Verified Answer
During a thunderstorm, the thunder in the skies is produced by the: 1....
  • Thunderstorms result from the rapid upward movement of warm, 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 cold front.  
  • But this question is asking about the Thunder i.e. the sound produced. The lightning generates between 100 million and 1 billion volts of electricity and can heat the air to around 50K°F. The rapid expansion causes the shock waves. Thunder happens because the lightning would heat the air at huge temperatures and the air expands so fast that it makes a loud clap of thunder.

During a thunderstorm, the thunder in the skies is produced by the: 1....
Explanation:
Thunder is the sound produced by lightning. When lightning occurs, it heats the surrounding air to temperatures up to 30,000 Kelvin. This sudden heating causes the air to rapidly expand, creating a shock wave that travels through the atmosphere as sound. Therefore, the correct answer is option 'D' as none of the options mentioned in the question produces thunder.

Let's discuss each option in detail:

1. Meeting of cumulonimbus clouds in the sky:
Cumulonimbus clouds are large, dense, and vertically developed clouds that are associated with thunderstorms. However, the meeting of these clouds in the sky does not produce thunder.

2. Lightning that separates the nimbus clouds:
Lightning is one of the primary causes of thunder. However, lightning does not separate nimbus clouds. Lightning is an electrical discharge that occurs between two charged regions within a cloud or between a cloud and the ground.

3. Violent upward movement of air and water particles:
The upward movement of air and water particles is associated with thunderstorms. However, this movement alone does not produce thunder. It is the sudden heating and expansion of air caused by lightning that produces thunder.

In conclusion, thunder is produced by lightning and the sudden heating and expansion of air caused by it. None of the options given in the question produce thunder.
