Astronauts often level our planet from a cool place from the Black Sea. Such a great color is given to our Earth by water, which covers most of the planet. Although the water itself does not change color, it reflects the sleepy parts of the spectrum.
It is a familiar fact for everyone that our planet is largely covered with water. Dekhto comes up with the idea that our planet should be called not Earth, but Water and Ocean. Why is a part of the Earth made up of water? The answer to this question is complex, but it is difficult to understand.
In the simplest case, about 71% of the Earth’s surface is covered with water, and 29% of the continents and islands are covered.
To be more precise, 96.5% of all earthly water is located in oceans and salt seas, and the 3.5% that is lost is fresh water, found in rivers, lakes and ice fields. Also, water on Earth is present in the atmosphere in the form of water vapor and moisture. If you could melt all the ice reservoirs, and the surface of the Earth would be completely smooth, the plains of the seas would rise to a height of 2.7 km.
There is some water in ice reservoirs and freshwater reservoirs, and there is also water under the surface of the Earth - ground water. If it were possible to collect all the fresh water into one mass, then the result would be a water reservoir with a volume of approximately 1386,000,000 km3.
Nowadays, from the fresh water that is located in rivers, lakes and near groundwater, a volume of a total of 10,600,000 km3 would emerge, which would be less than 0.7% of all fresh water reserves. Having said that, fresh water, suitable for drinking, is truly the most valuable resource on Earth.
Hello, what part does water make up of the mass of our planet? It has long been believed that the total mass of water in all oceans is 1.35 x 1018 tons, which is 1/4400 of the total mass of the Earth. In other words, although the oceans cover 71% of the earth's surface, they become less than 0.02% of the planet's terrestrial mass.
The amount of water lying on the surface of the Earth, and the fact that there is more water near the Earth, even on any planet of the terrestrial group, remains a great mystery for everyone.
It was recently realized that the Earth was formed 4.6 billion years ago, making it look like a dry and hot planet. Consistent with this theory, water was brought to Earth by later comets and other trans-Neptunian bodies from the outer reaches of the Sonic system. However, having traced the meteorites that formed in different periods of the history of the Sonya system, we now come to the conclusion that water on the planet was present from the earliest days of formation, although it does not exclude that the bulk of the water was brought by comets and.
In the other half of the 20th century, due to the importance of many analysts, there was an effort to control resources, the main rank in carbohydrates. It seems that the shadow has lost such an important storehouse of human life as fresh water. It would seem that there would be no special sense in fighting through it, the axis out there is turning on the crane and scraping. Unfortunately, not all peoples are allowed to experience this great good. And then, literally within ten years, violent outbreaks on a planetary scale could begin.
How much water is on earth
The Earth has plenty of water; more than two-thirds of the planet’s surface is covered by it. The final obligation is to set the figure to 1386 million cubic kilometers. The trouble is not in how much, but how. The reserves of fresh water in the whole world are less than forty parts of the natural mass (approximately 35 million cubic km), all of which is used for drinking water and is used in various sectors of the population (agricultural, industrial, household) not due to high capacity kitchen salt (HCl) and other houses.
In addition, ensure that only one-hundredth of all reserves are considered accessible. The entire decision requires serious labor and material costs for production, cleaning and delivery of goods.
But it’s still not a problem: with the correct use of these resources and their rational, updated direction of essential obligations, it would have been exhausted forever. On the right is that fresh water in the world is distributed unevenly, its reserves are used up, they change, and the population of the planet grows. At present, there are approximately six and a half billion people alive on the planet, and according to the most modest forecasts, there will be more than 9 billion by 2050. Already, a third of the world’s population is suffering from a severe water shortage.
Geopolitical aspects
Part of the planet's population reaches the so-called “golden milliard” and has access to all the benefits of civilization that we consider normal (electricity, communications, telecommunications, water supply, sewerage, etc.).
