Why don t the confluence of the Yellow Sea and the Bohai Sea merge with the same seawater?

The Bohai Sea and the Yellow Sea are two seas in the northern waters of China, and the dividing line between the two seas is more than 100 kilometers long. On both sides of the dividing line between the Yellow Sea and the Bohai Sea, the sea water is distinct and incompatible with each other. The Bohai Sea in the west is slightly turbid and yellowish; To the east, the Yellow Sea is clear and deep blue.

So why don't the confluence of the Yellow Sea and the Bohai Sea merge with the same seawater?

First of all, the Bohai Sea is shallower than the Yellow Sea, and the Yellow River water is mixed with a large amount of sediment into the Bohai Sea, resulting in the Bohai Sea being more turbid and yellowish in color than the Yellow Sea. In addition, the Bohai Sea is an inland sea, surrounded by the mainland and several islands, which makes the fluidity of the Bohai Sea worse, and the already turbid Bohai Sea is even less likely to become clear.

Secondly, the estuaries of the Yellow River, Liaohe River, Haihe River and other rivers are all in the Bohai Sea, and a large amount of fresh water is continuously injected into the Bohai Sea, resulting in the salinity of the Bohai Sea becoming lower and the density of the sea water being lower than that of the Yellow Sea. Depending on the Atlantic and Pacific Oceans, even if the waters are not turbid, there will be a difference in color at the dividing line between the two.

It is mainly the above two reasons that make the Yellow Sea and the Bohai Sea appear to be incompatible with each other, and it is not a supernatural force.

Also, something interesting. Due to the different density of sea water at the confluence of the Yellow Sea and the Bohai Sea, when the ship passes through this dividing line, the buoyancy changes, and the hull of the ship sinks, resulting in a sense of turbulence. If you have the opportunity, you can experience it.

Due to the high sediment content of the Yellow River, the color is yellow, and the density of the sea water is different when it enters the estuary, and it will flow downward, so it will present the scene of yellow and blue convergence. In addition to the difference in density, these two water bodies are also accompanied by water color differences, forming this more visually impactful water color front.

It's not called cold, but the amount of sand flowing out of the two rivers is different.

First of all, the Bohai Sea is turbid yellow, but the Yellow Sea is different, because the Bohai Sea is an inland sea, so the depth of the trench here is shallow, and the depth of the Yellow Sea trench is deep. Because it is injected into the Yellow River, which contains a lot of soil and gravel, the water of the Bohai Sea will turn yellow.

The Yellow River itself is freshwater, and its salt content is different from that of seawater. As the Yellow River continues to flow into the Bohai Sea, the water in the region is gradually diluted. When the material in the water is different, the density will also be different, and through the difference in density, density convection is formed, so the boundary in the ocean is clear.

The sea is very calm, the winds and tides on the surface of the sea are constantly changing, and when these factors converge, the boundary between the Yellow Sea and the Bohai Sea changes. But the water is still in an unfused state, so strange sights appear in this area.

In fact, on the boundary line of the Yellow and Bohai Seas, the position of the boundary line will also change when the sun shines on the boundary line. At noon, the direct rays of the sun will be strong, but the borders are not very bright due to the presence of a lot of silt on the borders. However, when the sun rises or is ready to set in the morning or afternoon, the tilt of the sun will make the dividing line clear and the difference in color will be large.

The dividing line between the Yellow Sea and the Bohai Sea is a natural phenomenon formed by the movement of trenches on the seabed and the different water colors of the Yellow Sea and the Bohai Sea. The dividing line between the Yellow Sea and the Bohai Sea is the connection between the old iron mountain in Lushun, Liaoning Province and the Hengshan Mountain in Penglaitian, Shandong Province. In 2000, Zhang Jian, a hero who crossed the sea, successfully crossed the Bohai Strait in 50 hours and 22 minutes, and this place has also become a new tourist hotspot.

The Yellow Sea is a marginal sea in the western Pacific Ocean, a semi-enclosed marginal sea typical of the western Pacific Ocean, which is located between China and the Korean Peninsula. It is a semi-enclosed sea that runs approximately north-south.

The name of the Yellow Sea** is due to the fact that the water color of a large area of water is earthy yellow, because the Yellow River has been flowing into the Yellow Sea for more than seven or eight hundred years in history, so that some small amount of sediment carried by the river water has dyed the water near the Yellow Sea from blue to yellow. Internationally, the Chinese name "Yellow Sea" is usually used.

