Which of the following cloud types is composed entirely of ice crystals and typically appears as thin, delicate, wispy white filaments high in the atmosphere?

💡 Solution & Explanation

Cirrus clouds form at high altitudes above 6,000 meters where temperatures are extremely low, causing them to be composed entirely of ice crystals rather than water droplets. Stratus clouds form low, uniform grey layers resembling elevated fog, while cumulus clouds exhibit fluffy, rounded heaps with flat bases. Nimbus is a prefix or suffix denoting rain-bearing clouds. High altitude cloud formations are frequently analyzed in meteorological studies across regional examinations.
