Where does the fresh water you drink by the sea come from, and is the sea water freshwater?

I grew up by the sea, and we used to drink tap water (groundwater drawn by the village itself), but now the tap water is drawn from the city. Let me tell you something, the seaside (on the beach) can produce fresh water, and it is very sweet, when I was a child, when I played at the beach, I drank water from the pressurized water well on the beach. That's what it is:

Rainwater. This is the main part of seaside fresh water, and when it rains, water droplets in the clouds and water vapor in the atmosphere combine to form rainwater, which collects on the ground to form fresh water. This fresh water is filtered and purified, ready to drink, or used for agricultural production and other activities.

Surface water. At the seaside, there are places where there will be surface water, which is usually fresh water from rain, rivers or other water sources. This freshwater may seep through the soil and aquifer near the coastline, forming surface water.

Surface water is usually clear enough to drink or simply treated.

Groundwater. **Groundwater is sometimes present in the ground near the shoreline. This water is usually formed after groundwater and rainwater infiltrate into the ground. Groundwater is usually clean and can be used as is, as is, or simply treated.

Filtration and purification of seawater. **In seaside areas, desalination technology is sometimes used, which filters and purifies seawater to form fresh water. This fresh water can be used for drinking, washing, and other living and productive activities.

When looking for fresh water by the sea, you need to choose the right way to get it according to the situation. It is important to note that in seaside areas, especially during tropical storm season, attention needs to be paid to drinking water safety and hygiene. When treating and purifying drinking water, it is necessary to use water purifiers, filters, or other reliable purification equipment.

Seawater is not freshwater. Freshwater refers to water that contains only low concentrations of dissolved substances such as salts, chlorides and sulfates, while seawater contains high concentrations of salts and other mineralized substances that form a special condition in the hail nucleus ocean.

Organisms cannot survive in environments with high salinity because they need access to water in all environments on Earth to sustain life activities. In a highly salinity environment, water flows out of cells into the ocean, causing biological cells to shrink and thus prevent growth and reproduction. Many living things, including humans, need fresh water to meet their daily needs.

In contrast, organisms in the ocean have evolved a range of ways to adapt to high-salinity environments. For example, marine fish filter water through their kidneys to maintain its salinity. Most marine mammals drink a few milliliters of seawater in the water, which is then separated from substances such as adrenaline and chickpea protein in the body to avoid absorbing too much salt.

In conclusion, seawater and freshwater are two completely different concepts. The chemical composition of the two is very different, and the biological environment to which they adapt is also different. Seawater is a unique ecosystem, while freshwater is one of the essential substances needed for all life. <>

Is there fresh water in the vast ocean? The answer is yes. For example, in the east of Gulei Peninsula in Zhangpu County, southern Fujian in China, there is a small island rich in seaweed called Caiyu, and there is a strange freshwater area on the sea surface about 500 meters away from the island, called "Yudai Spring", which has become the first place for fishermen and boats in this area to replenish fresh water.

The sea area between Florida and northeastern Cuba in the United States is surrounded by high salt content, but there is a 30-meter-diameter sea area in the middle, and the water is light, and the color, temperature, and waves of the sea water here are different from the surrounding water, and it is called "freshwater well".

Why are there "freshwater wells" in the ocean? After scientific investigation, it was found that there is a fountain on the bottom of these "freshwater wells", which can continuously spew out a powerful stream of fresh water, and when the spurted fresh water occupies a certain position, it forms a freshwater area completely different from the surrounding seawater.

Why is there fresh water at the bottom of the sea? This is because hundreds of thousands of years ago these seafloors were a land mass, and the numerous rivers and lakes on the land created favorable conditions for the formation of underground aquifers, and although they have undergone many changes between land and sea, the water in them has been preserved intact.

In the deep sea, the most precious resource of our human beings has been discovered: fresh water!

I know of a place where there is fresh water within 10 nautical miles of the mouth of the Amazon River. Because the water in the Amazon is so large that it dilutes the sea in those places.

Yes, some sea areas, due to underground springs and undercurrents, in some areas will form water areas with lower salinity than the surrounding seawater, the landlord may ask about this, I remember once I read the relevant content, but there is only a little impression, and there is also a relationship between the different salinity of the sea area and evaporative precipitation.

01 Yes. Fresh water at the bottom of the sea comes from land. Every year, 330,000 cubic kilometers of seawater in the ocean are transpired into rain and snow, and some of it seeps into the ground, encountering impervious rock formations, forming aquifers.

If the aquifer is close to the sea, it is possible that fresh water will flow through the coast into the rock formations on the seabed.

Seawater contains a lot of salt, which makes it bitter and salty, and people can't drink it directly, so ships going to sea always have to bring enough fresh water. So, is there fresh water in the ocean?

In fact, scientists have already discovered fresh water on the ocean floor. Scientists believe that the formation of seabed freshwater areas is mainly due to "submarine fountains" and so on. Because the seabed not far from the shore is connected to the terrestrial aquifer, the fresh water that erupts is recharged by the land.

