Water is the basis of everything, it gives life to all organisms on our planet. This is her main advantage, and this is her beauty. Without jewelry, you can safely live your whole life, without food you can hold out for several weeks, and without water, life will be limited to a maximum of a week. There is no substance more valuable than water. And at the same time more “smart9raquo;”.

The beauty of water lies in its ability to respond to music, mood, good and evil words. It is known that crystals of this substance seem to absorb energy and create a variety of forms. Scientists have repeatedly carried out experiments on water. One was that the words "thank you, love, gratitude, angel" were spoken in different languages. And each time, incredibly beautiful crystal shapes were formed. Then the words "fool, I will kill, devil" were pronounced, but as a result nothing beautiful was observed. The crystals turned out to be incomprehensible and blurred. The water seems to have a soul that reacts to everything that happens around.

The water is insanely beautiful in the sun. How beautiful are streams, rivers, waterfalls! Beauty is where there is water. Even one drop, even a small dewdrop shimmers with hundreds of colors. I remember how as a child I was always happy about the snow, because when the sun came out, it seemed as if everything was covered with diamonds. Every winter turned into a fairy tale for me. And who among us was not happy with snowflakes, looking at them on his mitten? Thousands of options, and no two are alike, each is good in its own way. Isn't that a miracle? We are no less pleased with the patterns on the windows in winter, and the mysterious fog in the morning. Water is beautiful in any condition, and this is its peculiarity.

For me, water is a living being. It is better than any mirror. What you give is what you get. It is not for nothing that our ancestors believed in her power. Living water exists. This is the one to whom we show our good feelings, and who then passes this good on to other people. Here's another facet of her beauty.

Water can be warm or cold, fresh or salty, solid, liquid or gaseous. But she is amazing in any condition. Save water, it is our life.

Water in human life

In our daily life, we are constantly exposed to water. At the same time, paraphrasing a song from an old movie, we can say that we "drink water" and "pour water". We will talk about these two aspects of human water use.

By itself, water has no nutritional value, but it is an indispensable part of all living things. Plants contain up to 90% of water, while the body of an adult consists of about 60 - 65% of it. Having gone into the details, it can be noted that bones contain 22% water, the brain 75%, while blood consists of it as much as 92%.

The primary role of water in the life of all living beings, including humans, is due to the fact that it is a universal solvent for a huge amount of chemicals. Those. in fact, it is the environment in which all life processes take place.

Here is just a small and far from complete list of "responsibilities9" of water in our body.

Regulates body temperature.

Provides the delivery of nutrients and oxygen to all cells of the body.

Protects and buffers vital organs.

Helps convert food into energy.

Helps nutrients to be absorbed by the organs.

Displays slags and waste of vital processes.

A definite and constant water content is a necessary condition for the existence of a living organism. When the amount of water consumed and its salt composition changes, the processes of digestion and assimilation of food, hematopoiesis, etc. are disrupted. Without water, it is impossible to regulate the heat exchange between the body and the environment and maintain body temperature.

A person is extremely sensitive to the change in the water content in his body and can live without it for only a few days. With a loss of water in an amount of less than 2% of body weight (1-1.5 l), a feeling of thirst appears, with a loss of 6-8%, a semi-faint state occurs, with 10% - hallucinations, impaired swallowing. Loss of 10-20% of water is life-threatening. Animals die when 20-25% of water is lost.

Excessive water consumption leads to overload of cardio-vascular system, causes debilitating sweating, accompanied by loss of salts, weakens the body.

Depending on the intensity of work, external conditions (including climate), cultural traditions, a person in total (together with food) consumes from 2 to 4 liters of water per day and the same amount of water is excreted from the body (for more details, see "Drinking regime and balance of water in the body "and the article" To drink or not to drink - that is the question "from the magazine" Health9 in our "Digest9). The average daily consumption is about 2-2.5 liters. It is these figures that the World Health Organization (WHO) proceeds from when developing recommendations for water quality (See "Water quality parameters").

The mineral composition of the water is also important. Fresh water with a total mineralization of up to 0.5 - 1 g / l is suitable for constant drinking and cooking. Although, of course, in limited quantities it is possible (and sometimes even useful, for example, for medicinal purposes) the use of mineral water with a high salt content (about which water "is suitable9 for which diseases, see the article" Every disease has its own water "in our" Digest9quot " ;). The human body quickly adapts to changes in the salt composition of drinking water. However, the process of getting used to it takes some time. Therefore, with a sharp (and even more frequent) change in the characteristics of water, disturbances in the activity of the gastrointestinal tract, popularly known as the "disease of travelers", are possible.

