Weather of Arabia - The atmosphere is a group of gases that surround the Earth and extend into space. It is of great importance in protecting our planet and maintaining its thermal balance. It consists of several layers, each of which has several characteristics that distinguish it. This atmosphere surrounding us must be preserved and the harmful pollutants that affect it must be reduced. On him and on human life.
1- Protecting the Earth from harmful radiation such as ultraviolet rays
2- Maintaining moderate temperatures on the Earth’s surface
3- Responsible for the presence of fresh water on the surface of the Earth
4- Air is considered an important medium for transmitting sound waves because sounds do not travel in a vacuum
1- Nitrogen and oxygen 99%
2- Water vapor, carbon dioxide, ozone, etc. at a rate of 1%.
3- Impurities such as dust, salt particles, and smoke.
1- The lower layer of the atmosphere in which we live
2- Its height ranges between 8 km above the poles and 18 km above the equator
3- The temperature decreases with altitude by 6.5°C/km
4- It contains most of the water vapor in the atmosphere
5- The layer in which various weather phenomena occur
6- The end of the layer is called the tropopause
1- It extends from the tropopause to a height of 50 km above the Earth’s surface
2- The temperature increases with altitude
3- There is no water vapor in it
4- Ozone gas spreads there
5- Free from weather phenomena
6- Airplanes fly there and weather balloons are sent to them
7- The end of the layer is called the stratopoise
1- It extends from the stratosphere to a height of 80 km above the Earth’s surface
2- The temperature decreases with height
3- There is no water vapor in it.
4- No weather phenomena occur there.
5- Meteorites and meteors burn with it
6- The end of the mesopoise layer.
1- It extends from the mesopoise to the end of the atmosphere
2- The temperature increases with height, as a result of atomic oxygen absorbing ultraviolet rays
3- Ions spread throughout it, especially oxygen and nitrogen ions
4- Satellites orbit in it
The atmosphere surrounding us is a duty for all of us to preserve, by individuals and countries, by reducing pollutants and harmful emissions from factories, vehicles, forest fires, etc. We must also move toward using renewable, clean, and environmentally friendly energy, in addition to paying attention to planting trees for their role in absorbing harmful carbon dioxide gas. During these duties, the effects of climate change and global warming will be reduced and the quality of the air we breathe will be improved, thus preserving our planet and protecting humans.
