A lake where no river flows. Which sea does the Don River flow into? Scientific research at risk of life

Baikal is not just a legendary lake, it is also very deep.

The water in it is always clean and cold, and it is indebted to the rivers and rivulets that flow to it from all over the world.

What rivers flow into and out of Baikal

Researchers still cannot accurately calculate how many rivers this lake has that flow into it. The rivers flowing into Baikal have beautiful names.

It is interesting that there are rivers such as the Kotochik River, which flows into Turku, and that into Baikal itself. The Upper Angara tributary often misleads geographers who confuse it with the beautiful Angara.

There are a little more than a thousand small rivers and streams, so let’s better deal with the large rivers.

Many rivers of Baikal have their own history. Selenga is considered the largest. It crosses two states and splits into a delta, flowing into Baikal.

This full-flowing beauty brings almost half of all water to the lake, and it receives it from its four tributaries.

The next most beautiful and abundant water is the Upper Angara; this mountainous and capricious beauty can be very unpredictable even on the plain. Near Lake Baikal it forms a bay - the Angara Cathedral.

The very famous Baikal-Amur Mainline stretches along most of the river. Just like the Selenga, this river has tributaries.

The water of all the rivers flowing into Baikal brings with it some surprises. And Barguzin is no exception. Along with the waters, silt, sand and small pebbles enter Baikal.

The river was named so most likely because of the Barguzin sable, which lives here in large quantities. Barguzin carries its unruly waters through the vast expanses of the Buryat Republic.

It originates on the mountain slopes and is filled mainly with rain. This river has a small lake formed by it - Balan-Tamur.

The stormy waters of the Turki are collected from melting snow and rain, and also have tributaries. Not only tributaries, but also Lake Kotokel fills this river with water.

There are still two rivers left with the beautiful names Sarma and Snezhnaya. These are all the rivers flowing into Baikal.

Now we can talk about what rivers flow from Baikal. There is only one river - the Angara. Proud and rebellious, whose waters rush to meet the beautiful Yenisei, being its largest tributary.

Where it originates, lies the legendary shaman-stone. The river is loved by fishermen, as there is a huge amount of different fish in it. The river has many tributaries.

There are four road bridges across it, but there is no railway bridge. In the warm season, ships sail along it. Angara has many islands.

So we found out what rivers Baikal has.

Rivers are picturesque arteries through which the blood of the earth flows. From the very beginning of human history, people have tried to set up settlements and build houses in the coastal zone. Water gave them life. Here they watered the cattle, bathed and cultivated the land. In Ancient Rus', rivers were called “God’s roads.”

Both in winter and in summer they had their own strategic importance. In the warm season, merchant ships glided along large waterways, and in winter, when the surface of the reservoir was covered with an icy surface, merchants transported their goods on sleighs directly across the ice.

Just as blood is important for the human body, fresh water is necessary for the life of nature. Rivers are the main element of the blue planet Earth. As you know, each of them has its own beginning - a source.

Where do they come from?

Almost all rivers have a different source: somewhere a seething stream begins with a small spring, somewhere with a huge waterfall, some rivers are born as a result of snow caps. Such waters are called mountain streams. They are distinguished by their high speed and low temperature; their current can easily carry away even huge blocks of stone. Such rivers are dangerous and unpredictable.

In fact, each begins with its own drainage basin, which, in turn, is fed by many sources. In the spring, when snow and ice melt, rivers are regularly replenished with new water and become fuller, as a result of which they sometimes even overflow. This can be a big problem for coastal residents. As a result of such spills, farmers may lose their crops, and houses built next to the river will become wet and destroyed.

Rivers and their beds

Blue Highways form a giant network of water on the surface of the earth. There are more than 2 million rivers in Russia, 200 of which are quite large. Even huge ships can sail along them. The more modest ones barely cover their muddy bottom. It is known to form a valley and form wide bends in it. Each channel is unique, it has its own slope, individual width and flow. Each “blue ribbon” has its own beginning, its own character and life activity. The flora and fauna of rivers are often similar due to the presence of fresh water.

