2. CLOUDS

3. Objective 18:
I can identify the different types of clouds, and explain how clouds can be used to determine weather.

4. Clouds need 2 things to form:
Cooling temperatures
Condensation nuclei (particles in the air for water to condense on)

5. Cumulus – puffy cotton balls (nice day clouds)
Stratus – thick low level blanket, like on an overcast day (sometimes brings rain)
Cumulus – puffy cotton balls (nice day clouds)
Cirrus – high wispy, wind blown feathers (ice crystals inside)
Cumulonimbus – Thunderstorm clouds
(very tall, dark)

7. Which kind?

8. CIRRUS CLOUDS!

9. Which kind?

10. CUMULUS CLOUDS!

11. Which kind?

12. CUMULONIMBUS CLOUDS!

13. Which kind?

14. STRATUS CLOUDS!

15. Objective 19 I can describe relative humidity and dew point
Relative Humidity: The percentage of water vapor in the air compared to the maximum amount of water vapor the air can hold at a particular temperature.
***The closer the temperatures of the wet bulb and dry bulb temperatures, the higher the humidity will be
Dew Point – The temperature at which condensation begins.
