If we arrange different gases in decreasing order of their percentage...
The atmosphere is a thin layer of gases which stays above the earth due to the force of gravitation. Its air is colourless, odourless and tasteless.

Nitrogen and oxygen are two major gases of the atmosphere. Carbon dioxide (CO2), Helium, Ozone, Argon and hydrogen are found in lesser quantities. Apart from these gases, tiny dust particles are also present in the air.
The atmospheric composition of gases are as follow
| Permanent Gases of the Atmosphere | |
| Constituent | Percent by Volume |
| Nitrogen (N2) | 78.084 |
| Oxygen (O2) | 20.946 |
| Argon (Ar) | 0.934 |
| Carbon dioxide (CO2) | 0.036 |
| Neon (Ne) | 0.00182 |
| Helium (He) | 0.000524 |
| Krypton (Kr) | 0.000114 |
| Hydrogen (H2) | 0.00005 |

If we arrange different gases in decreasing order of their percentage...
Explanation:
The correct answer is option 'D' - Nitrogen, Oxygen, Carbon Dioxide, and Hydrogen.
Reasoning:
In Earth's atmosphere, gases are present in different percentages. The composition of the Earth's atmosphere is primarily made up of Nitrogen, Oxygen, Carbon Dioxide, and trace amounts of other gases like Hydrogen.
The correct order of gases in decreasing percentage is as follows:
1. Nitrogen: Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the total volume. It is a colorless and odorless gas that is essential for the growth of plants and is also used in various industrial processes.
2. Oxygen: Oxygen is the second most abundant gas in the atmosphere, making up approximately 21% of the total volume. It is vital for the survival of most living organisms as it is involved in the process of respiration and combustion.
3. Carbon Dioxide: Carbon Dioxide is present in the atmosphere in much lower concentrations compared to Nitrogen and Oxygen. It constitutes only about 0.04% of the total volume. Carbon Dioxide plays a crucial role in the Earth's climate system as it is a greenhouse gas responsible for trapping heat and contributing to global warming.
4. Hydrogen: Hydrogen is a trace gas in Earth's atmosphere, present in very small amounts. Its concentration is less than 0.01%. Although it is not a significant component of the atmosphere, Hydrogen is important in various industrial processes and is also used as a fuel source.
Therefore, the correct order of gases in decreasing percentage available in the atmosphere is Nitrogen, Oxygen, Carbon Dioxide, and Hydrogen (option D).
The correct answer is option 'D' - Nitrogen, Oxygen, Carbon Dioxide, and Hydrogen.