Where do rivers flow and where do they end?

In the summer, when the temperature rises and the evaporation of moisture increases significantly, the river sources become shallow, and the water flows themselves narrow somewhat. After the spring melting of the ice, the river returns to its original channel to flow further to its end. Wherever the river flows go! They flow into oceans, lakes, seas, and also into other rivers. It is generally accepted that they flow from a hill, heading down.

If we take into account the water flows of Russia, most of them carry their waters to the Arctic Ocean, and only a few to the Atlantic. In the place where the river flows into the sea, the water is desalinated, thanks to which some species of living beings have been able to adapt to life in fresh water bodies.

Volga is the largest water artery

This is one of the most picturesque and largest rivers not only in the country, but also in Europe. It stretches for almost 4,000 kilometers. So, where does it flow? Having originated in the Tver region, it travels along a winding route, divides into many branches and flows into the Caspian Sea. This amazing river has about 200 tributaries, the largest of which are the Oka and Kama. It is worth mentioning that some rivers flow into closed lakes, where their vigorous activity ends.

Current direction

How can you determine where the river flows in your area? In fact, everything is extremely simple. You don't need to be a geologist to understand where rivers flow. First of all, you need to pick up a map and find the desired water flow on it. If a reservoir is shown on the drawing, then the direction of its bed will be clearly indicated by a blue arrow. It happens that you need to determine this while being in nature without a map. What to do in this case? By looking carefully, you can see in which direction the current is moving.

Where in the Northern and Southern Hemispheres? In both the first and second cases, they flow to their mouths. Curious to know what's the difference between them? Their currents are directed in opposite directions. This is regulated not only by the position of the equator, but also by the terrain. For example, we can say with confidence that the source is invariably located significantly higher than the mouth, therefore the water mass, obeying the physical law of universal gravitation, flows from top to bottom.

Unique water flows

People asked the question of where rivers come from and where they flow even at the dawn of human history. Since then, amazing and unusual natural phenomena have been revealed to their eyes more than once. A striking example of this are rivers that can change. Previously, people explained this by the intervention of the gods and interpreted it in their own way, perceiving such changes as signs from above. With the advent of new technologies, it became obvious that there really are bodies of water where the mouth and source sometimes change places, but modern scientists have found a more logical explanation for this.

It turned out that the main factor provoking the change in flow was underground groundwater. When the water level in them begins to fluctuate, this affects the surface flow. Sometimes it is difficult to understand the world around us: where do rivers flow, why do certain phenomena occur? However, it is worth remembering that there is nothing meaningless in nature, everything is created for a specific purpose and functions properly, supporting the life of every living creature.

Practice shows that despite the fact that we live in an age of technology and general technical progress, the purpose of the earth’s waterways has not changed, although the reservoirs themselves have become the subject of careful study and scientific experiments. In recent decades, scientists have been absorbed in studying the structure and molecules of water. Their research proves that this unique liquid is incomparable to any other, it is truly alive! Where do the rivers flow? The surrounding world and nature have provided comprehensive answers to this and many other questions.

There are very special rivers that do not flow anywhere. There are those that change the direction of the current several times during the day.

Among the snow and ice of the Pamir-Altai, the Zeravshan River originates. Having burst out of the mountains, it spreads through hundreds of canals and thousands of irrigation ditches in the Bukhara and Karakul oases. Like many other rivers in desert areas, it has neither a delta nor a mouth. In other words, Zeravshan does not flow anywhere.

Everyone knows that the water in rivers and lakes is fresh. But there are rivers with salty and sweet water.

