What are the functions of the sun? What is the role of the sun?

Personally, I don't think it's really useful. Anyway, it's the sun. You can customize your avatar later. You can also create your own group...

1. The sun is the origin of human life; The origin of life requires energy, and life also needs energy to sustain and continue. Certain temperature conditions are also necessary for the survival and continuation of organisms, and at a minimum, water must remain in a liquid state. The sun brings us warmth and light, providing us with the necessary energy.

Sunlight can give people heat, improve blood circulation, promote the normal secretion of sweat and sebum, sunlight can kill bacteria, so that the surface of the human body maintains a normal bacterial flora. Photosynthetic organisms are the basis of the food chain. The Earth's energy is directly or indirectly supplied by sunlight.

2. Many geological and meteorological disasters on the earth are related to solar activity. Such as solar wind, sunspots, flares, etc.

3. Nowadays, through scientific and technological equipment, people have expanded the direct or indirect use of solar energy, the simplest is solar water heaters, and then solar power generation, using solar energy to drive vehicles.

The sun has many functions, the sun can use the front comma to generate electricity, the sun guarantees the formation of natural water, the normal circulation of gas, without the sun there will be no clever permeability temperature, human animals and plants will perish, without the sun the earth and other planets in the solar system will have no light, without the sun, the solar system will be meaningless.

1. Sunlight shining on our ** will dilate the subcutaneous blood vessels, increase blood flow, increase the excretion and resistance of toxic substances, increase the secretion of saliva and gastric juice, strengthen gastrointestinal peristalsis, and promote appetite and digestion.

2. **It can also produce vitamin D from some chemicals, such as ergosol and cholesterol, under the exposure of sunlight. These vitamins, calcium and phosphorus, which are important components of our bones, can lead to hypochondriasis.

3. Sunlight is more important for children, because they are growing and developing rapidly, and the development of Huikuan sells bones is an important role in supporting the whole body.

The role of the sun: The sun is vital to humans. The circulation of the earth's atmosphere, the rotation of day and night and the seasons, and the changes in the earth's cold and warm are all the results of the sun's action.

For astronomers, the Sun is the only star that can observe surface details. The role of the sun:1

It will not produce exhaust gas, and can use solar energy, solar cars, etc., which can save electricity and water and protect the environment; 2.The sun gives us light and heat; 3.Sunlight shining on ** will dilate the subcutaneous blood vessels, increase blood flow, increase the excretion and resistance of toxic substances, increase the secretion of saliva and gastric juice, strengthen gastrointestinal peristalsis, and promote appetite and digestion; 4.

on Earth. Energy is directly or indirectly supplied by sunlight and becomes the food chain; 5.Ultraviolet rays from sunlight can kill germs.

1. As the central celestial body of the solar system, the eight planets in the solar system and many other stars revolve around the sun;

2. The interior of the sun is composed of hot plasma and magnetic field, which provides light and heat for space;

3. The sun can provide light energy to plants on the earth for photosynthesis;

4. The solar energy produced by the sun can generate electricity.

The role of the sun:

1. Bring us light and heat.

2. It will not produce exhaust gas, and can be ...... with solar energy, solar cars, and solar watchesThese can save electricity, water, and the environment.

3. Sunlight shining on the ** will dilate the subcutaneous blood vessels, increase the blood flow in the hall, increase the excretion and resistance of toxic substances, and increase the secretion of saliva and stomach liquid, strengthen gastrointestinal peristalsis, and promote appetite and digestion.
