Water cycle

The water cycle is one of the most important natural processes that sustains human life and the natural environment. The water cycle works on two key processes: evaporation and condensation. But it is more complicated than that!

The key concept of the water cycle investigates the many processes involved in the natural water cycle, such as:

  • What are clouds and how are they formed?
  • What happens when water falls from the clouds and lands on the ground? Where does it go?
  • Where does groundwater come from?
  • How are the mountains, rivers and oceans connected?
