The trace gases gases such as carbon dioxide, water vapor, ozone, and methane, as well as the manmade chlorofluorocarbons (CFC's), are all also categorized as "greenhouse gases." This is because each one of them has the ability to affect Earth's energy balance and change the temperature at the surface and in the air
Importance of carbon dioxide gas: Carbon dioxide gas shows greenhouse effect and maintains the atmospheric temperature suitable for life on earth. It keeps the air hot.
Importance of ozone layer: Ozone layer in the atmosphere absorbs the harmful radiations.
Importance of Methane gas: It is released into the air from landfills, livestock and their manure, and from oil and gas wells. It is also created when organic material decomposes. It is a heat-trapping greenhouse gas.
Importance of Argon: Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
