1. Do Now complete the worksheet
You have 6 minutes to complete the worksheet and place it in the exit bin. (once that yellow bar below reaches the end your time is up!)Work independently you can use your notes!
Take out science fair worksheet. Rip off the back and pass it up!

2. Pressure decreases with altitude
L.O: SWBAT explain clouds & precipitation.
Do Now: Some Things to Recall and one new thing!(3 min- indicated by blue bar)
What happens to pressure as altitude increases? ____________________________
What do we call energy transfer due to density differences? ____________________
What do you think happens to the temperature of a volume of air that expands? _____________
Pressure decreases with altitude
Convection
It Cools

3. L.O: SWBAT explain how clouds form.
Cloud: is tiny water droplets or ice crystals floating in the atmosphere.
What’s a “cloud”?
L.O: SWBAT explain how clouds form.

4. cloud needs a surface for water droplets to form on.
These surfaces are called condensation nuclei. There’d be no clouds, without condensation nuclei in the air (dust, smoke etc in the air)
L.O: SWBAT explain how clouds form.

5. L.O: SWBAT explain how clouds form.
CLOUD FORMATION:
L.O: SWBAT explain how clouds form.

6. Cloud Formation Warm, moist air rises (or is forced to rise)
*** YOU MUST KNOW THIS EXACTLY!!! *** This will be on the next quiz and couple of tests!!!
Warm, moist air rises (or is forced to rise)
As the air rises it expands and cools
If the air temperature cools to the dew point, condensation will occur
Water will condense on particles in the air called condensation nuclei

7. Primary Ways Clouds Form:
Convection
Topography
(Oragraphic Lift)
Convergence
Frontal Lift

8. Convection

9. L.O: SWBAT explain how clouds form.
Dewpoint temperature is here.
L.O: SWBAT explain how clouds form.

10. Convergence

11. Clouds form when air, rises, expands and cools to the dewpoint
Notice: here, When the air is cooled to 20 Celcius, (the Dewpoint) the cloud forms
L.O: SWBAT explain how clouds form.

12. Leeward Side: Air sinks, compresses and warms.
Oragraphic Lift
Leeward Side: Air sinks, compresses and warms.
This side would be dry
Windward Side: Air rises, expands and cools.
This side would get clouds and precipitation

13. N. Donohue Pismo Beach, CA 2005
Sea Breeze
The hill forces the air to rise. As the air rises, it expands and cools to the dew point. Condensation occurs and a cloud forms on the windward side.

14. These pictures “PRECIPITATION” what is precipitation?
Precipitation: water (rain, snow & hail) falling from the sky.
These pictures “PRECIPITATION” what is precipitation?
L.O: SWBAT explain how clouds form.

15. L.O: SWBAT explain how clouds form.
Precipitation: happens because the water droplets have grown too big to stay aloft in the atmosphere
L.O: SWBAT explain how clouds form.

16. A rain gauge: Measures amount of rainfall in inches or centimeters
L.O: SWBAT explain how clouds form.
