Give an account of the composition of atmosphere also discuss the importance of components
Answers
The composition of air consists of three key components of air, namely Nitrogen (78%), Oxygen (21%), Argon (1%), Carbon dioxide (0.03%) and water vapor. Air also has some other gases but they are in very minute percentage.
Oxygen: The most important gas in the composition is oxygen. Oxygen is an important gas, both for humans as well as the atmosphere. It supports in breathing for living beings, but at the same time, oxygen is a combustible gas, which means, it can catch fire quickly.
Nitrogen: To balance out oxygen, there is Nitrogen. It is a non-combustible gas and occupies the highest percentage of air.
Argon: This gas is known to occur naturally in the environment and easily dissipates in a well-ventilated space. In itself, argon is an asphyxiant and inhalation of it can lead to dizziness and nausea in a person.
Carbon dioxide: Carbon dioxide is infused in the air due to respiration. Living beings inhale oxygen and exhale carbon dioxide.
Water vapor: When the water present in the water bodies evaporates due to heat, it rises up and mixes into the atmosphere.
Other Particles: Apart from the natural gases, air also contains things like smoke and dust.
