Question

Increase in which of the following gases cause global warming?

• A. Carbon dioxide
• B. Oxygen
• C. Nitrogen
• D. Argon

Answer 1

The correct option is A

Carbon dioxide

Explantion for the correct option:

Option (A):Carbon dioxide

• Greenhouse gases like carbon dioxide, methane, and ozone absorb the infrared radiation in the wavelength range emitted by Earth and cause heating of the atmosphere of the earth which results in the greenhouse effect and also global warming.
• Carbon dioxide is considered the main source of greenhouse gas and it is responsible for Global-Warming.
• A layer of carbon dioxide that is present in the atmosphere traps the infrared radiation coming from the earth's surface and then it eventually heats the earth's atmosphere which results in global warming.

Explantion for the incorrect option:

Option (B): Oxygen

• Oxygen gas is not considered a greenhouse gas responsible for global warming.
• Hence, the option represents an incorrect statement.

Option (C): Nitrogen

• An increase in the nitrogen gas in the atmosphere does not cause global warming.
• Thus the given option doesn't coincide with the correct statement.

Option (D):Argon

• Argon gas does not count as a greenhouse gas and hence doesn't result in global warming.
• Hence, the given option does not correspond to the correct concept.

Therefore, option (A) is the correct answer. An increase in Carbon dioxide gas cause global warming.
