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 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
Importance of carbon dioxide gas
We use carbon dioxide gas in making the soda water, We use it to make fire extinguishing equipment as carbon dioxide gas does not burn and does not help in burning, We can use it in the photosynthesis process, the green plants take carbon dioxide gas and give out oxygen gas.
|In the 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 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.
