The Water Cycle


Evaporation:
The graphic to the left shows H2O flying into the air. The H2O (or water as we shall call it) actually turns into a gas first. Water in gas form is called vapor. Vapor soars into the air, higher and higher until it is cooled.



Condensation:
To the left you can see a lovely graphic of a cloud.
When water vapor is cooled it becomes a liquid again. Water then floats on air and becomes fog or clouds.






Perspiration:
A graphic of rain to the left is linked to perspiration.
When a cloud is submitted to very cold air it will rain. All of the little water droplets that were riding on the air fall to the ground as rain. If submitted to extremely cold air, water can freeze and fall to Earth as snow or hail.



Infiltration:
To the left is a graphic of mud. When water hits the soil as rain it can create mud. Once water hits the ground it seeps into the earth. This is called infiltration. Soon it will find its way to the sea, which is where most water is evaporated. Then the cycle starts again.

This is quite good, Matthew. The graphics are clear, and the text is accurate.

I do wonder about the mud bit. You say the water seeps into the ground, then goes out to sea. We'll explore this concept soon.