In general, the question of what nutrients and in what quantities should be contained in water is given a lot of attention in the media. This problem is really very important, but, unfortunately, there is too much speculation and profanation around it.

Even very reputable publications allow themselves to publish somewhat irresponsibly information such as: "a person gets up to 25% of useful minerals from water" and other, to put it mildly, information that does not fully correspond to reality. Classics of the genre "I heard the ringing, but I don't know where it is" - article "Capital water." By Mrs. Ekaterina Bychkova in "AiF-Moscow9 №37" 99.

Our point of view on this issue can be found in the section "Water and useful minerals".

It is well known that the use of water for domestic purposes in Russia is far from rational (we will tactfully keep silent about industry for lack of reliable data). There are two main reasons:

Abundance of water resources.

In its issue of August 31, 1999, devoted to water problems, the journal "Itogi9" presented illustrative data characterizing these two parameters and their relationship.

It can be seen that the cheaper water is in one country or another, the more generously it is poured. It is also not surprising that in Russia, where before recent years there was no practice of installing water measuring devices for each apartment, and there are no reliable statistics on water consumption in everyday life.

Therefore, we will use published English data from the mid-80s. Of course, in the UK, the daily water consumption per capita at that time was already 140 l / day, and we still have it in the region of 400 l / day, but the data collected by the meticulous British are so interesting that we should study and take note of them ... In any case, the market economy dictates its own laws, it is likely that soon water will rise in price and the frugality of the aforementioned Englishmen will no longer seem unfounded to us.

So. According to English data / 15 /:

The main item of water consumption in everyday life is the toilet. The "gentle contralto of a water tank tool" is responsible for 35% of water consumption per head per day (50 liters). This is followed by personal hygiene (taking a bath and shower, washing, etc.) - 32% of the consumption (45 liters), washing - 12% (17 liters), washing dishes - 10% (14 liters), drinking and cooking - 3% (4 liters), other expenses (pets, watering flowers, etc.) - 8% (11 liters).

It is clear that these figures are averaged and reduced to one day (for example, a person does not take a bath and wash every day). However, they also provide food for thought and comparison with our reality.

It is unlikely that we eat much more than the same Englishmen and, accordingly, we also spend about 4 - 4.5 liters per head per day on cooking. Yes, they will forgive us for such a conclusion, but from the previous one it directly follows that we should not use the toilet more often (or are there other opinions?). Considering that we have the same European standard for flush tanks, this gives the same 50 liters.

By the way, the meticulous British calculated that a family of two adults and three children uses the toilet on average 25-40 times a day. If there is a habit of flushing food residues and other waste into the toilet, then the number of "flushes9 even in a family of 4 people can reach 60. Here, by the way, one should look for the origins of the ecological the initiative "Give a brick in the toilet cistern!" Joking aside, they put a brick in the cistern, thus reducing the volume of water in it by almost 2 liters. Multiply by the number of flushes per day and get "clean9 savings. And if we are talking about such an interesting sphere of human life as a toilet, then the future belongs to vacuum units (like those installed in airplanes), which consume only 1 (one) liter of water per session.

But back to our rams. We would also venture to assume that in terms of washing automation we have nevertheless reached the level of England 15 years ago, and for these purposes the average per capita consumption is 17 liters.

Where then, as our first president used to say, "the dog rummaged"? Why do we use 2 times more water?

To do this, let's see what is left of the water consumption items: personal hygiene, washing dishes, and more. Here, probably, lies the key. Not that we washed ourselves more and washed dishes more thoroughly. The difference is rather that we do not have the habit of turning off the tap when, for example, brushing our teeth, and we also wash dishes in running water. It would seem - a trifle, but keep in mind that 10-15 liters of water flows out through an open tap per minute. And the second powerful "reserve9" is the position "Other9quot ;. The fact is that "they" have practically no such article as leaks in this section. Their life simply makes them quickly fix the current plumbing - not only water is flowing, money is flowing. We can say with good reason that in our conditions the lion's share of leaks occurs precisely in houses, so to speak, "after the meter." And that's why.