By sharing virtually all resources and trying to preserve a high level of material wealth, countries with a damaged economy are living in order to prevent an increase in the level of life in this world. Fresh water today in some regions costs more than naphtha, and soon it will turn into a strategic commodity. The war that broke out in Libya, according to many estimates, became economical in nature for many reasons. Zokrema, having already established the gold standard for the dinar, the large-scale water pipeline project - once fully implemented - could take the entire Eastern African region out of the zone between the United States and Western Europe. Thus, it can be assumed that the natural resources of fresh water at this time pose a risk of military invasion no less than the naphtha birthplace.
What is water used for?
Water is a universal substance that can rightfully be called not only the source of all human blessings, but also its indispensable sink. Without it, it is impossible to grow the agricultural products of the country. For example, a kilogram of grain “costs” 0.8 – 4 tons of water (depending on the climate), and rice - 3.5 tons. It is the food industry that refueles the water. A kilogram of tsukru - be gentle, 400 liters. With modest physiological needs (just to drink, people consume two to three liters per day), a bag of red wine, together with products, contributes to up to three tons of water used for their production. Today.
In general, the planet’s fresh water is wasted like this:
- Sil'skogospodarska galuz - 70% of this valuable resource;
- all industry – 22%;
- household workers – 8%.
Ale tse, obviously, average performance. There are many countries where the population is not rich in gastronomic establishments, where the problem of fresh water is so severe that people sometimes simply have nothing to eat or drink.
The acidity of water in the “third countries”
Today, according to international standards, people need forty liters of water per day for all their needs, including hygiene. Approximately a billion inhabitants of the planet, however, can only die without dying, and another 2.5 billion feel the same in the other world. According to various forecasts, as early as 2025 there will be a large number of people who will need critical parts when fresh water becomes too rich for two out of every three earthlings.
We, with our wealth, are sometimes unable to discern what kind of water the inhabitants of the “third world” swim in and what kind of water they drink. Soon three million people are dying of illness caused by poor sanitary conditions. The main cause of them is diarrhea. Three thousand children all over the world (mostly in Africa) are dying because of it.
The cause of eight out of ten skin pathologies is the obstruction of fresh waters and their defects.
Ecological support for bio-burning plants
You don’t just drink water, you know the stagnation of the skin’s activity. Moreover, our planet is a closed ecosystem, and there are a lot of interconnected and interconnected connections in it. By regenerating or renewing one of the important resources, humanity is increasingly wasting the other, which, it seems, is still plentiful. So, for example, it is expected that the sphere of production of synthetic carbohydrates is expected to replace naphtha products. As an alternative to fuel, in which it is planned to increasingly use ethanol (also known as ethyl alcohol or alcohol), it is clear that it is more environmentally friendly, lower gasoline, diesel fuel or gas, in order to generate a ton of this product, consumption I'll say it again anyway fresh water, and in quantities larger than a thousand times. On the other hand, the biomaterial from the forests serves as the raw material for synthesis, and the technology itself is impossible without hydroresources.
Theoretical and practical matters
The availability of hydroresources in various countries and entire regions of the planet is significantly changing. The problem of fresh water is most severe in Africa and in the Middle East. Its scale can be assessed by looking around the dzherel, in addition, research is underway, and possible methods can be introduced into the field of vologists. Most of the water that is collected for irrigation, industry and everyday needs comes from surface or underground waters that are replenished through the natural circulation. There are also vast reserves that lie, for example, in the Libyan ancestry. The stench becomes approximately the fifth part of all water resources on the planet. There is no stench, there is practically nothing to be found in them, and in regions where there is a shortage, there are no alternatives to them. There is still ice on the planet, snow and deposits that look like icemen. Possible fresh water resources can theoretically be divided into the following categories:
1. Ice and snow – 24.1 million cubic meters. km (68.7%).
2. Ground water – 10.5 million cubic meters. km (30.1%).
3. Lakes – 91 thousand. cube km (0.26%).
4. Ground water – 16.5 thousand. cube km (0.05%).
5. Swamps - 11.5 thousand. cube km (0.03%).
6. Rivers – 2.1 thousand. cube km (0.006%).
The practical practice, however, differs greatly from theoretical possibilities. Of great importance is the availability of the resource and the ability to bring it to life. Ice fields, which create the largest supply of fresh water on Earth, are now deprived of non-victory water through the road. Desalination technologies are cheaper.
