the water cycle BY: MARLEE RATH

What is the Water Cycle and why is it important for us to know about it?

  • The water cycle is the journey that water takes from land to sky.
  • The water cycle includes the different physical forms that water appears in as it repeats that cycle.
  • Every living thing needs water to survive, which makes an understanding of how water naturally supports all life on this planet pretty very important!


1. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). Water vapour droplets join together to make clouds!

2. Condensation: This is when water vapour in the air cools down and turns back into liquid water.

3. Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.

4. Collection: This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Most will infiltrate (soak into) the ground and will collect as underground water.

The water cycle is powered by the sun's energy and by gravity. The sun kick-starts the whole cycle by heating all the Earth's water and making it evaporate. Gravity makes the moisture fall back to Earth.
