7. When do clouds form? - Check all that apply

• When condensation occurs.
• When evaporation occurs.
• Water vapor in air parcels meet colder surrounding air, and water vapor in the air parcel becomes liquid

8. What 'right conditions' would turn water vapor into a cloud? - Check TWO answers

• Energy transfers OUT of the air parcel causing it to cool; forming clouds and rain to fall.
• Energy transfers INTO the air parcel causing condensation, forming clouds and rain to fall.
• HEATING the air parcel turns the water vapor into liquid water, forming clouds and rain to fall.
• COOLING the air parcel turns the water vapor into liquid water, forming clouds and rain to fall.

9. What causes an air parcel to cool?

• A. Energy is transferred from the warmer air parcel to the cooler surrounding air.
• B. Energy is created as the air parcel moves faster.
• C. The air parcel gains energy from the ground as it rises.
• D. The air parcel's energy stays exactly the same as it rises.

10. Whenever you create a cloud with rain, what is the Final Air Parcel Temp after the rain has happened?

• The same as the surrounding air temp
• Higher than the surrounding air temp
• Lower than the surrounding air temp.
