How thick is the atmosphere?

The atmosphere surrounding the Earth, the higher it goes, the more thin and thin the density, and gradually moves into space.
The entire atmosphere can be divided into several layers:
The air layer most closely related to us is from 10 to 12 km above the ground. It is the lowest layer of the atmosphere, called the troposphere.
The hot air from below always rises; the cold air above doesn’t stop sinking; they exchange fast and continuously. Water vapor in the troposphere is the most concentrated; dust is also much affected by the ground. The main meteorological phenomena, such as clouds, rain, ice, and snow, all arise in this layer. Above the troposphere until a height of 50 km is called the stratosphere.

The air in the stratosphere is much thinner compared to the troposphere. The amount of water vapor and dust there is very little, so there are very few meteorological phenomena. About 25 km from the ground is a concentrated area of ‚Äč‚Äčozone gas.

From the stratosphere up to 80 km, someone recently called the intermediate layer. On this floor, the temperature drops with height. From 80 km up to about 500 km, this floor space is called the thermal layer; this layer’s temperature is very high; the change of day and night is very large. Starting from 50 km up to 1000 km is called the ionosphere. In this ionosphere, sunlight (mainly ultraviolet rays) is radiated. The gas molecules are electrolytic into positive ions and free electrons. In which the area from the ground from 80 to 500 km, the ion density is relatively large. Beautiful auroras appear in this ionosphere.

500 km or more from the ground is called the outer atmosphere. It is the outermost layer of the atmosphere, the region of the atmosphere transitioning into space. Its outside has no distinct borders. Under normal conditions, the upper limit at this level is relatively low. The upper limit in the equatorial region deviates towards the Sun, with a 9-10 times the radius. Earth, in other words, has an altitude of about 65,000 km. There the air is extremely thin. As everyone knows, the sound is transmitted through the air. Out of the atmosphere, because the air is very thin, even though there is a firecracker in your ear, it’s hard to hear.

I used to look up at the sky when I was a child and wonder what's in those stars. Growing up, when I had the opportunity to contact the source of human knowledge, I had more knowledge about the universe, the natural world, and created laws. Being the founder of Wikiwap is where I can share my understanding of the world around me in a simple way that readers can access knowledge like a child. You and I are parts of the world; life will always be beautiful.
