The sun illuminates the earth. It shines even when we do not see it behind the clouds. The most cloudy day is still a day. And only when the sun disappears behind the horizon, night comes, darkness. this web page

The sun warms our earth with its rays. Even through the clouds, its warmth penetrates. And on the most cloudy day it is still warmer than at night. When the sun disappears below the horizon, the air begins to freshen up, and by the end of the night it usually cools down. This means that light and heat depend on us from the sun. But why doesn't the sun always give the same heat? We all know: in the morning it heats weakly, during the day it bakes strongly, in the evening it heats less again. The same can be observed at different times of the year. In winter, the rays of the sun, even on the clearest day, warm little. In the spring they begin to warm up more strongly, and in the summer they bake so that people try to hide in the shade.

Maybe during the day the sun is closer to the earth, which is why it warms more? Maybe in the summer it approaches us, and in the winter it moves away? No, this cannot be. After all, the earth rushes around the sun at almost the same distance from it.

From all this we can conclude: the rays of the sun heat the most when they fall vertically (at a right angle); they heat less if they fall obliquely (under acute angle). They give the least amount of heat when they slide over the surface of the earth. This happens in the morning and in the evening when the sun stands low on the horizon.

The sun is the main source of life on planet Earth. It is the closest star to us. Others are so far away that their light only reaches us millions of light years away. And if the Sun stops radiating its energy, all life on the Planet will definitely die.

Surely each of us at least once asked the question: “Why, in fact, in summer we sunbathe from sunlight, and in winter the same light is not even able to melt the ice a little?” So, let's figure it out.

How the sun works

Studying the Sun is a very difficult task. It is impossible to send aircraft to him, as they will simply burn out. But modern science there are many other ways to study an object that is far away, but radiates colossal energy at the same time. The distance to the Sun from Earth is 150 million km. It is this distance that allows life on our planet to exist comfortably.

In diameter, the core of the Sun reaches 175 thousand kilometers. The temperature inside the star is 14 million degrees Kelvin, and its causes are thermonuclear reactions. We can say that this is a kind of nuclear furnace. All the heat is generated in the core of the star, which then passes through several shells:

• the photosphere is the first layer above the nucleus, but the energy of the deeper layers does not reach here;
• spicules are regular ejections from the next layer of the Sun;
• The crown is the outermost shell of a star.

Interesting: prominences form in the corona. It is this shell that is the cause of the solar wind, which spreads to the most distant corners. solar system.

Visible light and solar energy are infrared rays and ultraviolet, as well as electromagnetic waves, radiation and x-rays.

Important! All these waves reach the Earth and other planets of the solar system and in a certain way affect them, and especially those of them where there is an atmosphere.

Influence of rays

All living things are affected primarily by UV rays. It is from their intensity ozone layer protecting our planet. The effect of ultraviolet rays on living organisms is manifested in the following:

• they contribute to the metabolic processes in the human body;
• thanks to this radiation, vitamin D is produced in the body, and without it a normal human life is impossible;
• increased blood flow;
• tan appears.

UV rays also have a positive effect on the atmosphere. They purify it and make it more favorable for life. Infrared rays also have a thermal effect. Thanks to them, the surface of the Earth is warm. But although these rays affect the atmosphere, there are times when their influence becomes minimal.

In winter, the sun heats less

In winter, the Sun does not heat as intensely, but this phenomenon can be explained from a scientific point of view. There is a decrease in the flow of solar heat to the Earth for the following reasons:

• the sun is very low above the horizon, so the rays travel a longer path through the atmosphere;
• in the morning and in the evening, for the same reason, it is not so hot, but in the evening it gets cold;
• cold wind shortens the period of heat that the sun can give us;
• In winter, the days are shorter and the nights are longer, which means that the period when infrared rays can affect the atmosphere is greatly reduced.

Of no small importance is the fact that in winter the surface of the earth is covered with white snow, which perfectly reflects the sun's rays, therefore general temperature decreases on the surface.

As we can see, although the Sun shines in winter, it is not necessary to expect a tan from it.

Seeing the sun shine is a good event.

Seeing the sun that has just risen in a cloudless sky is a great happiness.

You swallow the sun or the moon - a noble heir should be born.

Bowing with reverence to the sun or moon - portends great happiness and prosperity.

Clouds suddenly cover the sun - secret machinations, vile deeds.

