What the earth gives to the sun, and what and what is on the earth is sent by the sun

The earth gives the sun dignity and glory, and makes it realize how valuable its existence is!

The earth gave the sun a reason to live.

Although it has not yet been discovered, there will definitely be.

For example, in a few hundred years, the sun may no longer be hot, and the earth may be able to restore sunlight to the sun.

The earth is the child of the sun, and the sun takes care of him like a mother, giving him light and heat, so that there is life on the earth.

The sun gives the earth light and heat.

Gave the Earth a rotating orbit.

Opposite. The Earth also maintains the position of the Sun in the universe.

Stabilize other celestial bodies in the solar system.

The earth is a star of the sun and a reference of the sun.

The sun gives the earth the opportunity to give birth to life.

According to the principle of gravitation, when attracting each other, the sun attracts the earth, and the earth attracts the sun. That is, if there was no Earth, then the gravitational equilibrium system of the solar system would be broken, and the solar system would not exist. The sun will also die due to the disappearance of the earth.

The light and warmth on the earth are sent by the sun.

If there was no sun, the earth would be dark and cold everywhere. There is no wind, snow, rain, dew, no grass, no wood, no birds, no beasts, and naturally there will be no people. It can be said that the earth is created by the sun, all living things are inseparable from sunlight, life, humans, plants, animals, without the sun there would be no earth.

The Sun is the only star in the solar system; It is the central celestial body of the solar system, the star of the Milky Way, and the earth gets its light and heat from the sun, so that everything in the world is no longer in a state of cooling and boundless darkness.

Solar activity

The sun looks calm, but in fact there is vigorous activity happening all the time. From the inside to the outside, the sun is divided into the solar nuclear reaction zone, the solar troposphere, and the solar atmosphere. One in 2.2 billion of this energy radiates to the Earth, becoming the main source of light and heat on Earth.

Active phenomena on the surface of the Sun and in the atmosphere, such as sunspots, flares and coronal mass eruptions (solar eruptions), can greatly enhance the solar wind, causing many geophysical phenomena such as increased auroras, atmospheric ionosphere and geomagnetic changes.

The enhancement of solar activity and solar wind will also seriously interfere with the normal operation of radio communications and space equipment on the earth, cause damage to the sophisticated electronic instruments on the satellite, cause chaos in the ground communication network and power control network, and may even pose a threat to the lives of astronauts in the space shuttle and space station. Therefore, it is increasingly important to monitor solar activity and the intensity of the solar wind and to make "space weather" forecasts in a timely manner.

Question 1: What star is the sun, what star is the earth, what star is the moon, what star is the earth The sun is a star, and the celestial body that can rely on thermonuclear fusion to shine and heat itself is called a star.

The Earth is defined as a planet of the sun, and a planet is a near-spherical object that orbits a star and is relatively massive enough to clear small bodies near its orbit.

The Moon is defined as a satellite of the Earth, and a satellite is a natural celestial body that orbits a planet and orbits periodically in a closed orbit.

Definition Question 2: What is the Earth and what is the Moon The Earth is the planet of the Sun, and the Moon is the satellite of the Earth.

Question 3: What is the relationship between the sun, the earth, and the moon The sun is the center of the solar system, the earth is a planet in the solar system, and the moon is a natural satellite of the earth.

In the Earth-Moon planetary system, the Moon revolves around the Earth, and the Earth rotates constantly, creating a difference between day and night.

A solar or lunar eclipse occurs when the three line up in a straight line:

A solar eclipse occurs when the moon blocks sunlight from reaching the Earth in the middle;

A lunar eclipse occurs when the Earth blocks the sunlight from shining towards the moon in the middle.

Question 4: Which came first, the sun or the earth, the earth and the sun were formed first, it is obvious that there was the sun first, and the remnants of the primordial sun** formed the other planets in the solar system. The actual observed age of the Sun is about 5 billion years, and the Earth is about 4.6 billion years.

The sun has a close relationship with human beings, because there is sunshine, there is sunshine, there is sunshine, there is life, can survive, human beings can not live without the sun!

The sun and the earth are both celestial bodies in the universe, and they both have the characteristics of celestial bodies, and they are very magical.

The radius of the Sun is about 702,020 km, and the radius of the Earth is about 6,371 km. The Sun is about 1.3 million times the size of the Earth and has a radius of about 109 times that of the Earth. The Earth is about 100 million kilometers away from the Sun.

On January 7, the Earth is closest to the Sun, about 100 million kilometers away. On July 7, the Earth is farthest from the Sun, about 100 million kilometers away. By comparison, you will find that if the sun is a basketball, the earth is only the size of a sesame seed, and it is about 120 meters away from the basketball.

The sun is a glowing sphere with a surface temperature of about 6,000 degrees Celsius and a core temperature of about 100 million degrees Celsius. Even if the sun is so hot, it can't make the cosmic vacuum space from the earth to the sun warm, and it is only about -275 degrees Celsius, which is close to absolute zero. The size of the sun is not very large.

In the universe, Sirius is equivalent to 7 suns, North River III is equivalent to 100 suns, Arcturus is equivalent to 1000 suns, Aldebaran is equivalent to 9000 suns, and UY is equivalent to 100 million suns, with a diameter of 2.3 billion kilometers, and if it is placed in the center of the solar system, its surface can engulf the orbit of Jupiter, close to the orbit of Saturn. It can be seen how small our earth is.

The Sun and the Earth have lived for about 4.6 billion years. Every billion years, the sun's rays increase by 10. The life span of the sun is about 10 billion years.

About 5 billion years later, the Sun dies and expands into a red giant. After 6 billion years, Mercury was engulfed; Venus will be engulfed after 7 billion years, and the lifeless Earth will be engulfed after 7.9 billion years. Eight billion years later, the Sun will be left with only the shell of a white dwarf.

But before the earth was swallowed up, the surface temperature of the earth was at least 2,000 degrees, and we humans could not survive that time.

Our planet receives only a few hundred million parts of the sun's radiation, and the atmosphere reflects sunlight. But this sunlight is enough for us. If there were no atmosphere, the Earth would be more than 500 meters above the surface like Venus.

If all the oceans on Earth were brought together, only a ball with a diameter of 1,500 kilometers would form, and its volume would be only one-eightieth the size of the Earth. In hundreds of millions of years, the earth's ice will melt, which will make the sea level **70 meters, and will also cause serious desalination.

Therefore, we should cherish the only resources we have now, and protect every field, every inch of soil, and every river around us.