Since the groundwater outcrop is very low, the head pressure is also high below the sea surface. In addition, in the marine and continental interaction strata buried in the ocean circle, the terrestrial strata are also preserved in the freshwater layer.

Where does the fresh water come from? Scientists have come up with many theories through continuous exploration. There are osmosis theories that the fresh water at the bottom of the ocean comes from land.

Every year, a large amount of seawater is transpired into the ocean, and after it falls on the land of Tachibana, some of it seeps into the ground, and when it encounters impermeable rock formations, it forms an aquifer. If the aquifer is close to the sea, it is possible that fresh water will flow through the coast into the rock formations on the seabed.

The condensation theory holds that fresh water from the ground can only penetrate into the seafloor up to a certain limit, but in fact there is still fresh water below this limit, and it is clear that this freshwater does not come from land, but is formed by the condensation of water vapor in the air liquid.

The magma theory is that there are deflating zones deep in the Earth, where a staggering amount of gas, including large amounts of oxygen and hydrogen, is released to form magma water.

The sedimentation theory holds that the origin of groundwater is linked to the sedimentary process of seafloor sediments. A large amount of sediment carried in seawater is deposited layer by layer on the seabed, and the sediment in the lower layer is squeezed out by gravity, and the squeezed water falls with the sediment and is carried into the depths of the formation to form groundwater.

Seabed fresh water has the advantages of large resource reserves, good water quality and no pollution. The rational development of seabed freshwater resources will contribute to the storage of freshwater resources in offshore islands and coastal cities.

The students all know that the sea water is salty. But did you know that there is also fresh water in the ocean?

The answer is yes. In the east of Gulei Peninsula in Zhangpu County, southern Fujian in China, there is a small island rich in seaweed called Caiyu, and there is a strange freshwater area on the sea surface about 500 meters away from the island, called Yudai Spring, where fishermen and boats in this area replenish fresh water. The sea area between Florida and northeastern Cuba in the United States is surrounded by high salt content, but there is a 30-meter-diameter sea area in the middle, and the water is light, and the color, temperature, and waves of the water here are different from the surrounding water, and people call it a freshwater well.

Why are there "freshwater wells" in the ocean? After scientific investigation, it was found that there is a fountain at the bottom of these freshwater wells, which can continuously spew out a strong stream of fresh water, and when the spurted fresh water occupies a certain position, it forms a freshwater area completely different from the surrounding seawater.

Why is there fresh water at the bottom of the sea? This is because some of the seabed was a land mass hundreds of thousands of years ago, and the numerous rivers and lakes on the land created favorable conditions for the formation of underground aquifers, and although they have undergone many changes between land and sea, the water in them has been preserved intact.

Hainan Island is very suitable for people to live in.

Some people wonder how there can be fresh water on the island because it is surrounded by seawater. Actually, this is a misunderstanding. The fresh water on the island is groundwater, and after being filtered by rock formations, the seawater can also be turned into fresh water, so it is not surprising that there is fresh water on the island.

The fresh water on the islands is generally brought in by the water of the underground river, and the water of the underground river is generally freshwater, so even the island has fresh water that people can drink.

The fresh water on the ocean islands may be small puddles that accumulate when it rains, but most islands have no fresh water.

I've read Robinson Crusoe before. When Robinson drifts to an uninhabited island, he thinks he's going to die, but discovers that the island is home to not only a variety of goats, but also fresh water on which humans depend. 。

In the estuaries of large rivers that flow into the ocean, a freshwater area is often formed due to the excessive amount of water. For example, ships sailing near the mouth of the Congo River on the west coast of Africa, although they are nearly 100 kilometers away from the mainland, can get fresh water in the Atlantic Ocean. What's going on?

It turns out that there is a wide submarine valley beneath the sea. This valley is the part of the Congo River that extends from the trough to the bottom of the Atlantic Ocean. The Congo River is the second largest in the world in terms of flow and basin area, with 39,000 cubic meters of water flowing out every second, and a large amount of fresh water is constantly flowing along the river valley from the mainland, forming a freshwater zone on the ocean surface.

The water that passing ships get from outside the mouth of the Congo River is not seawater, but the water of the Congo River.

A few years ago, a freshwater area was also discovered on the southern side of the island of Zmaiine in the northwestern part of the Caspian Sea. The area of this freshwater area is about 1,000 square meters. Since it is located at the mouth of the Danube, therefore, it is considered by some to be part of the waters of the Danube estuary.

The river flows into the Caspian Sea in a sandy layer, but is cut off by winds and strong currents, making it an isolated freshwater area.

Seabed freshwater can not only provide us with abundant freshwater resources, but also provide clues for the search for seabed mineral deposits, which has great scientific and practical significance. They are often connected to certain mineral fields, such as iron ore and manganese ore. Aluminium and chromium have also been found in the bottom sediment of freshwater sources.

Such discoveries have been made in the Caspian and Red Seas, as well as in the waters of the Indian Ocean. It seems that in order to exploit the mineral deposits of the seabed, it is necessary for scientists to conduct research in this area.
