The question asks which gas is present in the minimum quantity in the Earth's atmosphere among the given options: Oxygen, Nitrogen, Carbon Dioxide, and Argon. Let's analyze the composition of the Earth's atmosphere to find the correct answer.
- Nitrogen (N2): Nitrogen is the most abundant gas in the Earth's atmosphere, comprising approximately 78% of the atmosphere by volume.
- Oxygen (O2): Oxygen is the second most abundant gas in the atmosphere, accounting for around 21% by volume.
- Argon (Ar): Argon is the third most abundant gas, making up about 0.93% of the atmosphere.
- Carbon Dioxide (CO2): Carbon dioxide is present in the atmosphere in much smaller quantities, approximately 0.04% by volume.
From the above analysis, it is clear that Carbon Dioxide constitutes the smallest percentage of these gases in the atmosphere.
Conclusion: The gas that is present in the minimum quantity in the Earth's atmosphere from the given options is Carbon Dioxide.
