No, they are not water vapor . That is the typical answer that they offer us when they teach us about the water cycle in school, that it evaporates from seas and rivers and clouds are formed when ascending. Not at all, outright lie. Or well, rather, it is a half truth.
If you think about it, it is obvious that it cannot be steam. Water in a gaseous state is invisible , and clouds are seen for miles, therefore, steam is discarded .
So what are they? Clouds are tiny droplets of liquid water in suspension , or frost if they are high enough. These small droplets remain in the air due to their small size, which ranges from 0.2 to 0.3 mm in diameter.
They only fall as precipitation when they measure between 1 and 5 millimeters. Its characteristic white color is due to the sunlight that falls on these droplets, which reflect the visible colors that make up the light, thus leaving the mixture of all of them, that is, white.