A river flows in the north, characterized by very high salinity. That's what they call it - Solyanka. Where did the salt in the river come from? Many millions of years ago, on the site of modern Yakutia there was a huge sea. Then the earth's crust rose and fell, in some places closed lagoons were formed, in which, as a result of increased evaporation, thick layers of salt settled, subsequently covered by limestone. Groundwater seeps through these deposits and, saturated with salt, enters the river.

On Victoria Land in Antarctica, scientists have discovered a lake whose water is 11 times saltier than sea water and can only freeze at a temperature of -50°.

There is a lake called Sladkoe in the Urals, in the Chelyabinsk region. Local residents wash their clothes only in it. Even oil stains can be washed off in water without soap. It has been established that the water in the lake is alkaline. It contains soda and sodium chloride. The presence of these substances gave the water special qualities.

There are “vinegar” rivers and lakes around the globe. The “Vinegar” River flows in Colombia (South America). This is El Rio Vinegre (one of the tributaries of the Cauca River), flowing in the area of ​​​​the active Purace volcano. The water of this river contains 1.1% sulfuric and 0.9% hydrochloric acid, so no fish can live in it.

On the island of Sicily there is Lake of Death. Two sources of high concentration acid come from its bottom. This is the “deadest” lake on our planet.

There are rivers that have one common source, but they flow in different directions and often flow into different basins. This natural phenomenon is called river bifurcation. The Orinoco River, which flows in South America, is divided into two in its upper reaches. One of them retains the former name Orinoco, flows into the Atlantic Ocean, and the other, Casiquiare, flows into the Rio Negro River, a left tributary of the Amazon.

Antarctica has amazing lakes. One of them - Vanda - is covered with a thick layer of ice all year round. At the very bottom, at a depth of 60 meters, a layer of salt water with a temperature of +25° was discovered! The mystery is all the more curious because it is believed that there are no hot springs or other sources of heat in the depths of the Earth.

Usually rivers flow into lakes or seas. But there is a river that flows... from the bay into the interior of the mainland. This is the Tadjoura River on the northeast coast of Africa. It flows from the bay of the same name deep into the mainland and flows into Lake Assal.

There is an amazing river in Europe: it flows for six hours to the sea and six hours back. The direction of its flow changes four times a day. This is the Avar (Aviar) river in Greece. Scientists explain the “whims” of the river by fluctuations in the level of the Aegean Sea as a result of ebbs and flows.

"Ink" Lake! It is located in Algeria, near the village of Sidi Bel Abbes. You can write on paper with the water from this lake. Two small rivers flow into the natural “inkwell”. The waters of one of them are rich in iron salts, and the waters of the other are rich in humic substances. They form a liquid similar to ink.

Where does the Kuban River flow? “Of course, to the Sea of ​​Azov,” you say. True, but it turns out that this was not always the case. Even 200 years ago, this river flowed into the Black Sea. It would still flow there now if in 1819 the Cossacks from Staro-Titarovskaya and Temryukovskaya villages had not decided to desalinate the salty Azov estuaries. The Cossacks dug a canal between Kuban and the Akhtanizovsky estuary. But the wayward river “liked” the new channel more than the previous one, and it rushed along it, washed away and widened the banks, carried away everything it encountered on its way, and carried its waters into the Sea of ​​Azov. And the old channel, laid out for the river by nature itself, is overgrown.

The Diala River, which flows through Iraq, was sentenced to death. She was judged by none other than the great Persian king Cyrus. While crossing the Diala, the king lost his “sacred” white horse, which drowned. Angry, Cyrus ordered the digging of 360 canals to divert water from the river. It ceased to exist for a thousand years. Over time, the desert sands dried up and filled with channels, and the river returned to its previous course.

