1. The Water Cycle

2. What is a cycle?
The word cycle usually means circle. The water cycle is like a circle because it has no beginning or end. There really is no new water on Earth.

3. What is the Water Cycle?
The water cycle greatly affects weather and living things.
You might think that rain brings new water to Earth BUT there is no new water on Earth.
The water cycle is the movement of water between the ground and the atmosphere.

4. Questions True or False: The word cycle usually means square.
True or False: There is no new water on Earth.
True or False: The water cycle greatly affects weather and living things.
True or False: The water cycle is the movement of water between the ground and the atmosphere.

5. 1st step
The first step of the water cycle involves the sun. The sun heats water on Earth and changes it from a liquid to a gas called water vapor.
The water vapor goes into the air. This is called evaporation.
It is evaporation that dries a puddle in the sun after the rain.

6. The Second step
In the 2nd step of the cycle, water vapor in the air changes back to a liquid. This happens when warm air holding water vapor gets cooler. Its called condensation.
The tiny water drops in the air are packed closer and closer together until they start to join. Clouds are formed when thousands of drops are so close together that you cannot see through them.

7. questions The first step of the water cycle involves the ____________.
Sun moon snow
Condensation takes place when warm air holding water vapor gets ______________.
Warmer cooler wet
It is _____________ that dries a puddle in the sun.
Evaporation rain or snow atmosphere

8. The last step
As clouds become cooler, the drops join together to make bigger drops.
Finally, they become heavy enough to fall back to Earth as rain or snow.

9. Questions True or False: Clouds are formed when rain falls.
In the third step of the water cycle, rain or snow______.
Dries up goes into clouds falls back to Earth
As clouds become cooler, drops join together to make _____.
Smaller drops bigger drops vapor
