A water-cycle adventure
Water travels between land, air and oceans in several forms.

Picture in words: 1. Evaporation: Liquid water gains energy and becomes invisible water vapour.
2. Condensation: Cooling water vapour can form tiny liquid droplets. Many clouds contain droplets or ice.
3. Precipitation: Water falls from clouds as rain, snow or other forms.
4. Collection: Water flows over land or into soil, rivers and oceans. It can take many different routes.

One more wonder: A cloud is not a bag of invisible water vapour: it contains tiny droplets or ice crystals.


Question: Which step forms tiny droplets from water vapour?
Answer: Condensation
