Water vapor is one of the components of the air in the atmosphere.  What change causes the vapor  in the air to form clouds?

• A.  As air rises in the atmosphere, it becomes warmer and cannot hold as much water. 
• B. As air cools, water vapor in the air condenses to liquid or solid state. 
• C. Air rises, the water becomes heavier and changes form.

Where can you find water vapor in the air? 

• only in clouds             
• only as rain                     
•  everywhere
