How do clouds form?

Clouds are formed when warm air cools. The excess water condenses out of tiny droplets of water. These droplets collide with other tiny droplets and get larger and heavier; these droplets come together and form a cloud until they fall as rain. Saturated air is c caused by warm, moist air get carried up into the atmosphere when it is cooler, or by the air being forced up over the top of the mountains. That is why clouds often go over mountains.


What are clouds made of?
A cloud is made up of water droplets and ice crystals and sometimes a cloud is made up of just water or both. Did you know that water droplet is smaller and lighter than a grain of flour and that it can float on air? Another fact is that there are 1 million cloud droplets in a droplet.
