In which layer of the ozone layer do all kinds of weather changes occur? There seems to be an ionosphere. Explain the trouble in the outer layer.

The atmosphere is also called the atmosphere, and the earth is surrounded by this thick atmosphere. The main component of the atmosphere is nitrogen, accounting for 78. 1%. Oxygen accounts for 20.9%; Hydrogen accounts for 0.93%; There are also small amounts of carbon dioxide, helium, neon, krypton, xenon and water vapor. The air density of the atmosphere decreases with the increase of altitude. The higher it is, the thinner the air is. The thickness of the atmosphere is about 1000 km, but there is no obvious boundary. The whole atmosphere shows different characteristics with different heights, including troposphere, stratosphere, mesosphere, warm layer and mesosphere, above which is interstellar space.

The troposphere is at the bottom of the atmosphere, close to the earth's surface, and its thickness is about 10 to 20 kilometers. The atmosphere in the troposphere is greatly influenced by the earth. Clouds, fog, rain and other phenomena all occur in this layer, and almost all water vapor exists in this layer. The temperature of this layer decreases with the elevation, and the temperature drops by 5 ~ 6℃ per1000m. It is also on this floor. This layer of air is called troposphere because of its obvious convection. Above the troposphere is the stratosphere, about 20 to 50 kilometers from the earth's surface. The stratosphere is called stratosphere because the air is relatively stable and the atmosphere flows smoothly. There is little water vapor and dust in the stratosphere. Below 30 kilometers is the stratosphere, and the temperature is about -55℃. Above the stratosphere is the mesosphere, about 50 to 85 kilometers from the earth's surface. The air here is already very thin, and the outstanding characteristics are that the temperature drops rapidly against the height increase and the vertical convection of the air is strong. Above the middle layer is the warm layer, which is about 100 to 800 kilometers away from the earth's surface. The most prominent feature of the warm layer is that when the sun shines, the ultraviolet rays in the sun are absorbed by the oxygen atoms in the layer, so the temperature rises, so it is called the warm layer. The escape layer is above the warm layer and consists of charged particles.

In addition, there are two special layers, namely the ozone layer and the ionosphere. The ozone layer is 20 to 30 kilometers from the ground, actually between the troposphere and the stratosphere. This layer is mainly due to the photochemical action of ultraviolet rays of sunlight on oxygen molecules, which makes oxygen molecules become ozone. The ionosphere is very thick, about 80 kilometers from the earth's surface. Ionosphere is a kind of gas in the sky, which is irradiated by ultraviolet rays of sunlight. Ionization into charged positive ions, negative ions and some free electrons. The ionosphere has a great influence on electromagnetic waves. We can realize the long-distance communication of electromagnetic waves by using the characteristic that the short wave of electromagnetic waves can be reflected back to the ground by the ionosphere.

Under the action of the earth's gravity, a large number of gases gather around the earth, forming thousands of kilometers of atmosphere. The gas density becomes thinner and thinner with the increase of height from the ground. Sounding rockets still find a thin atmosphere at an altitude of 3000 kilometers. Some people think that the upper boundary of the atmosphere may extend to about 6400 kilometers above the ground. According to scientists' estimation, the atmospheric quality is about 6 trillion tons, accounting for almost one millionth of the total mass of the earth. Include nitrogen 78%, oxygen 2 1%, argon 0.93%, carbon dioxide 0.03%, neon 0.00 18%, and water vapor and dust.
