The concentration of salt in the Dead Sea, why is the salt content of the Dead Sea so high?

Ordinary oceans are thousandths.

The Dead Sea is 10 times more than theirs.

The salt content of the sea is only about one-seventh that of the Dead Sea, so why is the salt content of the Dead Sea so high?

This has to do with the geography of the Dead Sea. The Dead Sea is surrounded by mountains and plateaus, and the Dead Sea is sunk into it like water stored at the bottom of a huge cauldron. Moreover, this "cauldron" is still buried below the horizon.

In 1848, the Western geologist Linch came here and measured that the water level of the Dead Sea was 392 meters lower than the sea level of the Mediterranean Sea, which is only 100 kilometers away. It was then learned that the Dead Sea was the lowest depression on Earth. At such a low level, it is impossible for water to drain out of its own accord, so only a few less large rivers, such as the Jordan and Al Ahsa, pour water into the Dead Sea, and no river diverts water from there.

Since the river is flowing into the river and there is no water flowing out of the Dead Sea, will the sea level of the Dead Sea gradually rise?

No, it won't. Because the climate in this area is extremely hot and dry, the evaporation of the lake water is extremely high, and the water flowing into the river can only replenish the amount of water that has evaporated. In fact, in modern times, due to the increase in human activities, the amount of water drawn from rivers such as the Jordan River has increased, and the sea level of the Dead Sea has not only risen, but has fallen.

By the 70s of the 20th century, the sea level of the Dead Sea was about 400 meters below the level of the Mediterranean, and 7 meters lower than in 1848.

The water in the lake is evaporating, and the water becomes water vapor and then emits into the air, and the salts dissolved in the water do not evaporate with the water. In this way, the dissolved salts in the water slowly accumulate in the lake, and year after year, they accumulate more and more, making the salt content of the Dead Sea higher and higher. In addition, the Jordan River and other rivers flow through many limestones, and the powerful solvent of water has a strong dissolution effect on the limestone, and the water flowing into the Dead Sea itself contains more mineral salts than ordinary river water, and the salt content of the Dead Sea is of course even higher.

Not only is it still high, but the salt content of the Dead Sea is still increasing, and recently it has been shown that it has a salt content of up to 27%!

With such a high salt content, it is no longer possible for plants and animals to survive. No wonder there are no fish and shrimp in the Dead Sea, not even aquatic plants. That's how the name "Dead Sea" came about.

Later, the undrowned sea became a tourist attraction, and a large number of tourists flocked there every year to experience the experience of the ancient Roman captives. In this regard, the American writer Mark Twain once described it this way: "How fun it is to swim in the Dead Sea, we will never sink!"

You can also straighten your body, lift your head fully up, lie comfortably on your back on the water, and also allow you to spread your umbrella to block out the hot sun. ”

The Dead Sea is also a well-known resort. It was found that the seawater there contains many other mineral salts in addition to table salt, which gives the seawater a certain healing effect. It is said that someone tried to make an ointment using the sea water of the Dead Sea to treat stubborn psoriasis, and it was unexpectedly effective.

Because it's like a well.

The Dead Sea is the lowest body of water on Earth.

Analysis: Salt can also be divided into mineral salt, sea salt, and table salt.

1. Mineral salt, as the name suggests, is the salt mined from mineral salt, like rock salt in the desert, Sichuan salt in Sichuan, and mineral salt mined from Poland hundreds of meters underground.

2. Sea salt is also rich in minerals, mineral salts and sea salts are mostly used to make bath salts, which can be applied to the skin, * In addition to removing keratin, it can also increase blood circulation.

The most famous example is the salt of the Dead Sea, which is six times more concentrated than the average ocean. Rich in minerals and trace elements, it can be **, beautifying, eliminating soreness and dandruff. Boosting blood circulation and growing hair sounds amazing.

