1. Cloud Formation

2. What are Clouds? Condensation of water vapor

3. Condensation Nuclei Small particles that are suspended in the air

4. Convection cooling Lowering of air temperature due to the its rising and expanding Expansion cools air Compression warms air This is how most clouds form

5. Adiabatic Temperature Change Change in temperature due to expanding and compressing air

6. Sunny day, One area of Earth warms faster than another The air above warms by conduction Warm air rises, expands, and undergoes adiabatic cooling Temperature is lower than the dew point moisture in the air condenses Condensation forms clouds

7. Forced Lifting Mountain tops

8. Temperature 2 bodies of moist air that have different temperatures will result in condensation and clouds

9. Advective cooling Warm moist are is carried across cool land or water by the wind
