🔍 Key Concepts
• Water cycle (evaporation, condensation, precipitation)
• What happens to warm, moist air when it rises
• Role of cooling and condensation in forming visible droplets
đź’ Think About
• Think about what must happen to water for it to change from invisible water vapor into visible cloud droplets.
• When air rises, does it usually get warmer or cooler? How would that affect water vapor in the air?
• Which choices describe a change of state from gas (water vapor) to liquid (tiny droplets) rather than something unrelated like dry air or low humidity?
âś… Before You Answer
• Identify which option clearly involves warm, moist air rising.
• Check which option mentions cooling of that air and condensation into droplets.
• Eliminate any options that rely on dry air or say clouds form when humidity is low, since clouds involve high moisture content.