The Bohai Sea is the northernmost offshore area of China. The total length of the coastline is about 3,800 km. It is about 346 kilometers wide from east to west and 550 kilometers long from north to south.

It covers an area of about 80,000 square kilometers and has an average depth of 18 meters. The Bohai Sea is a nearly enclosed inland sea, which is bounded by the Yellow Sea in the east by the line from the Laotieshan Cape of the Liaodong Peninsula through Miaodao to the Penglai Cape at the northern tip of the Shandong Peninsula. The other three sides are surrounded by land, and the north, west and south sides are adjacent to Liaoning, Hebei, Tianjin and Shandong provinces and one city respectively.

According to the topography, the Bohai Sea can be divided into five parts: Liaodong Bay, Bohai Bay, Laizhou Bay, ** shallow sea basin and Bohai Strait.

This is mainly due to the movement of ocean currents and the influence of seawater microorganisms.

Whenever we mention the sea, the first thing that comes to many people's minds is the clear blue water, and this image is the first sense of many people. However, in real life, not every sea is blue, some places will be dark blue or even black, some places will be blue or even bright blue, and the brightness of the sea water at different latitudes will vary.

1. The first reason is the movement of ocean currents.

We can try to observe the color of the sea at different latitudes, and when the latitude of a place is getting higher and higher, the color of the sea in that place will also be darker. Around the equator, the water is generally blue or even blue. However, in the Bohai Sea and the Yellow Sea at higher latitudes, the waters in the relevant areas are generally brown and blue.

If the latitude is further increased, the color of the sea near the Sea of Japan and the Arctic Ocean is generally dark blue. It is precisely because the degree of current movement at different latitudes varies that the movement of ocean currents directly determines the color of the sea water in the relevant sea area. <>

2. The second reason is the impurity of seawater.

We can observe the sea quality of the sea near Bohai Bay, because there is a certain amount of sediment in the sea water in the relevant area, so the color of the sea water is generally brown. When we look at the waters around Southeast Asia, we will find that the local speech movement will further clean up the impurities of the seawater, so the color of the local water will be blue. <>

3. The third reason is the microbial influence of seawater.

In areas with low latitudes, the local seawater is relatively transparent because the microorganisms in the local seawater are relatively active, and the microorganisms themselves will also clean up the impurities in the seawater. In China's Bohai Sea, Yellow Sea and East China Sea, because the microorganisms in these areas cannot clean up the suspended solids in the seawater in time, the visibility of the seawater will be relatively low, and the color of the seawater will naturally become darker. <>

There are three reasons why China's Bohai, Yellow and East China Seas do not have clear blue watersThe first reason is complex hydrological factors, the second is the presence of certain pollution, and the third reason is that the Yangtze River and the Yellow River carry a large amount of sediment into the sea. Although China is still muddy, the open sea is still very clear.

Hydrological factors. The transparency of the ocean is mainly related to the impurities in the seawater. The reason why China does not have very blue and transparent water needs to be analyzed from a geographical point of view.

First of all, one of the most important influencing factors is ocean currents, and the global circulation mainly includes the equatorial flow system, the radiation belt flow system and the western boundary flow system. From the geographical point of view of China, it is mainly located in the western border basin, and China's Bohai Sea, Yellow Sea and East China Sea are all located on this current system, and this region also has a unified name Kuroshio. The Kuroshio Ocean is darker in color and is predominantly blue-black.

The sea water here contains relatively few impurities, and there is plenty of sunshine. When sunlight hits the sea level, the light is scattered. Light is not completely transparent, and is mainly divided into three primary colors: blue, red and yellow.

When sunlight shines into the sea and scatters, when there are fewer impurities, red and yellow light will be absorbed, while blue light is scattered and becomes blue-black, so the overall transparency of the ocean is relatively low. If the ocean is too clear, it proves that the amount of hydrocarbons in the ocean is excessive, resulting in a large number of plankton not being able to survive, and the number of animals and plants in the ocean that feed on plankton is reduced, resulting in a decrease in fish and other animals. This is the truth that if the water is clear, there are no fish.

