**Explanation:**
The correct order in which the gases from the atmosphere disappear as one moves away from the surface of the earth is **Nitrogen-Oxygen-Carbon dioxide**.
1. **Nitrogen**: Nitrogen is the most abundant gas in the Earth's atmosphere, comprising about 78% of the total volume. It is a non-reactive gas and makes up the majority of the atmosphere.
2. **Oxygen**: Oxygen is the second most abundant gas in the atmosphere, making up approximately 21% of the total volume. It is essential for respiration and is necessary for most living organisms to survive.
3. **Carbon dioxide**: Carbon dioxide is a trace gas in the Earth's atmosphere, making up only about 0.04% of the total volume. It is a greenhouse gas and plays a vital role in regulating the Earth's temperature. However, its concentration decreases significantly as one moves away from the surface of the Earth.
As we move away from the surface of the Earth, the concentration of gases gradually decreases due to the decreasing atmospheric pressure. The atmosphere becomes thinner and less dense, resulting in the dissipation of gases. Nitrogen, being the most abundant gas, dissipates at a slower rate compared to oxygen and carbon dioxide. Oxygen, being the second most abundant gas, follows nitrogen in its dissipation. Lastly, carbon dioxide, being a trace gas, dissipates at a faster rate due to its lower concentration in the atmosphere.
Therefore, the correct order in which the gases from the atmosphere disappear as one moves away from the surface of the Earth is Nitrogen-Oxygen-Carbon dioxide.

The atomic mass of nitrogen is 14, oxygen is 16 and CO2 is 44 . Therefore the lighter gas moves away from the surface followed by the heavier ones
