Where do the 100 million tons of sediment that flows into the sea every year go?

It should have flowed into the seabed, the seabed is very vast, and boundless, and the bottom is also very deep, and this bit of sediment should still not be filled.

No one has ever heard of the sea filled with sediment, such as our Yellow River, you see himHow many have flowed into him every year. , flowing from the Yellow River to various places. It is one of the very large sediment transport reservoirs in China, and every time it passes through the Loess Plateau, it will bring a large amount of sediment to the plain area of the middle and lower reaches of the Yellow River, and the amount of sediment flowing into the sea will be doubled.

The reason why we can't fill the oceans is that we know that the earth is currently 4.5 billion years old, and these rivers have been flowing endlessly from the past to the present.

In the depths of the sea, there are many mountains and ravinesAt the same time, these rugged terrain of the seabed is continuous, and it is connected to all the oceans of the world, so if we can sail underwater along these high mountains, we can even go to the depths of other oceans. And since there are a certain number of cracks in the bottom of the sea, the main reason why these sediments have not completely blocked it is that these canyons are always in an expanding process.

These ravines will drown the sediment, but this is only an aspect of understandingIn fact, although the river carries a lot of sediment, not all the sediment can eventually flow into the sea, and the amount of sediment brought by the river is generally related to the flow speed of the river, if the river enters some gentle areas, the flow rate of the river will be directly slowed down, and the sediment will also be deposited on the road, and at the same time, a new land river will be formed directly in the place where the river passes, and the course will also be changed.

The sea is very big, and our human power has not yet explored it, and the deepest part of the seabed still needs to be excavated by us humans, so we must study our earth itself.

Generally they all sink to the bottom of the sea, because the capacity of the ocean is enormous.

I think some of them sink to the bottom of the sea, and because the sea absorbs them, they disappear.

It must have been absorbed and used by the sea, so it disappeared.

I guess they all sank into the sea, because the weight of the sediment is also very heavy.

I think most of them have sunk to the bottom of the ocean, because the sea is big.

It flows from one part of the earth to another part of the earth, or is it on the earth, and it sinks.

It is estimated that it sank to the bottom of the sea for 20,000 miles, or was eaten by fish.

Big face encyclopedia, three minutes of popular science, where did the sediment that flowed into the sea go, they disappeared out of thin air? It turned out that the earth was separated by a large crack.

All outflow rivers end up in the sea, regardless of the quality of their water. When entering the ocean, rivers carry a certain amount of sediment, so why does it take so long? Didn't the sediment in the sea cause the sea level to rise?

Is it not enough or is it something else?

This must have slowly sunk to the bottom of the sea, slowly accumulating.

With the current level of science, it is not possible to confirm what the truth is, and human beings still need to explore it slowly.

I think some of them are multiplied on the bottom of the sea, and some of them have been salvaged.

As we all know, the rivers on the earth are constantly flowing all the time, and a large amount of sediment flows into the sea with the rivers every dayBut with tens of billions of tonnes of sediment flowing into the ocean every year, why hasn't it caused sea level to rise? This is because there are also marine landforms in the ocean, which are undulating and there are many expanding trenches, which is why the sea level cannot rise even though there is a lot of sediment flowing into the ocean every day.

The sea we see is flat and endless, so we often have the illusion that the bottom of the sea must be flat, but this is not the case, the bottom of the sea has a special seabed landform, and there are many mountains and ravines like the land. These undulating landscapes "swallow up" the sediment as it flows in, and although there is a lot of sediment, it is very small compared to these ravines, so it is difficult to raise the sea level.

In addition, the earth is constantly moving, and those submarine gullies will continue to deepen and widen with the movement and migration of the earth's crust, which is often referred to as the "growth boundary". For example, the Mariana Trench in the Pacific Ocean, the deepest trench in the world, is the growth boundary between two plates, and it becomes bigger and deeper over time, and it is very difficult to fill it.

In fact, some scientists predict that Japan may slip like the Mariana Trench in many years, which has also caused a certain amount of panic in Japan. But in fact, it is also very likely, because judging by the current trend, the Mariana Trench has really been expanding, and maybe one day disaster will befall humanity. Therefore, a large amount of sediment flows into the ocean, but the reason why the sea level does not rise in the poem is that the ocean is constantly increasing and deepening.

Because the sediment is denser than water, it sinks into the trenches on the ocean floor after flowing into the ocean, so it does not rise.

Because the sea is big, deep and inclusive, tens of billions of tonnes of sediment flow into the ocean every year without causing sea level rise.

Tens of billions of tonnes of sediment flow into the ocean every year, and this sediment does not cause sea level rise because sediment can be converted into new substances in the ocean, so it does not cause sea level rise.

The area of seawater on the earth is super large, and it can be said that the earth is a water ball, so the amount of sediment in the Yellow River settles too little in the sea, and it is impossible for the water level of the sea to rise significantly.

Although the Yellow River carries a large amount of sediment into the sea every year, the sea is so vast that the volume of sediment carried by the Yellow River alone is not enough to match the vastness of the sea, and even if it sinks to the bottom of the sea, it is difficult to make the sea water visible to the naked eye**.

Because the sea is very large and deep, such a little sediment is completely impossible, so the sea water will not **, and these sediments will be carried by the sea water to other sea areas.

Everyone knows that the Yellow River is our mother river, and the Yellow River is present"Several"Glyph. The total length is about 5,464 kilometers, and the basin area is about 752443 square kilometers. It is the fifth longest river in the world and the second longest river in China.

It has carried the civilization of our country for 5,000 years, because of the continuous deterioration of the environment in recent years, resulting in the riverbed increasing year by year, and even the world-famous hanging river has appeared. Since 2000, the Yellow River, the world's largest river with the largest sediment discharge and sediment content, has been the world's largest river.

It is understood that the Yellow River produces 1.7 billion tons of sediment every year, of which 1.2 billion tons flow into the sea, and the remaining 500 million tons remain in the lower reaches of the Yellow River for many years, forming an impact plain, on which many farmers and uncles plant trees. So if so much sediment is flowing into the sea in vain, why can't they be dug up and filled in, built roads, houses, etc., and used them?

The dredger can only load dozens of tons at a time, and the speed of the Yellow River to produce sediment far exceeds it, and the use of dredging boats to catch sediment is not as simple as we imagined, and the Yellow River has more mud than sand, after the dredging or sand dredging boats have to transport the sand to other places, and the river sand of the Yellow River can generally only be transported to nearby cities and counties. If the transportation distance is too long, it will increase the transportation cost, whether it is manpower or material resources, it is generally unaffordable. All the transportation and salvage costs may be much higher than the value of the sediment, and the Yellow River has become clearer in recent years, which makes people feel a little uneasy, because the natural laws of the Yellow River, which has been maintained for tens of thousands of years, have suddenly changed, which is not a good sign.

So try to keep the laws of nature as much as possible.

Yellow River

The Yellow River produces 600 million tons of sediment every year, of which 1.2 billion tons flow into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain, which is conducive to planting.
