How clouds form!

The water cycle video!

Why & how do clouds and the water cylce work closely together?

 The water cycle works REALLY closely together. The water cycle needs the clouds and the clouds are needed by the water. The water cycle as we know have 4 main processes: Evaporation, condensation, precipitation, & collection.  When the water condensates and forms water droplets and goes into the clouds.  And, water vapor collects through the air and dust particles, and form clouds. Eventually the precipitation in the form of, rain, sleet, snow, and hail. See, you know that the clouds and water cycle are really closely together, they basically need each other.  Without the clouds and water cycle we would not have water renewal.

How do clouds form?


Clouds have a wide variety of shapes and sizes. Clouds are made out of water & ice.   Clouds form when rising air, through expansion, cools to the point where some of themolecules "clump together" faster than they are torn apart by their thermal energy. Some of that water vapor condenses to form cloud droplets or ice crystals. There are many clouds, small, medium, and large. Clouds usually form when two weather fronts meet.

What is the water cycle?

The water cycle consist of four main things, evaporation, condensation, precipitaton, & collection. 
The earth has a limited amount of water. So we have to have the cycling of water. Therefore, thats how they get the name, "Water Cycle". Water covers about 71% of the earths surface. The water cycle constantly keeps going and never stops, because there is there is a constant supply of water. Everything needs water: plants, animals, and humans.
