The Black Sea washes over seven countries; many tourists flock to its shores during their holidays to swim and relax to their heart's content. A variety of Black Sea resorts are happy to welcome everyone. But what do we know about this sea? Are there interesting facts that we don't know about? Of course have. Let's get to know them in this article.

A sea with many names

Only this sea has had a huge number of names throughout its history of existence. As soon as they didn’t call him. Its very first name was given by the ancient Greeks - Pont Aksinsky. translated it means “inhospitable sea.” It was along it that the Argonauts, led by Jason, sailed in search of the Golden Fleece. It was very difficult to approach the sea, since its shores were inhabited by hostile tribes who fiercely guarded their territory. In addition, there was little information about Ponte Aksinsky, and navigation in those days was not established. Later, after the development and conquest of the coast, it was renamed Pont Evsinsky, which meant “hospitable sea.”

An interesting fact about the Black Sea is that it had many more names that were given to it by different peoples: Cimmerian, Akhshaena, Temarun, Tauride, Holy, Blue, Surozh, Ocean. And in Ancient Rus', until the sixteenth century, it was called Russian or Scythian.

Why is it Black?

There is no clear answer to this question, but there are two hypotheses that hold true. The first says that the reason for this name is hydrogen sulfide. This substance has the property of covering with a black coating metal objects, falling to a depth of more than 150 meters, for example, an anchor. When the sailors picked him up, they saw that he had turned black. This quality of water gave the name to the sea in the future.

The second hypothesis is that in ancient times parts of the world were designated by color. White color meant south, and black meant north. In Turkish, for example, the Mediterranean Sea is called the White Sea, that is, located in the south.

Dangerous and healing inhabitants of the sea

Do you want to know interesting facts about the Black Sea and its inhabitants? For example, about a shark that can help fight cancer? The katran shark lives in the middle waters of the Black Sea. It is small, less than a meter in length, but very dangerous. There are spikes on her back. But vacationers should not be afraid of them: the marine life is afraid of noise, so it does not swim to the shores.

These dogfish sharks are actively used in pharmacology, since their fat has excellent healing properties, and their liver contains a substance that can cure some forms of cancer.

In addition to the mentioned sharks, the Black Sea is home to about 2,500 different animals, among which there are very dangerous ones, such as the sea dragon. On its dorsal fin there are poisonous prickly spines that can be fatal. Another dangerous inhabitant of the Black Sea is the scorpion fish.

There is an interesting fact about the Black Sea in Russia, which says that on August nights it glows like a neon lamp. This happens because it is at this time that sea candles—algae that are capable of bioluminescence—accumulate near the surface of the water. Thanks to this property, the sea sparkles in the dark.

  1. IN winter period, The Black Sea remains almost 90% unfrozen.
  2. The only large peninsula washed by the Black Sea is the Crimean peninsula.
  3. There are no ebbs and flows in this sea, since the waters Atlantic Ocean only in small quantities fall into it.
  4. The Black Sea currents are very interesting: they resemble two whirlpools, with giant waves that look like glasses. The waves reach 400 kilometers. These whirlpools are named after the oceanologist who first described the currents - “Knipovich's glasses.”
  5. Another interesting fact about the Black Sea is that ancient Taman cities hid at its bottom. This happened due to the fact that the sea is increasing in volume very quickly - 25 centimeters per century.
  6. The mountains around the sea are also growing, but not so quickly - about 15 centimeters per hundred years.
  7. About 7500 years ago, on the site of the Black Sea there was a freshwater lake with its inhabitants. As a result of a cataclysm (flood or earthquake), a fault occurred in the soil, and water entered the lake. sea ​​water, flooding it and killing its inhabitants. Their remains, accumulated on the seabed, emit hydrogen sulfide, which turns all the metal black and prevents sea inhabitants from descending to a depth of below 150 meters. According to some sources, the flooding of this lake could be the same flood from which Noah escaped in his ark.

