Which of the following is not a primary contributor to the greenhouse effect?
carbon dioxide
carbon monoxide
chlorofluorocarbons
methane gas
Answers
Chlorofluorocarbons are not a 'primary contributor' to the 'greenhouse effect'.
Explanation:
'Greenhouse effect' is a process by which the heat energy from the 'sun' is trapped inside the earth’s atmosphere. It is responsible for all the human and natural activity. It helps earth to reach a minimum temperature.
Major greenhouse gases are 'water vapor', 'carbon dioxide', 'methane' and 'ozone'. Today burning of fossil fuels, combustion in cars, burning of forests has resulted in increase in the level of greenhouse gases. That is the reason for global warming.
Carbon dioxide is not a primary contributor to the greenhouse effect.
Explanation:
Given options are as follows
1.Carbon dioxide- It is not primary contributor for the green house effect. It is produced during the burning of coal, oil, natural gas, and other fossil carbon-rich fuels. It is not a green house gas but its contribution to climate change is maximum.
2.Carbon monoxide-This gas contributes directly to the green house effect. It is indirectly the powerful green house gas. It react to produce new green house gases.
3.Chlorofluorocarbons - It is better known as CFC. They are made of chlorine, fluorine and carbon compounds. In the destructive reaction the ozone particles the earth's protective layer against UV radiation. They are harmful when found in air.
4.Methane gas - This gas is formed by the destruction of plant matter and is generally released from landfills and rice paddy fields.
Although methane gas are less emitted than carbon dioxide emission.
