Example: STUDENT A: When H₂0 falls from clouds it’s called a rain.
STUDENT В: Where did you say it falls from? or
What form did you say it falls in?
STUDENT A: I said it falls from clouds. or

   If the slush freezes again and becomes hard and solid, it’s called ice.
   
4. 
   The combination of rain and snow is known as sleet.
   
5. 
   Small round lumps that fall during a thunderstorm are called hail.
   
6. 
   The H₂0 forming on the leaves and flowers is a dew in warm weather.
   
7. 
   The same in cold weather is frost.
   
8. 
   The H₂0 united into a liquid body which is relatively motionless may be a puddle, a pond, a lake, a sea, or even an ocean.
   
9. 
   While the water moves, it may be a brook, a creek or stream, or a river.
