Arrange the following gases in descending order in terms of percentage in dry air of the lower atmosphere. (A) Carbon dioxide (B) Argon (C) Nitrogen (D) Oxygen Choose the correct answer from the options given below :
Atmospheric Gas Concentrations
The question requires arranging the gases Nitrogen (C), Oxygen (D), Carbon Dioxide (A), and Argon (B) in descending order based on their typical percentage in the Earth's dry lower atmosphere.
Gas Ranking Order
Based on the common composition of dry air, the gases are ranked by abundance. The order, corresponding to the correct answer choice, is as follows:
- Nitrogen (C)
- Oxygen (D)
- Carbon Dioxide (A)
- Argon (B)
This arrangement reflects the descending order of percentage: Nitrogen is the most abundant, followed by Oxygen, then Carbon Dioxide, and finally Argon, according to the sequence provided in the correct option. The resulting order of labels is (C), (D), (A), (B).
