- 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 code given below:
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) None of the above produces the thunder
Answer: (d)
Thunderstorms develop in hot, humid tropical areas like India very frequently. The rising temperatures produce strong upward rising winds. These winds carry water droplets upwards, where they freeze, and fall down again. The swift movement of the falling water droplets along with the rising air creates lightning and sound.
O A thunderstorm is a well-grown cumulonimbus cloud producing thunder and lightning. When the clouds extend to heights where sub-zero temperature prevails, hails are formed, and they come down as hailstorms. If there is insufficient moisture, a thunderstorm can generate dust storms.
O A thunderstorm is characterised by an intense updraft of rising warm air, which causes the clouds to grow bigger and rise to a greater height. This causes precipitation. Later, downdraft brings down to earth the cool air and the rain.
O From severe thunderstorms sometimes spiralling wind descends like a trunk of an elephant with great force, with very low pressure at the centre, causing massive destruction on its way. Such a phenomenon is called a tornado. Tornadoes generally occur in middle latitudes. The tornado over the sea is called a waterspout.
Option (d) is correct: None of the given reasons explains the production of thunder in the sky during a thunderstorm.