Clouds dissipate, the sun appears - an unfortunate situation will be resolved

Sitting in a boat, look at the moon or the sun - an appointment.

The sun enters your chest - a noble son will be born (the moon is a daughter).

The sun and moon are about to appear in the sky - you will receive a post.

The sun and moon illuminate your body - you will receive an important position.

The sun and moon are falling from heaven - grief, you will lose your parents.

The sun and moon are hidden behind the mountain - the servant is deceiving the master.

The sun and moon unite - the wife will give birth to a son.

The sun and the moon grow dim - the wife suffered.

The sun and moon that have just appeared in the sky - prosperity and prosperity in the family.

The sun shines directly into the room - you will get a good position in the service.

The sun through the rain is a lucky break.

The sun in a dream can also mean a father.

Interpretation of dreams from the Noble dream book

All human life on earth is subject to the sun.

The religions of the ancient peoples placed the sun at the center of the universe.

Therefore, the sun has firmly entered the unconscious area of ​​\u200b\u200bman, as the main symbol.

Even the first soothsayers and dream interpreters noticed that the appearance of the sun in a dream portends success, honors.

And all other dream events taking place in the background sunny day bring auspicious tidings.

Modern people are more remote from nature than primitive tribes.

But at the level of unconscious feelings, we all have a mystical participation with nature.

Highest success, ardor in the implementation of the project, pleasure from life situation.

It symbolizes spiritual activity, ardor in the implementation of the project.

To see the sun in a dream is to have pleasure in a life situation, a bright mind.

It is symbolically depicted by various round figures: a disk, a wheel, a circle with a dot in the center.

These figures seen in a dream can also be correlated with the sun.

Very often in a dream we do not see the sun as a whole, but only sunlight.

Otherwise, just a beam of light.

This is the personification of a force capable of dispersing evil and darkness.

In more modern understanding a ray of light is concrete, analytical knowledge.

And it is known that knowledge in a dream is a preemptive, prophetic knowledge.

Therefore, one should with special confidence relate to the events of a dream illuminated by sunlight.

Interpretation of dreams from

The sun radiates energy in all directions. The amount of this energy is very large. Part of it reaches the Earth.

On the path of solar energy to the surface of the Earth is the atmosphere. It absorbs some of the energy, some passes to earth's surface, and part reflects back into space. The atmosphere absorbs about 17% of the energy, reflects about 31%, and transmits the remaining 52% to the Earth's surface.

It should be understood that when they say “absorbed and reflected” by the atmosphere, it means not only that the air does it, but also clouds, dust particles and more.

That solar energy that has passed through the Earth's atmosphere and reached its surface is mainly absorbed by this very surface. If all the energy that comes from the Sun to the Earth is taken as 100%, then 48% is absorbed by the surface. The remaining 4% (52% of what passes through the atmosphere minus 48%) is reflected from the Earth's surface.

When the atmosphere passes the sun's rays, it almost does not heat up. But the surface of the Earth, which they reach, heats up. As a result, the surface already becomes a source of heat for the atmosphere, and therefore the lower layers of the troposphere have a higher temperature than those lying above. This can be observed in the mountains, when the air temperature drops with height, and snow and ice may lie on the tops of the mountains, although there may be summer temperatures at the foot.

WHY DOES THE SUN SHINE AND WARM?

There is enough solar heat and light for all living beings on Earth, despite the fact that the Sun is at a distance of almost 150,000,000 km from us, and if suddenly our Sun went out, stopped shining and warming, it would become so cold that the whole water on Earth, even the air would freeze. People, animals, plants would die. Our planet would become cold and dead.

The temperature on the surface of the Sun is about 6 OOPS. At such a high temperature, iron and other metals not only melt, but turn into hot gases. Therefore, there are neither solid nor liquid substances on the Sun: there is only hot gas. The sun is a huge hot ball of gas. The temperature inside the Sun is even higher than on its surface. Near the center of the ball, it reaches 15 million degrees. Such a high temperature inside the Sun has existed for several billion years and will continue to exist for about the same. What happens inside the sun? Why doesn't this giant fire go out? Astronomers and physicists have been pondering the question for a long time: how is a very high temperature maintained inside the Sun for billions of years? Most scientists believe that inside the Sun chemical element hydrogen is converted into another chemical element helium. Particles of hydrogen combine into heavier particles, with this combination, energy is released in the form of light and heat, which is scattered by the Sun in outer space and comes to Earth to give life to all living things.
