With so much pressure in the depths of the ocean, is there no soft soil underneath?

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.

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.

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 in the deep sea is indeed high, but the soil on the bottom of the sea 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 that the water molecules of the deep sea can easily soak into the soil, so that the pressure inside and outside the soil is always the sameTherefore, 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 supernovae**, which contain a large number of heavy metal elements, such as uranium, thorium, gold, silver, lead, etc.

The vast majority of these materials flow into the ocean, where they are gradually deposited on the seafloor and stored in the deep-sea mud due to their high gravityAfter 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 yearsIf 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.

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 drill in.

No, the soil at the bottom of the sea is very loose, because the composition of the deep ocean 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.

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 it 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 compacted.

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.

No, although the atmospheric pressure of 10,000 meters on the seabed is very sufficient, the pressure is mixed with the water, and when the soil and water meet together, it is mud, and it cannot become very compact.

It will not be pressed very tightly, although the pressure will be very high, but there is water on the bottom of the sea, and the soil will be wet by the water and become soft.

No, because seawater will seep into the soil, and the pressure of each part is balanced, and it will not be pressed very strongly.

That's exactly how it looks, because the more pressure there is, the tighter the land becomes.

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 it 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.

There is no soft mud on the bottom of the sea, and if there is soft mud, it will be washed away long ago, and the bottom of the sea is generally rocks or gravel.

Because there is a lot of water in the mud, the pressure is also very high, so there is a soft mud on the seabed.

I think there is, but it is very different from our common silt, which is generally very easy to deform, and then the whole is fluffy and very permeable.

This is because the mud contains a large amount of seawater, and the density of the mud is very high.
