Which description best matches cirrus clouds?

• A. They are wispy, high-level ice crystals
• B. They are low-level, heavy clouds
• C. They are thick, dark clouds
• D. They produce heavy rain

Answer: (A)

Cirrus clouds form high in the atmosphere where it's cold, so they are made of ice crystals. Their hallmark is a delicate, wispy, hair-like appearance that streaks across the sky. This combination—high altitude, ice-crystal composition, and a thin, feathery look—defines cirrus clouds. They aren’t heavy or dark and they don’t bring rain themselves; instead, they often signal that a weather system may be moving in. In contrast, low, heavy clouds tend to be thick and gray and can produce rain, which is not characteristic of cirrus.