There are many amazing lakes, but nowhere like Mogilnoye. It is located on the small island of Kildin off the Murmansk coast, somewhat east of the entrance to the Kola Bay. The shores of the bay are rocky and steep, but in the southeastern part they go down and form a beautiful bay. Adjacent to it is a lake, separated from the sea by a high sand and pebble bank. The area of ​​the lake is a little more than one square kilometer, the greatest depth is 17 meters. But, despite these modest sizes, the layers of water in it never mix. Vertically, the lake is clearly divided into five “floors”. At the very bottom, the water is saturated with hydrogen sulfide. Above it is a “floor” of red water from many purple bacteria. Then there is a layer of sea water in which dwarf sea fish, sea anemones and starfish live. Higher up, the water is brackish - jellyfish and crustaceans, as well as freshwater fish, live here. The top layer is fresh - inhabited by freshwater animals. During high tides, sea water seeps into the lake through a wall of sand and pebbles that separates the lake from the sea. Heavier water - sea - and less heavy - fresh - almost do not mix with each other, since salty water enters the lake from the side, through the shaft, and fresh water - from above, from rains and melting snow.

The water of some salt lakes has healing properties. Lake Duzkan in Turkmenistan is located on the left bank of the Amu Darya, on the western outskirts of the Sayat village. The concentration of the brine solution is so high that it forms a thick crust. In the summer, especially on weekends, on Duzkan, or, as the locals call it, Lake Sayak, hundreds of people take salt baths to treat rheumatism.

We see the lake as a wonderful vacation spot where you can swim and fish. But not all lakes are like this. Some are truly terrifying. And not in vain.

Lake Pustoe (Russia)

Lake Pustoe is located in Western Siberia in the Kuznetsk Alatau region. Lake Pustoe is a fresh, clean reservoir of continental origin; there are no chemical anomalies in its waters. Many scientists have repeatedly carried out chemical analyzes of water from Lake Pustoy, but not a single study has found toxic substances in it. The lake water is clean, suitable for consumption, similar to champagne due to the smallest bubbles of absolutely harmless natural gases. Scientists have not been able to draw a conclusion about why there are no fish in the reservoir.

In the vicinity of Lake Pustogo there have never been environmental disasters or extraordinary technical incidents polluting the reservoir. The chemical composition of its water does not differ from the nearest reservoirs of the reserve, which are distinguished by an abundance of fish resources. Moreover, the reservoir feeds several fresh, clean reservoirs in the vicinity; the fact that there is fish in them will add special mystery to what is happening in these dreams. There have been several attempts to introduce unpretentious fish species such as pike, perch and crucian carp into the reservoir. Each of them ended in failure, the fish died, the aquatic plants rotted. And today there is no grass or birds on the banks of the reservoir, there are no fish or fry in the water, the lake guards its mysteries.

Why are there no fish in the lake?

Samples from the Kuznetsk reservoir were studied by chemists from the USA, Great Britain and Germany. However, no one was able to put forward a sensible version explaining the lack of fish in the reservoir. Scientists are not yet able to answer the questions of ordinary people about what is happening to the Kuznetsk reservoir. However, scientists repeat attempts to explain the extraordinary phenomenon of Empty Lake with enviable frequency. There are many people who want to visit the shores of the unusual lake; tourists come here and stay overnight. Some of them dream of touching the mystery of nature and unraveling it.

Lake of Death (Italy)

Our world is amazing and beautiful, its nature can be endlessly admired and enjoyed. But besides this, there are places on our Earth that sometimes lead us to bewilderment. Among such places is the Lake of Death on the island of Sicily. This lake can be considered one of the phenomena and unique natural phenomena. The name itself suggests that this lake is deadly for all living things. Any living organism that gets into this lake will inevitably die.

This lake is the most dangerous on our planet. The lake is absolutely lifeless and there are no living organisms in it. The shores of the lake are deserted and lifeless; nothing grows here. Everything is connected with the fact that any living creature that enters the aquatic environment immediately dies. If a person decides to swim in this lake, he will literally dissolve in the lake in a few minutes.

