Run and get a glass of water and put it on the table next to you.  Take a good long look at the water.  Now — can you guess how old it is?



The water in your glass may have fallen from the sky as rain just last week, but the water itself has been around pretty much as long as the earth has!

When the first fish crawled out of the ocean onto the land, your glass of water was part of that ocean.  When the Brontosaurus walked through lakes feeding on  plants, your glass of water was part of those lakes.  When kings and princesses, knights and squires took a drink from their wells, your glass of water was part of those wells.

And you thought your parents were OLD

The Water Cycle


There are four mains stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let’s look at each of these stages.

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.

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

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

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 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 the earth.

It is the greatest recycler of all time!