Distillation
Desalination, with all the energy intensity and high productivity of the product, needs to be expanded in countries close to the same time (Qatar, Kuwait, Saudi Arabia, United Arab Emirates), which lacks sufficient supply g budget funds for the implementation of large-scale projects. Overall, this strategy is justified, but the actions of uncontrolled barriers of a technological nature create the present problems. For example, Oman's water intake systems were recently found to be clogged with waste water, which paralyzed the operation of distillation plants for an alarming hour.
Recently, the largest regional supplier of fresh water has become the Turecchyna region, which has directed serious investments to this specific sector of the economy. The country has no problems with hydroelectric supplies and sells excess supplies to Israel and other powers, transporting them in special tankers.
Yak spoiling dzherela vod
As it often happens, the problem lies not so much in the lack of resources, but in the lack of mercifulness and the irrational choice of what it is. The largest rivers are transformed into giant sewage ditches, drained by waste industrial wastewater and household waste. However, the contamination of fresh waters, despite all its severity and obviousness, is not the whole problem.
In search of cheap ways to generate electricity, they are blocked by rowing, which is consistent with their natural flow and destroys the temperature-dynamic characteristics of vaporization processes. As a result, the rivers dribble. Such things are guarded against. Rhubarb falls in the Colorado, Mississippi, Volza, Dnieper, Yellow River, Hansa and other great rivers, and others dry up everywhere. Before the ecological catastrophe, the piece was handed over to the hydroelectric system of the Aral Sea.
Who draws water and who wastes it?
By all means, the largest supply of fresh water on the planet (about a third) is found in New America. It's still a quarter in Asia. 29 countries, united geographically, and, according to economic standards (free market and democracy of the entry point) into the OSER organization, account for one-fifth of the publicly available water resources. The powers of the entire USSR - over twenty hundred thousand. Rashta, which is roughly close to 2%, covers part of Nearby and Lower Africa. However, deal with the worst of it on most of the entire territory of the Black Continent.
Unfortunately, its greatest popularity is observed in India, China, USA, Pakistan, Japan, Thailand, Indonesia, Bangladesh, Mexico and Russia.
When the most water is wasted, it is not always in these regions, where the reserves are truly great. The domestic demand is met in China, India and the United States.
The situation with water resources in Russia
Russia is rich in everything, food and water. The brightest example of the treasure our country has is Lake Baikal, which locally contains a fifth of the planet’s entire water supply, including its miraculous value. However, most of the population of the Russian Federation lives in its European part. Baikal is far away, you can drink water from the nearest waters, which, fortunately, are also plentiful. True, the importance and rational focus on water (as well as all other) wealth, which was typical for the Radian period, has not completely survived to this day. I hope that soon this place will be straightened out.
In general, at the present moment and in the near future, the Russians will not be threatened by sprague.
Water on our planet is found in three forms - rare, solid (ice, snow) and gaseous (steam). At a given hour, water takes up 3/4.
Water creates the aqueous shell of our planet – the hydrosphere.
The hydrosphere (from the Greek words “hydro” - water, “sphere” - kula) includes three main storage areas: the ocean of light, dry water and water in the atmosphere. All parts of the hydrosphere are connected to each other by the process of water circulation in nature.
- Explain how water from continents flows to the Light Ocean.
- How does water get into the atmosphere?
- How does water drain water onto land?
The Ocean of Light contains over 96% of the total water on our planet.
Continents and islands share the Light Ocean, surrounded by oceans: Pacific, Atlantic, Indian, .
The rest of the maps show the Ice Ocean - the expanse of water that borders Antarctica. The largest by area is the Pacific Ocean, the smallest is the Pivnichny Ice Ocean.