When information about this place appeared in the scientific world, a scientific expedition was immediately sent there to study this phenomenon. The lake revealed its secrets with great difficulty. Water analyzes showed that the lake’s aquatic environment contains a large amount of concentrated sulfuric acid. Scientists were not immediately able to figure out where the sulfuric acid comes from in the lake. Scientists have put forward several hypotheses about this. The first hypothesis stated that at the bottom of the lake there are rocks that, when washed away by water, become enriched with acid. But further study of the lake showed that at the bottom of the lake there are two sources that release concentrated sulfuric acid into the lake’s water environment. This explains why any organic matter dissolves in the lake.

Dead Lake (Kazakhstan)

There is an anomalous lake in Kazakhstan that attracts the attention of many people. It is located in the Taldykurgan region, the village of Gerasimovka. Its dimensions are not large, only 100x60 meters. This body of water is called Dead. The fact is that there is nothing in the lake, neither algae nor fish. The water there is unusually icy. Low water temperatures remain even when there is intense sunshine outside. People drown there all the time. For some unknown reason, scuba divers begin to choke after three minutes of diving. Locals do not advise anyone to go there, and they themselves avoid this anomalous place.

Blue Lake (Kabardino-Balkaria, Russia)

Blue karst abyss in Kabardino-Balkaria. Not a single river or stream flows into this lake, although it loses up to 70 million liters of water every day, but its volume and depth do not change at all. The blue color of the lake is due to the high content of hydrogen sulfide in the water. There are no fish here at all. What makes this lake creepy is the fact that no one has been able to figure out its depth. The fact is that the bottom consists of an extensive system of caves. Researchers have still not been able to figure out what the lowest point of this karst lake is. It is believed that under the Blue Lake is the largest system of underwater caves in the world.

Almost every geographical name has a history of origin. It has long been no secret why the Red Sea was called Red. We know from school that this body of water is the saltiest (not counting the Dead Sea), not a single river flows into it. This sea is the youngest of its kind; it has no equal in the beauty and diversity of the underwater world.

The sea is famous for its coral reefs, most of which are bright red in color. Since the water is crystal clear, it appears red from a bird's eye view. There is also a version about large accumulations of algae or fish, which give the water a corresponding red tint.

2. The color of the rocks.

Ancient sailors were delighted with the unusual red rocks reflected in the sea water, so they dubbed it Red. Why the hills were this color, either because of the setting sun or because of the rock, history is silent.

3. The color of blood.

According to the Bible, Moses led his people through the parting of the Red Sea. When the last Jew set foot on land, the sea closed in, burying the bodies of his pursuers. In that place, the water turned red from their blood, which is why they began to call the sea area Red.

4. Incorrect interpretation of the ancient name.

The Arabs found the writings of the ancient people - the Himyarites, who lived on the sea coast until the 6th century. Their writing did not display short vowels, so the name of the sea, consisting of three consonant letters “x”, “m”, “r”, was interpreted as “ahmar”, which means “red” in Arabic.

5. Translator error.

According to the Bible, Moses and his people passed through the “sea of ​​reeds,” translated into English as “reed sea.” There is an assumption that an error occurred, one letter was lost, and “reed” turned into “red sea” - “Red”.

6. Geographical location.

According to the ancient Assyrian calendar, the cardinal directions were associated with certain colors. For example, red symbolized the south, black – north, green – east, white – west. So it turned out that the sea located in the south began to be called Red.

7. Color of foreign bodies.

According to one version, these could be numerous petals of red flowers, according to another, ground red pepper. But scientists put forward a third, associated with a large number of marine inhabitants of the corresponding color.

Love stories of the red piece of the ocean

But how they could get into the water is explained by several very real stories.

Story 1. Love is red

Oddly enough, every person associates love with different colors: from white to black with the most unusual shades and inclusions, maybe even striped. According to Feng Shui, this feeling is green. But one man proved that his love is bright red, like pink petals, and huge, like the sea.

This happened a very long time ago, even BC, so the names of the heroes of history, unfortunately, have not reached the present day. At that time there lived a young guy on the sea coast; he could not boast of beauty and strength. But he was gifted with a big, kind heart and a sharp mind.

