What you will learn

Explain evaporation, why rising air cools, how clouds form at the dew point, and why moist air near the sea brings more rain.

Use the sun slider to warm the sea and add water vapour to the air.
Lift the air higher and watch the thermometer readings fall.
See a cloud form where the air reaches its dew point, and rain when the cloud is thick and wet.
Finish three challenges, then try to find the coldest sea that can still make rain.