Parts of the oceans that extend into the land and are affected by the powers of their waters are called seas. It's so rich. The largest seas on the planet are the Philippine, Arabian, and Korala seas.
Water in natural minds avenges various disorders in their speech. In 1 liter of ocean water in the middle there is 35 g of salt (mostly kitchen salt), which gives it a salty taste, making it inappropriate for drinking and vikoristan in industry and rural dominion.
Rivers, lakes, swamps, ice fields and underground waters - these waters are dry land. Most of the land waters are fresh, but some of the lakes and groundwater are concentrated and salty.
You know how important a role rivers, lakes, and swamps play in nature and people’s lives. It’s amazing: the total amount of water on Earth is very small - only 0.02%.
Much more water is stored at the ice dams – close to 2%. There is no need to get rid of this ice, which is created when the water freezes. They hang there, as more falls out, the bottom comes out. Little by little, the snow accumulates, thickens and turns into ice. Ice machines cover approximately 1/10 of the land. The stench grows forth from us, on the mainland of Antarctica and the islands of Greenland, which are covered with majestic creepy shells. sink the ice that has broken up along their shores, creating floating mountains - icebergs.
Their actions reach great proportions. Most areas are occupied by ice fields in the mountains, especially in such high ones as the Himalayas, Pamirs, and Tien Shan.
Ice fields can be called fresh water komors. It is not yet possible to get involved, but for a long time now, projects for transporting icebergs near dry areas have been developed in order to provide drinking water to local residents.
This is also about 2% of the Earth’s total water. The stench grows from the upper part of the earth's crust.
These waters can be salty or fresh, cold, warm or hot. Often the stench is infused with bark, healthy human liquids and medicinal waters (mineral waters).
In many places, for example, on the banks of rivers, in ravines, underground water comes to the surface, creating dzherels (they are also called dzherels and keys).
Groundwater reserves will be replenished by atmospheric precipitation, which will seep through the rock deposits on the surface of the earth. In this way, underground waters take their fate from nature.
Water in the atmosphere
Mix water steam, water droplets and crystals into ice. All at once the stench becomes part of the earth's filthy amount of water. Without them, it would be impossible to circulate water on our planet.

The water layer of the Earth is called the hydrosphere. They form the ocean of light, water on land and water in the atmosphere. All parts of the hydrosphere are connected with each other by the process of water circulation in nature. The Ocean of Light contains over 96% of the planet's water. We have to share across the oceans. The parts of the oceans that jut out from the land are called seas. Land waters include rivers, lakes, swamps, ice fields, and underground waters. The atmosphere contains water vapor, droplets of water and crystals of ice.

Water plays a vital role in supporting the vitality of any organism. This substance can be presented in three aggregate stages: solid, rare and gas-like. The heart itself is the main internal core of the human body and other organisms, because All biochemical reactions take place here, and all cellular structures are dissolved.
How many hundred square meters does the earth's water occupy?
After all, about 71% of water is taken up by water. The area is represented by oceans, rivers, seas, lakes, swamps, and icebergs. We warmly respect and steam from the atmospheric air.
At this rate, less than 3% becomes fresh water. Most of them are found in icebergs, as well as in rivers and lakes on the continents. How many hundreds of thousands of waters does the Earth have in its seas and oceans? This pool contains in places the accumulation of salty H2O, which becomes 97% of the salt water.
If it became possible to collect all the water on earth into one drop, then the sea water would take up approximately 1,400 million km3, and the fresh water would be collected from drops with a volume of 10 million km3. As much as possible, fresh water is 140 times less than salty Earth.
How many hundred square meters does the Earth occupy?
About 3% of the total area is occupied by fresh water. Most of it is concentrated in icebergs, in highland snow and groundwater, and a small amount falls on the rivers and lakes of the continents.
In the city, fresh water is divided into available and inaccessible. The first group consists of rivers, lakes, and also the earth's crust and atmospheric air vapor. All people have become accustomed to pursuing their own goals.
