The growth and development of living things are inseparable from the sun, how is the sun born?

It is formed by interstellar clouds, and is also affected by gravity, which gradually expands and expands, and the temperature becomes higher and higher, and then the sun is produced.

Many scientists speculate that the sun is formed by the big **, and there is no careful study of the reasons for the formation of the sun, and there is no theory that can be proven.

It may have been born because of changes in the universe, or it may have existed since the universe was first born.

After the singularity**, the matter in the universe slowly gathers, and then the sun is formed.

a. Water cannot be directly provided by the sun

b. Solar radiation energy maintains the surface temperature and is the main driving force for water and atmospheric movement and life activities on the earth

c. Only 1/2.2 billion of solar radiation reaches the earth, providing a steady stream of energy for the earth**, which is the main energy used in our daily life and production

People with positive energy are like having the sun, with the light that illuminates and nourishes all things in the world.

Xiaobai's promotion.

In this world, there are positive and negative energies that maintain the balance of this world.

Positive energy is like the sun, shining brightly, allowing people to see light and hope.

Negative energy is like a dark cloud in the sky, where the dark cloud passes obscures the sky and the sun, the darkness is biased, and then it rains again and again, and it is a bleak wind and bitter rain.

We advocate positive energy and people with positive energy, bringing people happiness and making people move forward.

People with positive energy have a lot of things to do, which can keep them busy and ignore the hardships that life brings.

People with positive energy can reverse temporary losses and foresee the future of light. Although the process was difficult, the result was happy and sweet.

Lin Huiyin, China's first talented woman, did not waste her time complaining about all the sufferings of time, but applied her time and experience to study and create.

As a woman, Lin Huiyin's radiant light and role model for women have inspired countless women to be more comfortable and beautiful.

In the era of the patriarchal world, Lin Huiyin not only had his own career with knowledge and cultivation, but also had several romantic relationships and a sincere marriage.

A person with positive energy can do a lot of things, because he doesn't have time to be depressed and complain, so there are many things he can do.

People with positive energy can spread positive energy, use positive energy to influence others, and make the whole world feel warm.

Lifen is a person with positive energy, during the college entrance examination, she was very diligent and hardworking, due to overwork, Lifen actually fell ill three days before the college entrance examination.

When everyone thinks that Lifen is sick, they will put down their studies and go home to rest and recuperate. With the support of positive energy, Lifen did not go home to rest, but continued to review while sick, went to the hospital in the morning to hang the needle, and continued to review in the afternoon.

On the day of the college entrance examination, Lifen was still in a fever, and everyone thought that Lifen would definitely fail the college entrance examination this time, but how do you know, but Lifen played extraordinarily, and her score turned out to be a key university.

With a spirit of not admitting defeat, Lifen became the first student in the village to be admitted to a key university, and also became the pride of the whole village.

After graduating from college four years later, Lifen also relied on this positive energy to get ahead, returned to her hometown to teach in a key middle school, and became a teacher who respects others. In the face of batches of students, he sowed his sunshine and optimism, and used positive energy to influence the future of the motherland from generation to generation.

People with positive energy can live their own wonderful life no matter what kind of life they have.

It cannot be understood that the so-called growth of all things depends on the sun, which is described from the process of energy transfer, and the energy of the food required for the growth of animals and plants originally originated from solar energy, and was absorbed and transformed into organic energy in living organisms through green plants.

The environment refers to everything around the area where the organism lives, and all organisms (such as surrounding animals, plants and their microorganisms) and inorganic environment (such as water, soil, sunlight, etc.) that directly or indirectly interact with this organism.

That's right. Organisms are highly dependent on their environment, but in some special cases, organisms can also change certain aspects of themselves to adapt to the environment. And humans are trying to transform the environment.

Yes, sunlight is also an important living condition for the survival of living things.

First of all, I would like to talk about my understanding of the sun: first, I don't think it is a gas-coded friendly sphere, because under the high pressure of its interior, it is impossible for matter to exist in gaseous form, and I think it should be a celestial body that combines gas, solid, and liquid. Second, the energy it has does not come entirely from nuclear fusion, but also from radiation from internal heat sources.

This led to the idea of the formation of the sun: in the ancient space of the solar system, a primordial sun rotated. One day in a certain year and month, an alien visitor with a similar mass to the sun collided with the sun, and the jade died.

But it is not a complete **, but the impact of the components of the multiple, so, the formation of the same level of the nine planets, due to the size of the problem, the nine planets one by one cooled down, each formed its own small world, but the sun in the center, still exudes primitive energy.
