The more detailed and urgent the influence of the sun on the earth's environment, the more online the better.

(1) The mass and size of the sun The radius of the sun is about 700,000 kilometers, which is/kloc-0.09 times that of radius of the earth and/kloc-0.3 million times that of radius of the earth. The mass of the sun is 2× 1027 tons.

(2) The external structure of the sun is the thin gas outside the sun, which is called the solar atmosphere. According to their physical properties, they can be divided into photosphere, chromosphere and corona. The dazzling and rough surface of the sun that people see every day is called the photosphere. The above-mentioned sun size refers to the photosphere. The sun's atmosphere above the photosphere is called chromosphere. Chromosphere is usually invisible due to strong light from the photosphere. Only when the photosphere is covered by the moon during the total solar eclipse can this layer of gas be observed. It is rosy, so it is called chromosphere. The corona is the very thin outermost layer of the solar atmosphere above chromosphere.

(3) Solar temperature and photothermal source The sun is almost the only source of light and heat for the whole solar system. The sun radiates a huge flow of light energy in the form of electromagnetic waves, which is called solar radiation. It emits 9.4× 1025 calories per second. Most of the energy emitted by the sun goes into space, and only1/22 billion of the total energy reaches the earth.

Sunlight is basically emitted from the photosphere. The surface temperature of the photosphere is about 5500℃, and the temperature of the sun center is not lower than 15 million℃. How does the sun's light and heat come from? The research shows that the solar photothermal energy comes from the thermonuclear reaction in the sun, and the energy released by the transformation of 1g hydrogen nucleus into helium nucleus is about equal to the energy released by burning 15t coal.

Second, the influence of the sun on the earth.

The sun is not calm, it keeps moving. There are storms with hundreds of thousands of kilometers per hour on the sun, latosolic red flames with millions of kilometers, and huge explosions with tens of millions of times the power of hydrogen bombs. All these activities are collectively called solar activities, which have an important impact on the earth. The sun gives light and heat to the earth, and constantly transmits energy to the earth to maintain life activities on the earth.

(1) Sunspots and Flares When the sun is active, black spots of different sizes can be observed by the naked eye (in the morning). This is a sunspot, which is the most important aspect of solar activity. In some areas of chromosphere, explosions sometimes occur suddenly, and especially bright spots can be found through instrument observation. These bright spots are called flares. It is located in the sunspot group and its vicinity.

The appearance of sunspots and flares shows that solar activity is strengthened, and a large number of radiation particles are ejected, which interferes with the atmospheric circulation on the earth and makes the global weather and climate abnormal. For example, in the year when sunspots appear in large numbers, there may be abnormal drought in some areas of the earth, catastrophic floods in some areas, warm winters in some areas and so on.

(2) Magnetic Storm and Aurora Phenomenon When the solar activity is strong, a large number of charged fine substances ejected by the sun are called particle radiation. When the particle flow arrives near the earth, it disturbs the earth's magnetic field with its own magnetic field, making the compass beat violently and continuously. This is the phenomenon of magnetic storm. A large number of particle streams are also shot into space at an extremely fast speed. When some of them enter the high altitude near the earth, they collide violently with the thin atmosphere in the high altitude of the earth and emit light, showing a colorful scene called aurora. Aurora phenomenon is generally only visible above the earth's magnetic poles and high latitudes.

(3) The ionosphere has a strong disturbance to the sun, and the ultraviolet rays and X-rays of the sun are also enhanced, which can interfere with the ionosphere in the upper atmosphere of the earth, and at the same time absorb the radio short waves emitted by the ground, so that the radio communication on the earth is blocked or even interrupted. This phenomenon is called ionospheric disturbance.

The above answer is silly. If the answer is the influence of human beings on the earth, I think it is almost the same!

I. Overview of the Sun

The sun is the main source of life and energy on the earth. Light and heat are the most common. They bring all kinds of gases, life, environment and seasons to the earth. ...

Speaking of influence, when sunspots and flares on the sun increase, strong radio will disturb the ionosphere above the earth, affect short-wave radio communication on the ground, and even cause short-term interruption. High-energy protons released during large flares are extremely destructive to space activities. High-energy protons reach the elbow near the earth, especially in polar regions without radiation belt protection, which will affect polar flight; If it is a satellite, it will destroy the instruments and equipment on the satellite; Under the bombardment of high-energy protons, the performance of solar electricity will be seriously degraded and even unable to work; If astronauts work outside the spaceship, their lives will be threatened.

The charged particle stream thrown from the sun's atmosphere can disturb the earth's magnetic field and produce the phenomenon of "magnetic storm", which makes the magnetic needle vibrate violently and can't indicate the direction correctly.

As for the simple influence, from the comparison between the equator and the polar regions, we can see that their distance from the sun is the largest, and the difference in influence is also the biggest!