How many hundreds of hundreds of fresh waters will the Earth have before it is inaccessible? In front of us there are great reserves of icebergs and mountainous snow covers. The stench itself becomes most of the fresh water. Also, the deep waters of the earth’s crust form the remaining portion of all fresh H2O. Neither one nor the other, people have not yet learned to become victorious, but this has great merit, because People can still competently manage such an expensive resource as water.
in nature
Natural circulation plays a great role in living organisms, because water is a universal dispenser. It is the main internal core of creatures and plants.
Water is concentrated in people’s bodies and other sources, and in water basins: seas, oceans, rivers, lakes, swamps. The circulation of the garden begins with the fall of rainfall such as rain and snow. Then the water accumulates, and then evaporates under the influence of acid. It is brightly noticeable during dry and hot periods. Due to the circulation of water in the atmosphere, it is possible to determine how many hundreds of hundredths of water on the earth are concentrated in solid, rare and gas-like substances.
The circulation is of great ecological importance, because fluid circulates in the atmosphere, hydrosphere and earth’s crust, and thereby self-cleanses itself. In some ponds, the village is dammed with water, the water level is high, this process is of great importance for supporting the vitality of the organisms of the ecosystem, and the restoration of high purity takes a long period of time.
Drive around
The riddle about how fresh water appeared cannot be solved for a long time. However, the scientific community has come up with a number of hypotheses that suggest options for the creation of nature.
One of these guesses dates back to the hour when the Earth was born. It is associated with the falls of “wet” meteorites, which could bring water with them. The water accumulated in the depths of the Earth, which gave rise to the first hydrated olon. Because of the ever-impossible supply of food, how many hundreds of thousands of waters of the Earth lay in that distant hour.
Another theory is based on the earthly movement of water. The main reason for the formation of this hypothesis was the discovery of a high concentration of the important water deuterium in the seas and oceans. The chemical nature of deuterium is such that it could deprive the Earth of an increase in atomic mass. Therefore, it has always been respected that the home of the Earth has settled and there is no cosmic exploration. However, researchers who support this hypothesis still cannot provide information on the supply of how many hundreds of waters there were on Earth, 4.4 billion years ago.
Water Speech is necessary, as it is required for the basis of life. People have always respected the fact that water appeared on Earth after the formation of the planet. Some theories suggest that this country was destroyed by meteorites that were covered with ice.
I appreciate it water occupies 70.8% of the Earth's surface. For these reasons our Earth is called “Planet of Water” or “Planet of Ocean”. The surface area of the planet is 510 million km2, and the ocean covers 360 million km2. Also, don’t forget about the ice fields, which cover 16.3 million km2. Swamps, dry land, lakes, watercourses and other fertilized lands occupy approximately 5 million km2. Therefore, we can say that about 75% of the surface of the Earth is covered with water (3/4 of the Earth is occupied by water).
Also remember about the winter snow cover. The snow cover of Pivnichna Pivkuliya covers the largest area - 59 million km2. In this period, the area occupied by the hydrosphere was approximately 440 million km2, or more than 85% of the surface of our planet. In winter, snow falls, which covers large areas - roads, highways, streets, stitches, sidewalks.
In 2002, a group of Japanese scientists conducted an experiment in which they discovered that under the Earth, in its lower mantle there is 5 times more water than on the surface.

How much fresh water is there on Earth?
Seas, oceans, rivers and lakes cover 70% of the Earth's surface area, with land occupying the majority. The largest ocean on the planet is the Pacific. The maximum depth of this giant is 11.8 km. In the middle, the depth of the oceans reaches 3800 meters.
All living things on the planet will require water. Fresh water becomes less than 3% from all the Earth's water reserves, and 97% is salt. Today's largest fresh lakes are Onezka, Baikal, Dolonezka, Kaspiiske. Atmospheric precipitation is also the main supplier of fresh water to the Earth.