The British pay great attention to leaks, but due to the stated reasons, their main leaks occur in the municipal water supply network. In Moscow, according to experts, 15-16% of water is also lost between the water intake station and the apartment (see the article "Moskovskie Vodokhlyobi", Zh-l "Itogi9quot ;, 08/31/99). And now, attention, the most important thing. what is bad, but just an excellent result! In England, losses are on average 25% and their specialists, recognizing the inevitability of leaks, believe that the really achievable result, which one should strive for in terms of leaks, is 15%. What, as they say, was required To prove it. Honor and praise "Mosvodokanal9quot ;. We suspect, however, that on average the situation in the country is closer to the English one. Nevertheless, even if this is so, it still shows once again where we are suffering losses. Unfortunately, we are accustomed to blaming everything on the water supply, but it turns out that "there is nothing to blame on the mirror." It's time to understand that after the pipes have entered the building (be it a residential building, office center or industrial facility), the responsibility lies with the owners and users.

So, you look - in the near future, and we will need a brick in the toilet cistern and other "bourgeois" tricks. As the same English say: "Forewarned is already armed."

Attention, only TODAY!

Stories about water for a child should be fun and exciting! Knowledge about water is necessary if, along with other components necessary for the proper development of the personality, you pay attention to such a component as the education of ecological culture. Today, fostering the right attitude to nature and the resources that we use is one of the main tasks of preschool and general education institutions. In the process of working on ecological culture, children need to be told about water. After all, it is water that is the basis of life on Earth, without this resource a person cannot exist, and the limited supply of fresh water makes whole peoples seriously think about this problem now.

How to tell children about water?

The choice of topic and the way of storytelling depends on the age of the children. Usually, special educational cartoons are used for preschoolers. So children can better master the material, perceive information, it is easier for preschoolers from the lips of the main characters of their favorite cartoon than in a regular lesson.

For school-age children, it is possible both in regular classes and in non-standard forms. For example, you can experiment with water in the context of a certain discipline, watch scientific films about water. It is important to choose the right material and bring really important and interesting information to the children.

What to tell children about water?

A story about water for school-age children should involve interesting facts and uncover previously unexplored questions.

Water is the basis of life on our planet. At the same time, this substance is one of the most abundant on Earth. But the reserves of fresh water are still not very large, some countries are already experiencing great difficulties in providing the population with water, and people there have to save every liter of water.

Watch the video film "About water for a child":

Man is 70% water. Some inhabitants of the underwater world are 99% water at all. This once again confirms the theory that life appeared precisely in water and only millions of years later, through evolution, could it come to the surface.

Despite the prevalence of water on Earth, finding it outside of our board is quite problematic. If it is on other celestial bodies, it is only in small quantities or in the form of water with impurities of debris.

Scientists suggest that the presence of such an amount of water on Earth speaks of the turbulent history of the planet's development. According to experts, such water reserves could have formed only as a result of numerous collisions of comets with the Earth. Comets are mostly composed of water ice and cosmic dust.

A person can live without water for only a few days. Water is the basis for many processes in the body. For normal life, the human body needs 1.5-2 liters of water daily.

In this lesson we will talk to you about water. Is there a lot of water on Earth? What role does it play in the life of animals, plants and humans? What properties does water have? We will consider these and other questions with you in the lesson.

Theme: Nature

Lesson: Water

Let's remember what phenomena of inanimate nature water is associated with. Dew, fog, cloud, steam, rain, snow, ice, frost are all water.

Figure: 1. Water

Water on the globe and on the map is indicated in blue. This color is the most on the globe, because ¾ of the Earth's surface is covered with water. There is water everywhere. Our globe is enveloped in a thick layer of air, and there is also a lot of water, steam, clouds, clouds in the air. There is water underground - these are springs. Huge accumulations of ice are found at the north and south poles of the planet, and ice is water.

Water is part of all living organisms. If you remember a green leaf in your hand, you will find moisture. Water is found in all parts of plants.

Remember how much juice is found in fruits and berries. Juice is also water with substances dissolved in it.

Figure: 2. Fruits and berries

Even dry seeds of plants contain water, although in much smaller quantities.

Figure: 3. Plant seeds

The Italian artist Leonardo da Vinci called water the juice of life. And it is true. If we don't water the plants, they will dry out.

In the body of animals, water usually makes up more than half of the mass, and the body of a jellyfish is 90-95% water.

