The inside of the sun is divided into several layers, and the solar layer is divided into which thre

Photosphere, chromosphere, corona.

There is only one layer inside the sun, the inner core!

The temperature of the sun's inner core is 15 million degrees Celsius, where hydrogen-helium fusion reactions take place. Nuclear fusion reactions consume about five million tons of matter per second and convert them into energy that is released in the form of photons. It takes more than a million years for these photons to reach the surface of the sun from the center of the sun.

After the photon travels from the center of the sun, it passes through the radiation belt, losing energy in collisions with atomic particles along the way. It then passes through the convection zone, where the photon's energy is absorbed by the hot gas, which transfers energy to the surface in the convection current. By the time they reached the edge of the convection zone, the photons had cooled to 5,500 degrees Celsius.

The nuclear reaction layer, the radiation layer, the troposphere.

The solar atmosphere is photosphere, chromosphere, and corona from the inside to the outside. The sun is the most important energy of the earth**, which is related to the fate of the entire human race. The Sun is a gaseous planet, and thermonuclear reactions inside it continuously produce enormous amounts of energy, and the temperature difference between the interior and exterior causes massive gas convection movements.

The solar atmosphere is divided into photosphere, chromosphere, and corona from the inside to the outside. According to the relative intensity of solar activity, the sun can be divided into two categories: the quiet sun and the active sun. The Tranquility Sun is a theoretically assumed spherically symmetrical hot gas sphere whose properties vary only with radius and are uniform in either sphere, with the aim of studying the general structure and general properties of the Sun.

The sun is of the solar system. The central celestial body, which occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

<> the Sun's atmosphere is divided into three layers: the photosphere, the chromosphere, and the corona from the inside out.

Clause. 1. Photosphere: about 5,000 kilometers thick, the visible sunlight we see is almost all emitted by the photosphere, and there are rice grain-like air masses on the surface of the photosphere that do not change with time and are evenly distributed, which are in a violent undulating motion, and are hot air masses that rise from the troposphere to the photosphere, called rice grain organization;

Clause. 2. Chromosphere: from the surface of the photosphere to the height of 2000 kilometers is the chromosphere, which can only be observed during the total solar eclipse or with a chromosphere telescope.

Clause. 3. Coronal layer: Outside the chromosphere is the coronal layer, which has an extremely high temperature, extending several times or even dozens of times the radius of the sun

1. Corona. The layer temperature can reach 1 million degrees Celsius.

The solar corona refers to the outermost layer of the Sun's atmosphere (its interior is the chromosphere and the photosphere), which is more than a few million kilometers thick. Beyond the chromosphere is the coronal layer, which is extremely hot, with a temperature of 1 million degrees Celsius.

2. The temperature of the chromosphere is 4,600k tens of thousands of degrees from the inside to the outside.

The chromosphere is in the solar atmosphere.

However, there is an abnormal distribution of temperature inside. Within the chromosphere, which is about 2,000 kilometers thick, the temperature increases from 4,600 K at the top of the photosphere to tens of thousands of degrees at the top of the chromosphere, while some other physical parameters such as density, ionization.

etc.), and some physical processes have also changed dramatically. Therefore, the study of the physical condition of the chromosphere has attracted a lot of attention from solar physicists.

3. The temperature of the photosphere is 5500 degrees.

Although the ball of light is bright as a whole, the brightness of the parts of the limbs is very uneven. , the undisturbed photosphere is covered with rice grains, the total number is estimated to reach 4 million, and in the active area of the photosphere, there are sunspots.

Flares of light and occasionally flares of white light.

Their brightness, physical state and structure are very different, and the average undisturbed photosphere emits a radiation rate of Erg per square centimeter per second, from which the effective temperature of the photosphere can be calculated to be 5500 degrees.

The sun is fighting rocksAtmosphereFrom the inside to the outside, it is divided into photosphere, chromosphere and auspiciousCoronaLayer. The temperature of the solar atmosphere is at a minimum of about 4,500 degrees Celsius at the edge of the chromosphere above the photosphere 500 km.

Then, with the increase in altitude, the temperature in the transition zone increases rapidly, and at the bottom boundary of the coronal zone at an altitude of 10,000 km, the temperature has reached more than 10 degrees Celsius to the sixth power.

1. Photosphere.

The solar photosphere is the circle of the sun that we usually see, which is the lowest or innermost layer of the sun's atmosphere, with a thickness of 500 kilometers, and the average density is only a few hundred million times that of water, sunspots.

The activity takes place on this floor.

2. Chromosphere.

The layer of atmosphere immediately above the photosphere, about 8,000 kilometers thick, has a much lower density and pressure than the photosphere. The phenomenon of "Sun" occurs at this level.

3. Solar corona.

The corona is the outermost layer of the Sun's atmosphere. Its density is lower than that of the chromosphere, while its temperature is inversely proportional.

The chromosphere is as high as millions of degrees Celsius, and it extends from the chromosphere to several solar radii, and the corona also expands outward, causing cold ionized gas particles to flow out of the sun continuously, forming the solar wind.

The atmosphere of the sun.

The order from the inside to the outside is the light ball, the color ball, and the coronal attack.

The solar atmosphere is the outer layer of the sun, which is the photosphere, chromosphere and corona from the inside out. Ming Zen burns.

3. Solar corona.

The corona is the outermost layer of the Sun's atmosphere, with a lower density chromosphere, while its temperature is higher than the inverse chromosphere, which can reach millions of degrees Celsius.

It extends from the chromosphere to several solar radii. The solar wind is also formed by the outward expansion of the solar induced corona, which causes cold ionized gas particles to flow continuously outward from the sun.

1. The sun is mainly divided into internal structure and atmosphere from the inside to the outside, and the sun is a huge and hot gas planet. Knowing the distance between the sun and the earth, and then measuring the diameter of the angle of view of the sun's circle from the earth, we can find that the radius of the sun is 10,000 kilometers, which is 109 times the radius of the earth. From this, it can be calculated that the volume of the Sun is 1.3 million times that of the Earth.

2. According to Kepler's third law of planetary motion, astronomers can also calculate that the mass of the sun is 330,000 times that of the earth by using the mass of the earth and the radius and period of its orbit around the sun. And concentrates the mass of the solar system. However, even such a behemoth, in the vast universe, is just an ordinary star of medium mass.
