The stratosphere is indeed almost free from clouds and is considered ideal for flying aeroplanes. This layer also contains a protective layer of ozone gas, which shields us from harmful sun rays. This absence of clouds and associated weather phenomena makes it safer for aircraft to travel without encountering turbulent weather conditions.

The Stratosphere and Aviation
The stratosphere is a crucial layer of Earth's atmosphere that plays a significant role in aviation. Here’s why the statement about the stratosphere being almost free from clouds and ideal for flying aeroplanes is true:
Understanding the Stratosphere
- The stratosphere is the second layer of Earth's atmosphere, located above the troposphere and extending from about 10 to 50 kilometers (6 to 31 miles) above sea level.
- This layer contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.
Clouds in the Stratosphere
- Unlike the troposphere, where weather patterns and most clouds form, the stratosphere is relatively stable.
- It is characterized by a lack of vertical mixing, which means fewer clouds and turbulence compared to the troposphere.
Ideal Conditions for Flying
- The stability of the stratosphere provides a smoother flying experience, making it ideal for commercial flights.
- Pilots often prefer to fly at cruising altitudes within the stratosphere to avoid turbulence and adverse weather conditions that are common in the lower atmosphere.
Benefits for Aircraft
- The higher altitude reduces air resistance, allowing aircraft to operate more efficiently.
- The stratosphere's temperature profile, which generally increases with altitude, also contributes to optimal flying conditions.
In conclusion, the stratosphere's characteristics—minimal cloud cover, stability, and efficiency—make it an ideal layer for aviation, confirming that the statement is indeed true.
