Assertion (A) : Thunderstorm is a violent convective event accompanied by thunder and lightening.
Reason (R) : Thunderstorm is not associated with vertical air movement, humidity and instability.
Choose the correct answer :
Assertion Analysis
Assertion (A) states that a thunderstorm is a violent convective event with thunder and lightning. This statement is factually correct. Thunderstorms are characterized by rapid upward movement of warm, moist air (convection), leading to the formation of cumulonimbus clouds, thunder, and lightning.
Reason Analysis
Reason (R) claims that thunderstorms are not associated with vertical air movement, humidity, and instability. This statement is factually false. In reality, these three factors – strong vertical air currents (convection), sufficient humidity, and atmospheric instability – are essential prerequisites for the development of thunderstorms.
Conclusion
Based on the analysis:
- Assertion (A) is true.
- Reason (R) is false.
Therefore, the correct option is the one stating that (A) is true, but (R) is false.
