Rain is one of most important natural process for our life. It makes people feel comfortable. How does rain form? Let me introduce for you. Rain is a drop of water falling from the clouds, when the sun is shining and the air is war...
(ice cooled the water vapor inside the jar; the water vapor changed, orcondensed,into water droplets/a cloud formed)How does this experiment help you to understand how clouds form in the sky?(water evaporates from land; as water vapor rises into the atmosphere, it cools; the water vapor c...
Stephen Studd/Stone/Getty Images To understand how clouds form, we need to take a step back and examine the processes ofevaporationandcondensation. Picture a birdbath outside on a hot day. When the temperature of the environment is warm, molecules ofwater(H2O) are energetic and can move more...

Where Does Rain Come From? Rain comes from clouds and clouds are formed by water vapor rising in the air. These water molecules will clump together and eventuallyform a cloud you can see.These water droplets will attract more water droplets and the cloud will get heavier and heavier. ...
This is condensation. When the water drops are too heavy to be in the air, they fall out of the clouds as rain. The rain runs into the Earth's seas, rivers and lakes. Then the cycle starts all over again! ( ) 1. Where does the tiny water in the air come from? A. The rain....