Sediment of the Yangtze River and the Yellow River. The Yangtze River and the Yellow River in China will carry a large amount of sediment before entering the sea, especially the situation of the Yellow River passing through the Loess Plateau. When a large amount of sediment and water enter the sea, it will definitely have a certain impact on the water color of the offshore ocean.

There is pollution offshore. In addition, it is not excluded that human pollution of the ocean and large-scale aquaculture will lead to the occurrence of red tides and other phenomena. However, with the protection of the oceans in our country, pollution no longer exists.

The reason for this is not pollution, but a combination of complex hydrological factors. The seawater we see every day is mainly the seawater along the coasts of the Bohai Sea, the Yellow Sea, and the East China Sea, and the seawater of the larger oceans is less transparent. But today we are talking about the difference in the transparency of China's seawater and the reasons for the seawater in other regions, so there is no distinction between coastal and oceanic ones, and they are unified into the East China Sea.

It may be due to the climate, so the moisture is not the same, the evaporation is also very fast, and the color is not the same.

China's four seas are the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea, and only the South China Sea is relatively blue. It also has to do with latitude. The color of the sea is also the color of the sky.

The water of the Yellow River and the sea water can be combined!

It's just that under natural conditions, this process of integration,It is a process in which two water mass molecules penetrate into each other through the irregular thermal movement of the molecules

If the difference between the two water masses is greater (especially in terms of density), the slower the fusion will be.

In fact, similar phenomena occur not only in liquids, but also in gases.

Weather forecastDo you often hear cold air, cold waves? The strong cold air blows to the place where the warm air stays, and the two do not mix, but form an interface, along which the warm air is forced to rise, so the cold front is formed--- which is the phenomenon caused by the gas "not having time to blend".

Of course, when we encounter liquids that are difficult to blend, we can do work on them (such as stirring) to speed up the fusion process. There is a lack of this under natural conditions, and the Yellow River is still replenishing its water, so the river-sea boundary can be observed for a long time during the flood season. But once the dry season begins, the Yellow River loses its replenishment, and you can soon observe the fusion of the Yellow River and the sea.

The main reason why the Yellow River and the sea cannot be integrated is that the density difference between the two is particularly large, when the two liquid liquids blend with each other, they will form a very obvious sea peak, which also makes it appear a very peculiar landscape, producing obvious interfaces, which makes people marvel at it.

The main reason why the Yellow River and the sea do not blend is because there is a lot of sediment in the Yellow River, because the density of the water on both sides is different.

The sediment and other substances contained in the water of the Yellow River are extremely rich, but the Yellow River itself is also freshwater, which is different from the salt contained in the seawater, so when the water of the Yellow River is continuously injected into the Bohai Sea area, the seawater in this area is gradually diluted, and the salt and other substances contained in the seawater are also diluted. And when the material in the water is different, there will be a difference in density, and through the difference in density, density convection will also be formed, so there will be a clear dividing line in the ocean.

The sea is very calm, and the winds and tides on the sea surface are constantly changing, and when these factors converge, the boundary between the Yellow Sea and the Bohai Sea will also change. However, the sea is still in a state of non-fusion, so this strange sight appeared in the area.

The source of the Yellow River

The "yellow" of the Yellow River is actually sediment. Ancient books contain: "The Yellow River fights water, and the mud dwells in its seventh".

According to the analysis of modern measured data, the average sediment transport capacity of the main stream of the Yellow River is 1.6 billion tons, and the sediment content is 35 kilograms per cubic meter, which is the highest sediment content among the world's rivers. Ninety percent of the Yellow River comes from the Loess Plateau. The soil here is loose, easy to erode and disperse.

Every time a heavy rainstorm washes away, a large amount of water and soil is lost, and it rushes into the Yellow River.

The area above the Duoshi Gorge in Maduo County, Qinghai Province is the source area of the river, with an area of 10,000 square kilometers, which is a part of the Qinghai Plateau, which belongs to the wide valley belt of the lake basin and is above 4,200 meters above sea level. The basin is surrounded by majestic mountains, with Yaradadze Mountain in the west, Anima Qing Mountain (also known as Jishi Mountain) Kuanzhou in the east, Burhan Buda Mountain Range in the north, Bayan Kala Mountain and the Yangtze River basin in the south. At the western end of the lake basin, there is the ancient Zonglie, which is the birthplace of the Yellow River.
