liquid form.

7. Precipitation
Water falls back to earth in the
form of rain, hail or snow.

8. Collection
Water comes back to earth’s water
reserve.

9. Dew

Cumulus-the word cumulus means

15. Stratus cloud

16. Cumulus cloud

17. Fog
Fog is cloud near the ground. When the water vapor
near the ground is cooled and condenses into tiny
water droplets, fog is formed.

19. Precipitation
Is moisture falling from the air to the
ground.

20. Examples of Precipitation
1. Rain- water falling from the sky when the
temperature is above 0 degrees C.
2. Snow- is formed when the temperature is
below freezing point of water.
3. Hail- falls in the form of lumps of ice. It
happens in summer.