3. As for table salt, it is the most stable salt for acid-alkali plants. In addition, if the concentration of salt is high enough, it can have a bactericidal effect; When making homemade skin care products, adding salt to the egg white to apply to the face also has anti-inflammatory and calming effects. It is very suitable for after-sun care.

The salinity of the lake water is as high as 230-250%.

Although the Dead Sea is called "The Sea", it is actually an inland lake, which is a famous large salt lake with a salinity of 230-250%, which is 6-7 times that of ordinary seawater, and is the largest salt lake in the world.

The Hebrew language called the Dead Sea "Salt Sea", because of the large salt content in the lake, the soil on the shore of the lake is also rich in salt, it is difficult for plants to survive in the lake, the fish of the Jordan River die as soon as they come into contact with the water of the Dead Sea, there are no fish in the water, and the birds that feed on the fish naturally do not fly here, and even the vegetation on the surrounding lake shore is difficult to grow, so people call it the "Dead Sea".

Dear, I am glad to answer for you: Dear, for reference, the climate of the region where the Dead Sea is located is dry and hot, with warm winters and no freezing periods, and high temperatures, with an average of 14 17 degrees Celsius; Summers are hot, with an average temperature of 34 degrees Celsius and highs of 51 degrees CelsiusThe surface of the lake (above 40 m) is 19 37 degrees Celsius; Deep (40 100 m) water temperature 22 degrees Celsius

Dry and rainless, with an average annual rainfall of about 50 mm and annual evaporation of about 140 mm.

Because the Dead Sea has no outlet, the Jordan River flows into the Dead Sea about 500 million cubic meters of water per year, but because it is so dry and hot, most of the water flowing into the lake turns into steam, so the water inflow and evaporation of the Dead Sea are almost equal. Due to the high amount of evaporation of the water in the Dead Sea, the surface of the water can sometimes be seen in bursts of fog when the sun shines on it. The lake water evaporated, but the salt brought by the lake water remained in the Dead Sea, after thousands of years, more and more accumulation, so that the salinity of the lake water is as high as 23 25, more than 20 percent higher than the salt content of ordinary seawater, making the Dead Sea a natural salt reservoir.

The Dead Sea contains enough salt to feed more than 4 billion people for 2,000 years. According to statistics, the Dead Sea contains a variety of minerals: 100 million tons of calcium chloride, 100 million tons of sodium chloride (table salt), 2 billion tons of potassium chloride, in addition to bromine, strontium, magnesium, etc.

Extend; Located on the border of Israel, Palestine and Jordan, the Dead Sea is the lowest lake in the world. The deepest part of the lake is meters, and the deepest part of the lake bed is meters above sea level. It is also the third most salinous water body on earth, after the second most salinous pond in Antarctica, and the first in Ethiopia, Gaet'ale pond。

Located in the Great Rift Valley between Israel, Palestine and Jordan, the Dead Sea is 86 kilometers long from north to south and 5 to 16 kilometers wide from east to west, with the deepest point being meters. The shores of the Dead Sea are the lowest point on earth that has been exposed to land, and are known as the "navel of the world". From afar, the Dead Sea resembles a two-tailed fish.

In the sunlight, the sea looks like an ancient bronze mirror. After the 1967 Arab-Israeli war, Israeli forces occupied the entire West Bank.

Three main reasons:1The unique topographic conditions of the Dead Sea are created by the continuous evaporation of the river water flowing into the Dead Sea, the massive sinking of minerals, and the movement of tectonic plates;

2.Temperatures in the Dead Sea range range from 34°C in summer to 51°C in summer and 14-17°C in winterThe higher the temperature, the greater the evaporation;

3.Second, it is dry and rainless, with an average annual rainfall of only 50 mm and evaporation of about 140 mm. With more sunny days, stronger sunshine and less rain, the replenishment of water is negligible, and the Dead Sea is becoming more and more "thick" – more and more minerals are deposited at the bottom of the lake, and the salinity is increasing.

As a result, over the years, the Dead Sea, the saltest saltwater lake in the world, was formed.
