1. CLOUDS

2. Today, we’ll learn how water in the air creates CLOUDS.
Friday, we learned about WATER in the atmosphere…
Today, we’ll learn how water in the air creates CLOUDS.

3. What are CLOUDS? They are made of tiny water droplets or ice crystals.
They form when water condenses onto small particles in the air (like dust).

4. How TINY are the water droplets?

5. How do clouds form? 1) Warm, moist air rises and cools.
3) Water vapor condenses forming a cloud.
2) Air cools to dew point causing condensation.
How do clouds form?

6. Clouds are NOT all the same…

7. Clouds are classified according to SHAPE
Flat clouds =
“Stratus”
Fluffy clouds =
“Cumulus”
Wispy clouds =
“Cirrus”

8. Clouds are also classified by ALTITUDE
On your blue paper, draw the different types of clouds (using chalk and charcoal).
*Use your textbook (pg. 111) and the cloud charts.*
Label each type of cloud.
Paste the paper into your science notebook.
HIGH LEVEL (cirro-)
MID LEVEL (alto-)
LOW LEVEL (stratus)

9. Spot the cloud!
Low and flat …..
STRATUS

10. Spot the cloud!
Middle level,
fluffy …..
Alto-Cumulus

11. Spot the cloud!
High level,
wispy …..
Cirrus

12. Spot the cloud!
Rain bearing,
storm clouds …..
Cumulo-Nimbus
