The Water Cycle

Remember the 4 stages as "Every Cloud Pours, then Collects" — Evaporation → Condensation → Precipitation → Collection.

🌏 In real life

Leave a glass of cold water out on a hot Chennai afternoon and droplets appear on the outside — that is condensation, the very step that builds clouds. The monsoon that fills our rivers is just this same cycle at a giant scale.

📝 Quick notes

  • The Sun's heat drives evaporation: liquid water turns into invisible water vapour.
  • High up, the cooler air makes vapour condense into tiny droplets that form clouds.
  • When droplets grow heavy they fall as precipitation — rain, snow or hail.
  • Water collects in rivers, oceans and groundwater, then the cycle repeats — no new water is ever created.

🎯 Test yourself

Which process turns liquid water into vapour, and what supplies the energy?

Evaporation; the Sun's heat supplies the energy.