These are the interesting facts about the Black Sea that exist in our history.

Why are eyebrows needed?

This is a natural “headband” that we inherited from our ancestors. Eyebrows prevent acrid sweat and raindrops from rolling down from your forehead directly into your eyes. There is a possibility that the invention of umbrellas and hats, as well as the ruthless evolution over the coming millennia, will remove eyebrows from the list of organs necessary for survival and procreation. Because of this, women of the fourth millennium will no longer need to track discounts on plucking and styling on beauty salon Instagrams.

How does dirt appear in the navel?

The accumulation of dirt in the navel is - no joke - the most mysterious physical process on the human body. Austrian chemist Georg Steinheiser studied the formation process and composition of “umbilical mud” and published the results of his scientific research in 2010. It turns out that during the day, the hairs around the navel collect fibers from clothing and push them inside, where they mix with dust particles, beads of sweat and microscopic particles of skin, falling into clumps. To combat this scourge, says Steinheiser, you can either shave the hair around problem area, or by getting a piercing: the metal will repel dirt and there will be nothing to pick out in the shower in the evenings.

What does the subway smell like?

Creosote is a special chemical used for lubrication. wooden sleepers and other details of the metro. In the quantities in which it is in the air at stations, it is non-toxic and does not cause any unpleasant effects, except for reactions in allergy sufferers. In the subways of other cities (New York, Tokyo, London and even CIS cities - Minsk and Kyiv) this characteristic smell is not present.

If the mother of Russian cities is Kyiv, then who is the father?

First, we need to figure out why Kyiv is still a “mother”, despite the masculine gender. The pre-revolutionary spelling of Kyiv is “Kiev”. Solid sign at the end in the 19th century it did not sound at all, but denoted the hardness of the previous consonant sound. But in IX it was pronounced as an unstressed “o” (for example, like the first two “o” in the word “milk”). During the reign of Prince Oleg, who called Kyiv “the mother of Russian cities,” the word was read as “Kieva” and belonged to the feminine gender. The pope of Russian cities, according to historians, is Novgorod. It was built before Kyiv, and served as an important trading hub - it was the beginning of the legendary route “From the Varangians to the Greeks.”

Do penguins have knees?

There are two sets. The first is the so-called tarsus, which looks like a backwards-turned knee, which almost all birds have, and a real functional knee that connects the femur and tibia.

The problem is that the penguins' tarsus is too close to the foot, and the knee itself is too close to the body. Therefore, the lower legs of penguins look like a solid, rigid structure.

Where does the excavated soil go after the construction of the metro?

She doesn’t disappear anywhere without a trace. Depending on the quality of the resulting soil, the soil is sent either for processing and disposal in technical enterprises, for example, on construction projects Moscow and the region, or, if it good quality, for landscaping parks and forest areas.

What dreams do blind people see?

People who are blind from birth actually see dreams that do not have visual images. Dreams may include sounds, smells, and touches. different combinations, but they won’t even have color or light elements. People who have lost their sight during their lifetime experience normal dreams. Their brightness decreases year after year: colors disappear and images blur, until eventually they fade to zero.

Why do traffic police officers have striped batons?

The contrasting black and white coloring is equally noticeable both in the city and in the field at any time of the day and in any weather. The traffic police came to the idea of ​​painting the batons black and white 77 years ago. Before this, back at the beginning of the century, until traffic lights appeared and the flow of cars grew to the modern endless traffic jam for the entire city, traffic controllers first made do with completely white and then red and yellow wands, similar to the lightsabers from “ Star Wars" Then the USSR launched a bold but unsuccessful experiment: for several years they made do with white gloves and a special set of gestures. It was after the fiasco of this venture that the traffic controllers were given the famous black and white sticks.

What is the most popular word in Russian?

A special organization of linguists monitoring the state of the Russian language found out in 2014 that the most popular word in Russian - the interjection “damn”, which is used in speech even more often than the pronouns “I” and “you”. This says a lot about the state of modern Russian speech.

