Which of the following cloud types is characterized by fibrous, wispy ice crystal structures located at very high altitudes in the troposphere?

💡 Solution & Explanation

Cirrus clouds form at high altitudes exceeding six kilometers, consisting entirely of ice crystals due to freezing temperatures aloft, appearing thin and hair-like. Cumulus clouds are detached, fluffy masses with flat bases typically found at low to medium heights. Stratus clouds form uniform gray layers resembling elevated fog covering large sky areas without distinct outlines. Nimbus represents a traditional classification term denoting precipitation-bearing cloud systems.
