Q

Which cloud commonly produces a halo about the Sun or Moon?

🔍 Key Concepts

• High-level vs mid-level clouds and how their ice crystal content affects optics • The typical appearance and altitude of cirrus-family clouds • Which clouds are most associated with optical phenomena like halos, sundogs, and coronas

💭 Think About

• Think about which cloud types are composed mainly of ice crystals at very high altitudes—these are most likely to bend and refract light from the Sun or Moon. • Compare the cloud types listed: which ones form thin, veil-like layers that cover much of the sky, rather than puffy or layered mid-level decks? • Recall from basic meteorology: which specific high cloud is known for creating halos and often precedes a warm front?

✅ Before You Answer

• Verify which option is a high-level (cirrus family) cloud rather than mid-level (alto) cloud. • Check which cloud type is typically thin and uniform, allowing the Sun or Moon to be seen through it with a distinct ring. • Confirm that the cloud you pick is commonly associated with ice crystals rather than mostly liquid water droplets.