Will a gun fire in space?

It will definitely shoot once. A bullet, devoid of air friction, gravity and other obstacles, will fly for a very long time and very far (quite likely millions of kilometers) until it falls into the gravitational zone of a star or extinguishes inertia in another way, but the shooter will have to fight with the recoil from shot, spinning around its axis and coping with nausea and disorientation. The second, third and other shots may well not happen: in order for some parts of the pistol to work as required, they need air gap, compensating for friction of parts. So every shot in space will render the gun unusable a thousand times faster than on Earth.

What causes "butterflies in the stomach"?

Adrenalin. For the brain, falling in love is very little different from other types of stress, such as grief or danger. This is why lovers eat little and sleep poorly. As soon as a person sees a loved one, the brain recognizes this as a stress signal and begins to pump adrenaline through the vessels. Please note: you most likely experienced the same sensations in your stomach before an important exam or before an important interview.

Why don't people sneeze in their sleep?

First, you need to understand how people sneeze: the brain receives information about irritation, transmits a signal to the chest muscles to fill the lungs with air, closes the holes in the throat and gives a signal to exhale. The air ends up exploding through the nasopharynx. You can’t sneeze in a dream because problems occur at the very first stage: the brain receives a signal about irritation, but due to the fact that nervous system works in a suppressed “sleep” mode, and cannot do anything about it except wake up the owner if the irritation is strong enough. And then, you won’t be able to sneeze immediately after getting up: the nervous system has not yet entered working mode.

Why are some dreams so difficult to remember?

During sleep, norepinephrine is not released - a hormone that, among its other duties, is responsible for fixing memories in long-term memory. An interesting detail: norepinephrine is released during fulminant stressful situations: injuries and burns, as well as in cases of serious nervous shock, anxiety and fear. This is why nightmares and disturbing dreams are much more memorable than good dreams.

Why do some drinks taste bad after brushing my teeth?

The toothpaste contains sodium lauryl sulfate. It is added as a foaming agent, which makes brushing your teeth easier and distributes the paste more evenly throughout the mouth. The substance is not considered harmful, but may cause an allergic reaction or irritation. Another thing is that upon contact with the tongue, sodium lauryl sulfate suppresses the receptors responsible for sweetness. In addition, the component temporarily destroys the phospholipid layer, which suppresses the bitterness of food. So it turns out that the taste of food and drinks that a person consumes immediately after thoroughly brushing his teeth changes beyond recognition and not for the better.

Why does ice cream hurt my forehead?

The effect is called “brain freeze” and is observed in a third of people living on earth. Unpleasant pressing sensations in the forehead or behind the ears are caused by the fact that from the cold in the mouth (specifically in the palate), the brain is “scared” that the cold will soon reach it, and begins to urgently pump warm blood to itself. Because of this, blood flow is disrupted for some time, and unpleasant sensations arise in the head. In science, the effect is called sphenopalatative ganglioneuralgia. You can make warning stickers and use them to mark ice cream in stores.

What happens to the pages of deceased people on social networks?

In most cases - nothing. Automatic removal pages after a certain period without activity in many in social networks still no. For example, pages on Facebook, Odnoklassniki and VKontakte remain forever. However, Twitter deletes a profile in which no new posts have appeared for more than six months. In other cases, pages change status. Facebook allows you to turn a user profile into a “memorial”. To do this, you need to send a copy of the death certificate to the network administration. The status of the page will change - the inscription “In loving memory of...” will appear, and you can continue to leave comments and entries on the wall. When changing status, access to personal correspondence is not transferred to either relatives or other close people. Your secrets will definitely remain yours forever. A single solution to the problem of the social network has not yet been developed, but in the coming years it is already worth having in stock: around 2050, the number of pages of the dead will be equal to the number of profiles of the living, and then the ratio will change in favor of the dead.
