Q. During the 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.
- 1 only
- 2 and 3
- 1 and 3
- None of the above
Answer: (d) None of the above
Notes:
- Lightning is the most spectacular element of a thunderstorm. Lightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F). This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.
- Thunderstorms result from the rapid upward movement of warm, and moist air.
- They can occur inside warm, moist air masses and at fronts.
- As the warm, moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of over 20 km (12.45 miles).
- The thunderstorms are associated with the cumulonimbus clouds.
- These clouds normally form on warm sunny days but they can also be found on the cold front.
- From above it is clear that thunder in the sky is not produced by the meeting of cumulonimbus clouds in the sky.
