  1. The Water Cycle To understand the processes involved in the water cycle

  2. What is Evaporation? It is the process of a liquid heating to form a gas

  3. What is Condensation? It is the process of a gas cooling to form a liquid

  4. The Water CycleWater is constantly moving between sea, air and land

  5. The Water CycleWater is constantly moving between sea, air and land The sun shines and the sea is heated heat

  6. The Water CycleWater is constantly moving between sea, air and land The water evaporates and forms clouds Evaporation

  7. The Water CycleWater is constantly moving between sea, air and land Condensation As air rises it cools and condenses. It reaches the ground as rain, snow, sleet or hail.

  8. The Water CycleWater is constantly moving between sea, air and land Snow forms Lakes form The snow melts and flows Rivers flow to the sea

  9. The Water CycleWater is constantly moving between sea, air and land The Water Cycle is complete

  16. The Water CycleWater is constantly moving between sea, air and land • Questions • Where does the water come from? • What happens to it when the sun heats it up? • As the vapour rises what happens to it? • Where does it go then? • How does the water get back to the sea?
