Question

Argon is a greenhouse gas.
A) True
B) False

Answer 1

Hint: The gases responsible for promoting green house effect are green house gases which leads to major environmental problems like rising of temperature of earth.
- A gas is not a greenhouse gas if it is transparent to the wavelength of spectrum lying in the infrared region which does not lead to trapping of such radiations and hence no greenhouse effect.

Complete step by step solution:
- Argon is also abundant in atmosphere like oxygen and nitrogen.Argon makes up about percent of the Earth’s atmosphere .Argon is not a greenhouse gas because it allows the sun light radiations to pass through them which further doesn’t promote the rise in temperature of earth as the infrared radiations aren’t trapped in the blanket of gases of our atmosphere surrounding earth.on the other hand greenhouse.
- Gases contribute to atmospheric warming when they absorb infrared radiation emitted by the solar-warmed Earth and transfer their extra energy to the surrounding atmospheric gases.
- Examples of such gases are carbon dioxide ,sulphur dioxide which significantly promote green house effect which further leads to major problems like global warming. Greenhouses have large areas of glass that let in sunlight: like carbon dioxide, the glass blocks infrared light, warming the room.
So, the correct answer is “Option B”.

Note: 

Some gases enter the atmosphere from human activities like burning fossil fuels or even decomposition of organic matter which contribute to greenhouse effect.
- Even refrigerators and AC’S release CFCS (Chlorofluorocarbons ) which are responsible for greenhouse effects on a large scale.
