Atmosphere of Earth Layers and Its Functions – For us, the atmosphere is the most important part of the Earth. It’s because of the presence of the atmosphere that you can breathe. The air in the atmosphere is composed of different types of gases.
The gas making up the atmosphere are nitrogen (78 percent), oxygen (21 percent), argon (0.9 percent), and carbon dioxide (0.03 percent). The earth became a unique planet in the universe because there was oxygen that humans could use to breathe.
The atmosphere is not only useful for breathing. The atmosphere also protects the Earth from harmful Solar radiation. The atmosphere also protects the Earth when other dangerous objects in space fall. The atmosphere protects us from meteoroids falling from space.
Before it reached the surface of the Earth, the meteor had been burned because it was rubbing against the air in the atmosphere. In addition, the atmosphere keeps the temperature on Earth warm and comfortable to live in.
Atmosphere of Earth Layers
The layers of the Earth’s atmosphere are a blanket of gases that covers the planet. The atmosphere contains a wide variety of gases that living things need on earth.
The Atmosphere of Earth Layers become the place where the rain forms until it falls to the mainland. The atmosphere has several elements based on its temperature differences.
That part of the atmosphere becomes the layers that make up it. Here are some elements of the Earth’s atmospheric layer.
Troposphere
The troposphere is the lining of the alley closest to the earth’s surface. This layer has a distance of 14 kilometers from the earth’s surface. The troposphere has several contents, among which are Water planet layers, convection, tropopause.
Stratosphere
The second layer is the stratosphere layer. This layer is located at an altitude of 12 km-60 km. In the stratosphere layer, there is a sulfate material, which is what affects the occurrence of rain. In addition, the stratosphere is quite special, because there is an ozone layer. This ozone layer serves to block out sunlight, which, of course, if there is no ozone layer, the Earth will be very hot. Thank God there’s an ozone layer.
Mesosphere.
The third or most middle layer is the mesosphere. This layer is at an altitude of 60 km-80 km. You need to know that in the mesosphere layer the air temperature is increasingly unstable, every distance of 100 meters the air temperature will drop by 0.4 °C, the peak can reach -120°C.
Well, if there is a meteor falling with even hot temperatures, it will break into pieces when it enters this one layer. Well, the inhabitants of the earth, really protected.
Thermosphere
The thermosphere layer is a warm layer in the atmosphere. It is located at an altitude above 85 km from the earth’s surface.
In this layer, the temperature rises again with the altitude.
This happens because the air molecules that absorb heat, then heat up the environment.
In the thermosphere layer, the density is very low because the number of atoms and molecules is very small.
The presence of these particles actually has a significant effect because the absorption of a small amount of solar energy can raise the air temperature high.
In the thermosphere layer, the Aurora phenomenon occurs, which is formed due to the interaction of charged particles from the sun with a thin layer of air in the thermosphere.
Exosphere
It is called the exosphere because it is the outermost layer of the atmosphere, where the influence of gravity is so small that air collisions rarely occur. The height of this layer is between 500 km to 1,000 km. The gas grains in this layer gradually escape into outer space. This layer is also called exobase.
