2. What are clouds? http://retards.org/photography/dimage/photographs/2001/10/08/20011008_173048-800.jpg

3. Clouds are visible masses of ice particles or water droplets suspended in air. They are not a gas!!!

4. What does it take to make a cloud?

5. Cloud Ingredients: 1 – Water Vapor All clouds are made from water vapor that has condensed from the air.

6. Cloud Ingredients: 2 – Dew Point Temperature Air must be cooled to its dew point for condensation!

8. Cloud Ingredients: 3 – Condensation Nuclei A solid surface on which condensation can take place.

9. How do condensation nuclei get into the air?

10. Dust Storms http://www.mountwashington.org/notebook/images/drought/dust-storm.jpg

11. ash

12. Pollution (smoke)

13. Forest Fires- smoke

15. How do cloud droplets form? Vapor Coalesces

16. Cloud Formation: 1.Warm, moist air rises. 2.Rising air cools to its dew point. 3.Water vapor condenses on particle to form liquid cloud droplets.

17. * Clouds can only form in warm rising air!
