The components of the Earth’s atmosphere and the importance of them
Do you know what is the Earth’s atmosphere ? The Earth’s atmosphere is composed of a mixture of the different gases that make the life on the Earth possible .
The components of the atmosphere
What is the importance of the oxygen gas
Oxygen gas is very important and necessary for the respiration process , and burning of the fuel , Oxygen gas helps the divers in the respiration process under the water surface , We use oxygen gas with acetylene in cutting and welding of the metals .
Carbon dioxide gas
The importance of the carbon dioxide gas
We use carbon dioxide gas in making the soda water , We use it to make fire extinguishing equipments as carbon dioxide gas does not burn and does not help in burning , We can use it in photosynthesis process , the green plants take carbon dioxide gas and give out oxygen gas .
|In photosynthesis process , The plants take carbon dioxide gas and release oxygen gas to make their own food .|
It is the most abundant gas in the air , It is 78 % of the volume of the atmosphere .
The importance of nitrogen gas
In the combustion process , Nitrogen gas reduces the effect of oxygen gas , We use it in the industry of the ammonia and some nitrogenous fertilizers .
The water vapour
It is found in a small ratio in the atmosphere , The humidity increases in the coastal regions , It depends on the amount of the water vapour that represents in the air .
