An examination of condensation forms in the atmosphere. It classifies clouds based on physical appearance, vertical extent, and altitude (high, middle, low), with focus on the convective mechanics of thunderous cumulonimbus clouds.
Correct Answer:
(D)
Condensation
Clouds are formed as a result of the process of condensation. Conversion of water in the gaseous state to a liquid or solid state is called condensation. clouds are a collection of very tiny droplets of water or ice crystals formed by condensation of water vapour in the atmosphere.
Ques: 2
Which of the following cloud is responsible for highly intense rain?
Correct Answer:
(C) Nimbostratus
Nimbostratus clouds are found very near to the surface of the Earth. They are dark grey with a ragged base. Nimbostratus clouds are associated with continuous rain.
Ques: 3
Highest altitude clouds are -
Correct Answer:
(D)
Cirrostratus
Cirrostratus are the highest altitude clouds. These are mainly formed at an altitude of over 18000 feet.
Ques: 4
Consider the following climatic and geographical phenomena:
Condensation
High temperature and humidity
Orography
Vertical wind
Thunder clouds development is due to which of these phenomena?
Correct Answer:
(C) 1, 2 and 4
Thunder cloud is a process of a thunderstorm. In fact, thunderstorms are a local lightning storm that develops in hot, humid tropical areas like India very frequently. The rising temperature produces strong upward rising winds. These winds carry water droplets upwards, where they freeze(condense), and fall down again. The swift movement of the falling water droplets along with the rising air creates lightning and sound. So, it is clear that except Orography, all are related to thunder clouds.
Ques: 5
During a thunderstorm, the thunder in the sky 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 code given below
Correct Answer:
(D)
None of the above
During a thunderstorm, thunder is the sound caused by a lightning discharge. Lightning heats the air in its path and causes a large over-pressure of the air within its channel. The channel expands supersonically into the surrounding air as a shockwave and creates an acoustic signal that is heard as thunder. Hence none of the above options is correct.
