> Which type of cloud is fluffy and resembles a floating piece of cotton?And the answer: cumulus. Photo courtesy: thinglink.com[https://www.thinglink.com/scene/496033090708176898].Usually appearing in fairweather conditions, cumulus clouds are cauliflower-shaped and often described asfluffy or cotton-like. The name comes from the Latin term "cumulo," which meansheap or pile.Decorating the sky every day and night, clouds play an integral role in the lifeof every living thing on earth. These large groups of water droplets cling todust in the atmosphere, forming in any number of sizes and at many altitudes.Scientists have developed a system of classification based on their shape andaltitude that allows us to group any given cloud into a category. While therecan be many combinations of the category groups, the four main types are thecirrus, cumulus, stratus and nimbus.The highest clouds in the atmosphere are cirrus clouds. Latin for "curl ofhair," cirrus clouds are thin, wispy clouds that form high in the sky and aregenerally unaffected by weather. Due to the extremely cold temperatures high inthe atmosphere, they form out of ice particles and shine brightly white.Cumulus clouds are quite more robust in appearance. Often resembling puffycotton, the word "cumulus" is Latin for heap, or pile, much as their appearanceimplies. Cumulus clouds are vertically developing clouds, which means that theycan grow to towering heights (and often do!).Stratus clouds are thick, grey clouds that often appear foggy and hang low inthe atmosphere. In fact, these clouds are so low that they often form from fogthat has lifted off of the ground. The word "stratus" comes from the Latin wordfor layer – fitting, since it's stratus clouds we can thank for our grey,overcast days. The final main cloud type is the nimbus cloud. "Nimbus" translates to rain inLatin, as these downcast clouds are responsible for rain and thunderstorms.Affixing "nimbo-" to cloud types indicates the presence of rain or otherprecipitation.