A person can live only 3 days without water, and 30-50 days without food. The person himself is 2/3 water. Water is part of human blood. Water evaporates from the surface of the skin and thus regulates our body temperature. Water removes harmful substances from the body. Fields and forests need water, and neither animals, nor birds, nor people can live without it. Water not only gives water, but also feeds. A huge number of fishing boats sail across the seas and oceans. Water generates electricity when it works in power plants. Water washes everything in the world. And also water is the largest and most convenient road. Ships go along it day and night, carrying various goods, passengers. All this became available to man only after he studied the properties of water.

Let's take a look at them:

1. Water takes the form of the vessel in which it is located;

2. Water is a transparent liquid;

3. Water flows, moves. This property is called fluidity;

4. The water is odorless;

5. Water has no taste;

6. Water is a solvent, but not for all substances.

Water is life, and people pollute it with waste from factories and factories. To prevent this from happening, it is necessary to build treatment facilities, water must be used carefully and economically.

Hello dear blog readers! World Water Day is celebrated annually on March 22 by the decision of the UN General Assembly. The purpose of this holiday is to remind all mankind of the importance of water for environment and human life. Perhaps, having learned a little more about our well-known water, we will think about the need to save it. Amazing and little-known facts about water are the topic of our conversation today.

Our planet Earth is 70% covered with water, 3% of the total mass is fresh water, the rest of the water is sea water and glaciers. Only 1% is used for drinking.

Throughout our life, we are so accustomed to water that we do not even notice how necessary it is for our life. And how many secrets and mysteries it conceals in itself! Scientists are still studying it, finding more and more interesting facts. We will talk about some of them today.

Water plays a huge role in human life. The human body is 70-80% liquid, most of which is in the extracellular fluid. From the intercellular space everything nutrients, vitamins and minerals are absorbed into the cell, supporting its functioning.

And, conversely, all waste substances from the cell are returned back to the intercellular space. If for some reason the timely disposal of waste substances does not occur, then the cell begins to consume its own waste. And the pathological process starts, which leads to the development of various diseases.

This process can be normalized if you drink enough clean water. Every day, our body excretes up to 2.5 liters of fluid with sweat, urine and feces. In order for all physiological processes to proceed normally in the human body, it is necessary to consume the same amount of pure water.

Water also participates in the process of thermoregulation and respiration.

Did you know?

We remember from school that clear water has no color, smell or taste; it freezes at zero degrees and boils at 100 degrees Celsius. We also know that it has 3 states of aggregation: liquid, solid, when it freezes and turns into ice, and gaseous - in the form of vapor.

Someone may know that when mixing water with alcohol, the mixture heats up. However, there are many more interesting facts that hardly anyone knows about. Here are some of them.

At a temperature of minus 120º, water acquires unusual properties: while remaining solid, it simultaneously becomes very viscous and becomes viscous. And if you still cool the water down to minus 135º, then it will change the crystal structure to a glassy one.

Already proven by a student from Tanzania that hot water freezes faster than cold water! E.B. Mpemba discovered this phenomenon back in 1963. He put in freezer 2 glasses of water, one with hot water, the other with cold water. And with surprise he noticed that hot water froze faster than cold water. He told his physics teacher about his discovery, to which he replied that this was simply impossible. But they repeated the experiments with the freezing of water more than once, but they did not find an explanation for this.

Living and dead water

We remember the tales of living and dead water, where dead water helps to heal wounds, and living water brings back to life. These properties of water have been studied for a long time and it has already been proven that with the help of the information received, water acquires special properties. Depending on the environment, water absorbs both positive and negative information, while changing the structure of the molecules.

It is believed that "living" water is thawed water, and "dead" water or the one that is taken for Ivan Kupala. "Dead" water, despite its gloomy name, helps to relieve inflammation and heals from terrible diseases. It is not for nothing that earlier, and even now, people bathe in the Epiphany ice hole for healing.

An interesting experiment was carried out. We took 2 containers of water. Hard rock music was played next to one tank, and classical music next to the other. As a result, it turned out that the structure of crystals, which "listened" to heavy rock, had an ugly and uneven structure, and the one that "listened" to the classics had water crystals even and beautiful outlines.

Something similar happens if sorceresses or sorceresses slander the water for "bad" or "good". Having drunk such water, we get sickness or, conversely, heal. It seems that all this is nonsense, but my own life experience suggests that this is really so.

To remove negative information from the water, it is recommended to freeze the water and then thaw it, since when it freezes and then thaws, the water erases all negative information and becomes clean and promotes health, increasing immunity.