The guy came from a poor family and worked from morning to evening, tirelessly. It so happened that at one of the holidays, where all the residents of the city gather, he saw a beautiful girl from whom he could not take his eyes off. Subsequently, the young man learned that she was the daughter of one of the most respected people in the city. And the saddest thing was that preparations were underway for the wedding, which was to take place in a few weeks.

The lover tried to throw the girl out of his head and heart, but he could not help himself. Every minute her figure in a red cape appeared in front of him, her blue, almost transparent eyes looked into her very soul. Hair the color of sand, wavy, like dunes at the bottom of the sea, did not allow me to breathe calmly.

Realizing that there was very little chance of winning the girl’s heart, the guy decided to take a desperate step. He began to think about a plan that seemed almost unrealistic to conquer a woman’s heart.

Every morning the girl went out onto the balcony of her house to admire the sunrise, which illuminated the clear water with bright rays. The sight she saw one morning struck the young soul.

The entire surface of the sea that was in sight turned from transparent blue to bright red. To find out what happened, the girl went down to the sea. On the shore I saw a man in a boat who did not take his eyes off her. What happened to the water, why did its color change? It turns out that the entire surface was strewn with scarlet rose petals.

The girl, fascinated by what she saw, without hesitation got into the boat, the bottom of which was covered with pink petals, only white ones, and looked in surprise at the young man. The words that the guy said during the boat trip remained forever in the girl’s heart. She fell in love with him at first sight and realized that she would not be happy without him. So no one saw them again. And the rose petals swayed on the sea waves for a long time, which is why the locals called it Red.

Story 2. Peppered sea

In ancient times, a merchant lived in a city on the shore of a warm reservoir. He made his fortune by trading spices, especially red pepper. A person often left his home, spending time on a ship due to his profession.

The merchant lived half his life, but never started a family. They didn’t like him in the city for his greed and malice. The whole house was filled with gold, jewelry and bags of spices. The merchant did not participate in the life of the city, did not help the poor, and treated the defenseless cruelly.

The people decided to expel him at a general meeting. They were allowed to take all the goods and sail to other shores. Out of greed, the merchant loaded his ship so much that, not having time to disappear beyond the horizon, the ship sank. A few hours later the sea turned scarlet from the scattering of a huge amount of pepper.

This is interesting:

The gates of cities in Ancient China had different colors, depending on which side of the world they faced. Also, the tips of the arrows in a modern compass have corresponding colors: red, black, green and white, respectively indicating the parts of the world: south, north, east and west.

In the first “documents” dating back to the second century BC, the Red Sea could be referred to as the Eritrean Sea (Eritrea is a state on the shores of the Red Sea from the East of Africa), and in the 16th century it was called the Suez Sea.

If you break off a branch of bright coral, after a few minutes without water it will lose its attractiveness and turn dirty white or brown. Therefore, tourists cannot get a trophy in the form of red corals, and only a photo of it can preserve such beauty for display to family and friends.

This sea is recognized as the cleanest. Most likely due to the fact that no rivers flow into it. As a rule, they are the ones who carry sand, silt and other particles that pollute the water.

The water here is the saltiest. Firstly, no rivers enter the sea, that is, there is no influx of fresh water, and secondly, the high temperature of water and air contributes to intense evaporation of water, which further increases the concentration of salts. Today it is 41 g per liter of water, in the Black Sea it is only 8 g.

The Red Sea is gradually increasing in size. It is located in a seismic zone where plates move without stopping. Therefore, the banks diverge, the displacement reaches up to 1 cm per year, which means that over the course of a century the border will expand by 1 m.

History contains many mysteries and unusual events. That is why the White Sea is called that way; a definite answer has not yet been received. Often the origin of geographical names has several versions, which are supplemented by modern interpretations. It is often difficult to discern the line between fiction and reality.
