If clouds are made of dirt, bacteria, and other stuff...than why do they look white, clean and fluffy?

Clouds are not composed of water vapour, they are composed of minute water droplets and/or ice crystals. Water vapour is the gaseous state of water and is invisible - just as nitrogen and oxygen are invisilble. The water droplets are very small - about a million are required to make a raindrop. Each droplet has a condensation nucleus - a minute particle of dust or salt - but most of it is water.





The water droplets scatter the white light from the sun just as a bowl of sugar or a field of snow does so the cloud appears white even though the individual droplets in it are transparent.

They aren't. They're made of water vapor.
Reply:Who told you that, clouds are water vapour and ice.
Reply:ice crystals it's very cold up there
Reply:Clouds are only made up of water vapor and dust particles. They have no color. They look white because sunlight is reflected by the water vapor.
Reply:because clouds are made up of billions of ice crystals.
Reply:Hmmm, recheck your facts.
Reply:becuase when you look at a cloud you see the water vapor, hence if there is any dust, bacteria, ect... you wouldnt to see anything but "white" becuase a cloud is nothing more than water vapor, and to go further there wouldnt be any dust or bacteria in a could becuase it is not a sponge just air and water thats all.
Reply:Actually, compared to the air down here on Earth, clouds ARE nice %26amp; clean! Clouds are like 99.999% -moisture... -so they ARE pretty clean. AND they have the ABILITY to clean the air- by washing out the polution in the air- by making the rain that cleans it up. So when Nature makes a "shower", you can thank those fluffy white clouds for washing out the gunk that WE put into the air!
