The Water Cycle

Water is all around us, but where does it come from? How does it travel from place to place? How do clouds form? Why don't the oceans overflow from rain? All of these questions can be answered by exploring the Water Cycle!

It's a Cycle!

This means that it happens over and over and over again. Look at the pictures below. They show you the important steps in the water cycle. Once the water goes through every step, the cycle starts over again.

Evaporation

First is Evaporation where the sun heats the water and turns it into water vapor.

Condensation

The water vapor begins to form clouds, this step is called Condensation.

Precipitation

Once the clouds get filled with water it begins to rain, this is called Precipitation.

After the water falls as precipitation, the whole cycle starts over again!

Bill Nye explains it all!

Bill will now take you through each step of the water cycle and give you some examples that you can relate to.
