During a thunderstorm, the thunder in the skies is produced by the
- Meeting of cumulonimbus clouds in the sky
- Lightning that separates the nimbus clouds
- Violent upward movement of air and water particles
Select the correct answer using the codes given below
Detailed Explanation:
❌ Statement 1 – Incorrect: The meeting of cumulonimbus clouds does not produce thunder; thunder is caused by lightning, not cloud collision.
❌ Statement 2 – Incorrect: Lightning does not separate clouds; rather, the intense heat from lightning causes rapid air expansion, which produces thunder.
❌ Statement 3 – Incorrect: Violent upward movement of air and water particles creates storm conditions and lightning, but thunder itself is the sound wave from lightning-heated air expansion.
Correct mechanism: Thunder is produced when lightning heats the surrounding air to approximately 30,000°C, causing it to expand explosively and create a shock wave heard as sound.
