Question

Which is the layer of atmosphere very ideal to fly aeroplanes?

• A. Troposphere
• B. Stratosphere
• C. Mesosphere
• D. Thermosphere

Hint:

Remember the order of the atmosphere layers from the ground up: \textbf{T}roposphere (\textbf{T}rouble/Weather), \textbf{S}tratosphere (\textbf{S}table/Planes), \textbf{M}esosphere (\textbf{M}eteors), \textbf{T}hermosphere (\textbf{T}hin/Satellites).

Answer 1

The Correct Option is B

Step 1: Understanding the Question
The question asks to identify the layer of the atmosphere that is most suitable for commercial air travel.

Step 2: Analyzing the Layers of the Atmosphere


(A) Troposphere: This is the lowest layer, extending from the ground up to about 8-15 km. It contains about 80% of the atmosphere's mass and almost all of its water vapor, which means this is where weather (clouds, rain, storms, turbulence) occurs. While planes take off and land in the troposphere, it is not ideal for cruising.

(B) Stratosphere: Located above the troposphere, this layer is characterized by stable, dry air and very little weather or turbulence. This stability makes it the ideal layer for long-distance commercial flights, as it provides a smoother ride and better fuel efficiency. The ozone layer is also located here.

(C) Mesosphere: Above the stratosphere, this layer is where most meteors burn up. The air is too thin for conventional aircraft.

(D) Thermosphere: The outermost layer, where the air is extremely thin. This is where the International Space Station orbits.


Step 3: Final Answer
The Stratosphere is the ideal layer for flying airplanes due to its stability and lack of weather disturbances. Therefore, option (B) is the correct answer.