Another example of water, charged with negative, if swearing next to it. Watering the seeds with such water, the seeds germinated only half. And if you water the seeds with "holy" water, the germination rate reached 90%. With the help of "holy" water, bad energy in the room is purified, therefore, especially on the feast of Epiphany and Easter, it is recommended to sprinkle the dwelling with such water.

• On the territory of Algeria there are lakes of ink, with such water you can easily write on paper. And in Azerbaijan there is a lake with methane, from a lit match the water lights up with a blue flame. And in Sicily there is a lake that is fed with concentrated acid from 2 sources, such a lake is dead, it lacks all living things.
• There is a lake in Antarctica, the concentration of salts in which is 11 times higher than in sea water. Such water can freeze at a temperature of -50º.
• According to UNESCO, the cleanest water in 122 countries where water is studied is water in Finland. And 1 billion of the world's inhabitants have no access to safe water at all.

• A person without water can live no more than 6 weeks. A person feels thirsty if the water loss is 2%. With a loss of 10% water, a person begins to hallucinate. The loss of 12% of water can still bring a person back to life if doctors help him, but the loss of 20% is already becoming fatal for a person.
• Everyone knows the formula of water - H2O. Such pure water exists only on paper. In fact, water is a universal solvent capable of dissolving a wide variety of substances and minerals. Depending on the origin and the dissolved substances in it, about 1330 types of water are known. It can be spring water, melt water, rain water, soil water, etc.
• The human body is 70% water, the animal's body is about half. And 99% consists of jellyfish water.
• Water is considered one of the best conductors of electricity. But by itself, pure (distilled) water is not a conductor; molecules of impurities and ions of various minerals dissolved in water conduct electricity. This must be taken into account if you swim during a thunderstorm, when there is a possibility of lightning striking a body of water, and this is already life-threatening.
• Water is not only a source of vitality. Water can serve as a carrier of various microorganisms that can lead to very serious diseases, such as cholera, typhoid fever, viral hepatitis A, rotavirus infection, etc. Up to 25 million people die from these diseases every year.

• In one children's book there is even such a rhyme: "Close the tap tightly so that the ocean does not flow out." If you don't close the tap tightly, then 840 liters of water can "drip" in a day.
• Drinking too much water can increase arterial pressure, but at the same time, it is the best way to get rid of edema. And drunk 2 liters of pure water a day will help get rid of depression and fatigue. With the help of water, you can lose extra pounds if you give up sweet soda, tea or juices, and drink ordinary water.
• The largest amount of water, of course, is found in the oceans. However, the Earth's mantle contains 10-12 times more than the ocean.
• Most of the fresh water reserves are inaccessible to us, since it is contained in glaciers.
• In 1 cubic meter m of sea water contains 1.5 g of protein and other substances that are very nutritious. It has been calculated that a similar crop of the Atlantic Ocean alone, in terms of its nutritional value, can collect 20 thousand crops in the entire land per year.

Conclusion

Scientists around the world are sounding the alarm, their forecasts are disappointing: by 2025, the population of our planet, which is 3 billion people, will experience an acute shortage of drinking water. And without water, life on the planet can simply disappear. Therefore, humanity should now think about the careful attitude to water resources, look for solutions to preserve them. May our distant descendants enjoy life on our planet.

Water for us is the most familiar and simple substance. At the same time, water is fraught with many mysteries. Scientists are still continuing to study water, finding more and more interesting facts.

If a child suddenly has a drop in school performance, this does not always mean an overload. Lead in the water may be to blame. Excess fluoride leads to diseases of the musculoskeletal system. And what horror stories can be cited many. Therefore, today more or less educated parents explain to their children that:

In no case should you drink water from the tap;
- you can drink only filtered water;
- if there is no filter in the house yet, then it is necessary to settle the tap water during the night so that chlorine will escape from it;
- you cannot boil water more than once, when boiling again, dioxin, a poisonous substance that causes cancer, is released.

The last point seems especially surprising, since many have the habit of boiling water again.

Drinking water is of the first (table water) and the highest category.

Water of the first category is ordinary purified tap water, as well as obtained from surface sources. Yes Yes. But at the same time, the manufacturer must write on the label that this is "purified water from a central water supply source." It is softened, chlorine and excess iron are removed. At the end of the process, the former tap water is again disinfected and made useful: various useful trace elements are added, for example, calcium and magnesium.

