🔍 Key Concepts

• Cloud formation depends on air rising, cooling, and reaching its dew point • The role of relative humidity in producing condensation (clouds) • How temperature difference between surface and aloft affects rising air and cloud development

💭 Think About

• Think about what must happen to air for a cloud to form. Does it need to cool a lot relative to its starting temperature, or just a little? • If the air at the surface and the air aloft are the same temperature, what does that say about how easy or hard it is for air parcels to keep rising? • Which condition would make it hardest for rising air to cool to its dew point and form visible condensation?

✅ Before You Answer

• Identify which choice suggests stable air that resists vertical motion • Decide in which option rising air would be least likely to continue rising and cooling • Check which condition would keep the air farthest from its dew point, making condensation (clouds) less likely
