QUIZ - 96

The idea for this Quiz on Clouds was planted in my head by a person whose twitter handle is Blue Sky (in translation). Since the last Quiz was on Wind, I decided to do a series on the 5 elements of nature – Wind, Sky (Clouds), Fire, Water and Earth. The Ash Cloud from the erupting volcano in Iceland is a curious coincidence and not the inspiration for this Quiz.
