Water Cycle

Standard 3b. When liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.

Standard 3c. Water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow.

1. Review of Wind

Last week you learned about wind and convection currents.

When two currents come together, it makes wind. If one current is very cold and the other current is very hot what happens?

It creates a very gentle breeze.
It creates a mild wind.
It creates a very strong wind

Which of these is true?

Colder air rises up and warm air sinks down.
Warm air rises up and colder air sinks down.

2. How old is your water?

Did you know that the water that comes out of our water fountains is the same water that dinosaurs splashed in as they waded through lakes and rivers. How is that possible?

3. What is a cloud?

A cloud is made of tiny water droplets (or ice crystals) that are in the air. If the droplets become large enough, they may be visible as a cloud or fog.

4. Where do the droplets come from?

So, where do the droplets come from?

This is similar to the way you separated salt from water.

Do you remember this?

This is a mini water cycle that you can make.

5. Where is all the water?

Now you know how Earth's water goes in a circle from liquid to gas back to liquid again. Water is in the air, in rivers and lakes, oceans and as a solid in glaciers. Click to look at this. Where is most of the Earth's water?

glaciers
rivers and lakes
oceans

	This graph shows where all of the Earth's water can be found. There's not much for us to drink!
	Only 1% of all Earth's water is drinkable.
	2% is frozen in glaciers.
	The other 97% is found in the ocean