Water of the highest category - it is extracted from underground sources, which are most protected from pollution. Such water must also be safe. But there is an additional criterion - the water of the highest category should be useful for the body. In scientific terms, it is physiologically complete. Compounds of fluorine, iodine, potassium are already present in it or are introduced after disinfection.

Mineral water
According to SanPin in Russia, natural mineral drinking table water can be consumed in unlimited quantities. But it turns out - it's unhealthy. The EU Directive "On Natural Mineral Water" states that such water contains many types of microcomponents in excess, and this is fraught with complications. So, do not experiment - especially on children.

“The name of the water, its type (first category, highest, etc.), date of manufacture, storage conditions, mandatory expiration date, chemical and physical composition of water (content of anions and cations, total mineralization, hardness) must be indicated.

Water is a necessary condition for the existence of all living organisms on our planet. "Water is more valuable than gold" - believed the Bedouins, who roamed the sands all their lives and knew the value of a sip of water. They understood that no amount of wealth will save a traveler in the desert if the supply of water runs out.

Water is one of the most basic human needs. Only oxygen is more important, without which life is simply not possible at all. Without water, a person can live only 2-3 days, but without food, you can last almost 3 months.

Water must be treated very carefully, because there is not so much water suitable for drinking on Earth. Despite the fact that water covers 3/4 of the Earth's area.

How much do we know about water? Interesting Facts for children and adults

Fact. A person can live without water for no more than 2-3 days.

Fact. A slight dehydration of the body (about 2% of the weight - about 1.5 kilograms), leads to unpleasant symptoms: loss of strength, fatigue.

Fact. Dehydration can be caused not only by physical activity, but also by overeating.

Fact. If the human body loses more than 10% of water, it can lead to death.

Fact. On average, according to statistics, the body of animals and plants contains more than 50% water.

Fact. Our body is 65-70% water.

Fact. The composition of the Earth's mantle contains 10-12 times more water than the World Ocean.

Fact. The oceans cover approximately 71% of the planet's surface, with an average depth of 4 km, and contains 97.6% of the world's known free water reserves.

Fact. If all the glaciers melted, the water level on our planet would rise by 64 m (approximately from a 20-storey building) and, about 1/8 of the land surface, would be flooded with water.

Fact. Water is the only substance in nature that is freely found on Earth, the density of which in the solid state is less than in the liquid state. That is why ice does not sink in water, and reservoirs, as a rule, do not freeze to the very bottom (although this is possible at extreme temperatures).

Fact. Sea water freezes at -1.91 ° \u200b\u200bC.

Fact. A person consumes about 60 tons of water in one year only in the process of feeding.

Fact. Water sometimes freezes and at above-zero temperatures.

Fact. Water has the highest heat capacity in comparison with naturally occurring liquids.

Fact. In nature, there are about 1330 types of water. They are distinguished by their origin (soil, rainfall, fresh or long-standing snow, etc.), by the nature of the substances dissolved in it and their quantity.

Fact. The surface tension of water of all natural liquids is second only to mercury.

Fact. We know about 3 different states of water (liquid, gaseous and solid). Contrary to this opinion, scientists distinguish 5 states in liquid form of water and 14 states in solid form.

Fact. Water is a versatile solvent.

Fact. Approximately 520 thousand cubic kilometers of water evaporates from the Earth's surface during the year. Rain and snow bring about the same amount of water to the Earth. If you imagine it visually, you get a cube with a side of about 80 kilometers. If this volume is distributed evenly over the surface of the Earth, then a layer about 1 meter thick will turn out.

Fact. Hot water freezes faster than chilled water. If you take two identical containers of water, hot and cold water, and place them in the freezer, then the container with hot water will freeze faster than cold water, although logically it should be the other way around.

Fact. The ocean occupies 3/4 of the entire surface of the Earth, while it is a powerful softener of the Earth's climate, constantly heating the lower atmospheric layers.

Fact. Water is transparent only to visible rays and strongly absorbs infrared radiation.

Fact. About 80% of the Earth's surface is covered with water and only 1% of this water is suitable for drinking.

Fact. In different parts of the Earth, ice has different temperatures. The coldest ice is in Antarctica (ice temperature -60 degrees). The ice temperature in Greenland is only 28 degrees, while the Alpine ice has a temperature of 0 degrees.

Fact. Glaciers contain the bulk of fresh water.
