3. Water ( Sources )

4. Water (Uses)

5. Water Cycle ( Processes )
1. Evaporation
2. Condensation
3. Precipitation
4. Transpiration

6. 1.Evaporation - occurs when
the liquid water on the Earth’s
Surface turns into water vapor
in the atmosphere.
-it happens through the help
of heat energy coming from
the sun.

7. 2. Transpiration –
happens when plants
and trees release water
vapor in air.

8. 3. Condensation- warm
water rises up through the earth’s
atmosphere.
-As water vapor rises higher and
higher, the cold air in the
atmosphere causes it to turn back
into liquid water forming clouds.

9. 4. Precipitation- when a cloud
becomes full of liquid water, it
falls down from the sky as rain
or snow.
-rain and snow then fill the
lakes and streams and run
into the land.
