the pressure of vacuoles? If you look at it as a whole, then there is no pressure at all, there is a lot of gas on the surface of the earth, and you also know that there is atmospheric pressure on the surface of our earth, but the ground is still good, it has not collapsed by the air, right?

Then the same is true of the pressure of water on the ocean floor and the pressure of air on the surface of our earth.

If it is in the depths of the ocean, the soil will be pressed very tightly. But the mud at the bottom of the ocean is soft. , the influx of seawater, it can be said that the pressure is not great.

The dirt will not be pressed very tightly.

The soil on the seabed is a combination of physical, chemical, and biological sediments (such as the remains of marine organisms and their decompositions, various mineral precipitations, volcanic material, and even dust from the universe). Although the composition of the soil on the seabed is complex, they all have one thing in common, that is, their structure is loose, and there are many voids between the various materials inside them, but the voids in the soil here will not be compressed.

This is because in the ocean, the material that exists in the internal voids of the seabed soil is not air, but the seawater that penetrates into it, because the medium that transmits pressure in the ocean is actually seawater, and the pressure it transmits in all directions is equal, which means that there is equal pressure inside and outside the soil, so the internal voids of the seabed soil will not be compressed, even if the deepest seabed pressure exceeds 1000 atmospheres, the soil here will not be pressed very tightly.

Organisms that live on the bottom of the sea, for some purpose (such as predation, camouflage, etc.), will often burrow in and out of the soil on the bottom of the sea, and appear to be effortless, which indicates that the soil on the bottom of the sea is actually very loose.
