On what essential weather ingredient do things like clouds, rain, and storms depend? |
water vapor |
|

|
|
As air cools, what happens to its relative humidity? |
It rises. |

|
On a hot, humid day, the windows of an air-conditioned building will sometimes be covered over with a dewy layer of water. What causes the windows to fog up? |
The cool air in the building makes the window less cool. When the hot, humid outside air comes into contact with the cool glass, the air cools below its dew point and deposits some of its water vapor through condensation onto the outside of the windows. |
