Nimbus cloud is best described as?

Nimbus cloud is best described as?

• A. Rain cloud; usually low, dark, and formless, sometimes spanning the entire visible sky
• B. Wispy, feathery clouds made of ice crystals
• C. Layered clouds that cover much of the sky and are dull gray
• D. Big fluffy clouds

Answer: (A)

Understanding that nimbus indicates rain-bearing clouds helps identify the best description. Nimbus comes from a term used to denote clouds that bring precipitation, so they tend to appear as dark, low-lying masses that can cover large portions of the sky. That lines up with the description of a rain cloud that is usually low, dark, and formless, sometimes spanning the entire visible sky. The other descriptions point to different cloud families: wispy, feathery ice-crystal clouds are cirrus; layered clouds that cover much of the sky are stratus; big fluffy clouds are cumulus. Thus, this rain-bearing characterization is the best fit for nimbus.
