Sources for haze particles include farming (ploughing in dry weather), traffic, industry, and wildfires.
That's because clouds are composeâ¦d of water droplets - liquid water, or water ice - tiny ice crystals. Either way, clouds are not invisible water vapor. Clouds can form as water vapor condenses to form tiny droplets of liquid water. These droplets can come together - coalesce - to form larger droplets. You've seen fog. Fog is a cloud at ground level. And if you've seen fog, then you've seen that clouds are composed of tiny water droplets suspended in air.
