The temperature of the atmosphere, the thickness of the atmosphere is about how many kilometers

What's all that stuff going on? Look at mine.

The top of the troposphere is about -90, and the temperature of the stratosphere up is also slowly decreasing, to the lowest -110, and then because the atmosphere is too thin, the air molecules are excited by sunlight, producing high-speed movements, which make the temperature rise, usually up to 3000 degrees, but because there are few molecules here, the usual concept of perceptual temperature is no longer applicable.

The shuttle was designed to withstand a maximum temperature of 1650 degrees Celsius, and the actual temperature was 1350-1400 degrees.

There is a thermosphere with a temperature of 1000 in the atmosphere, why didn't the spacecraft burn out when it flew here?

The thickness of the atmosphere is about 1000 kilometers or more.

The atmosphere is a meteorological term, which is a layer of mixed gas that surrounds the earth due to gravity, and is the outermost gasosphere of the earth, surrounding the ocean and land, and the thickness of the atmosphere is about 1000 kilometers or more, but there is no clear boundary. The entire atmosphere exhibits different characteristics with different altitudes, and is divided into troposphere, stratosphere, mesosphere, warm layer and fugitive layer, and above it is interstellar space.

The thickness of the atmosphere is more than 1,000 km.

The atmosphere, like an onion, is layered on top of each other. The density of air in the atmosphere decreases with altitude, and the higher the air, the thinner it is. The thickness of the atmosphere is about 1,000 kilometers or more, but there are no clear boundaries.

The entire atmosphere exhibits different characteristics with different altitudes, and is divided into troposphere, stratosphere, mesosphere, warm layer and fugitive layer, and then interstellar space.

The division of the Earth's atmosphere.

1. Troposphere.

The troposphere is the lowest layer close to the ground and is the most active layer of the atmosphere and most closely related to humans. Our common weather phenomena such as wind, rain, thunder and lightning occur at this level. The temperature in this layer gradually decreases with height.

2. Stratosphere.

The stratosphere is mainly advection motion, which is conducive to high-altitude flight, and aircraft generally fly in this layer; In addition, the ozone layer in the stratosphere absorbs the sun's ultraviolet rays, protecting life on Earth from the sun's harmful radiation. The temperature in this layer increases rapidly with height.

3. The middle layer.

The mesosphere, also known as the mesosphere, refers to the atmosphere from the top of the stratosphere to 85 km. Due to the low ozone content in this layer, and at the same time, most of the solar shortwave radiation that can be directly absorbed by nitrogen and oxygen has been absorbed by the upper atmosphere, so the vertical decline rate of temperature is very large, and the convective movement is strong.

4. Warm layer. From 80km to about 500km is called the thermosphere. The temperature of this layer increases rapidly with the increase in height, the temperature in the layer is very high, the diurnal variation is great, and a small amount of moisture is still present in the lower part of the thermosphere, so there are occasional silvery-white and slightly cyan noctilucent clouds.

5. A fugitive layer.

The fugitive layer is also called the outer layer, the escape layer, and the atmosphere above the warm layer is also the outermost layer of the earth's atmosphere. Most of the molecules in this layer of air are ionized under the action of the sun's ultraviolet rays and cosmic rays; So that the content of protons and helium nuclei greatly exceeds the content of neutral hydrogen atoms. The escape layer is extremely thin and has a density almost the same as that of space, so it is often referred to as the outer atmosphere.

Atmospheric temperature refers to the temperature change in air temperature in the atmosphere that changes with increasing altitude. Atmospheric temperature is a very important meteorological parameter because it has a direct impact on air currents, cloud formation, and precipitation in the atmosphere, as well as ionospheric changes in the atmosphere.

The temperature of the atmosphere varies with altitude. In general, the atmosphere at initial sea surface altitude will show an unstable temperature profile. Among them, from sea level to an altitude of about 11 kilometers in the atmosphere, the temperature decreases as the altitude rises.

This is due to the fact that the heat exchange between the atmosphere and the ground is achieved through thermal convection. Once the ground is heated, the air begins to rise, then cools and forms clouds, which eventually circulate the water back to the ground. However, in the atmosphere from an altitude of about 11 km to 50 km, the temperature rises with altitude, especially in the stratosphere.

This is because the heat of this layer** is mainly cosmic radiation, not the ground. In this layer, the gas becomes very thin and therefore has a much less effect on the absorption and release of heat. At altitudes above 50 km, the temperature begins to drop again, gradually dropping to absolute zero as the altitude increases.

Changes in atmospheric temperature have an important impact on weather forecasting and aviation flights. For weather forecasting, understanding changes in atmospheric temperature can provide more accurate forecasting data. For aviation flights, understanding atmospheric temperature changes can help locate aircraft and plan paths, while higher temperatures at high altitudes can also affect flight altitude selection and the amount of greenhouse gases emitted.

In general, atmospheric temperature is a very important meteorological parameter, and in extended studies, we can use a deep understanding of atmospheric temperature changes to better understand weather changes,** and plan measures to deal with weather changes. <>
