Q. Which one of the following statements is correct?
✅ Correct Answer: (A)
Cirrus clouds are composed of ice crystals
Explanation:
Cirrus clouds are high-altitude clouds that form above 20,000 feet (6,000 meters).
- They are composed of ice crystals due to the cold temperatures at that height.
- These clouds appear thin, wispy, and feathery, often indicating fair weather but can also signal a change in the weather.
Why other options are incorrect:
- (B) describes Cumulus clouds, not Cirrus.
- (C) wrongly attributes the description of Cirrus clouds to Cumulus, which are actually dense and fluffy with a flat base.
- (D) is incorrect because Cumulus clouds are low to mid-level clouds, not high clouds.
Therefore, the correct and scientifically accurate statement is:
(A) Cirrus clouds are composed of ice crystals.
