2. 4. It is not very windy today, why is that? 5. Describe 3 different ways to increase the pressure on the air in a balloon. 6. If we traveled to Venus without a space suit, what would happen to us due to the atmospheric pressure being almost double Earth’s? What other problems would we have and why? End

4. * Based on temperature * Troposphere * Low, dense, thin * Weather * Stratosphere * Thicker, less dense, warms * Ozone * Protect from UV * Why do we need this protection?

5. * Mesosphere * Cold * Thermosphere * Warm * Exosphere * Ionosphere * Upper mesosphere to exosphere * Contains ions * Location of aurora

6. 7. What is the name for the lowest layer of the atmosphere? (The one we live in) 8. Air moves from _____ pressure to _____ pressure. 9. What are the two most common gasses in our atmosphere? 10. How is the troposphere heated? Stratosphere? Thermosphere? 11. What can water do that other liquids can’t? End

7. * Video Video * Adhesion * Definition * Example * Cohesion * Definition * Example * Surface tension * Definition * Example Example

8. * Humidity * Relative humidity * 100% = saturated * Dew point * Effected by * Temperature * Pressure * Condenses * Visible with a “seed”

9. 12. Watch the demo. Record your observations. Using what we talked about in class, why did that happen? 13. What is wind chill? 14. What happens in the ionosphere? 15. If the dew point this morning was 42 o F, what does that mean will occur when the temperature outside reaches 42 o F? End

10. * What are they? * How do they form? * Warm, moist air rises * Cools * Reaches dew point * Condenses * Need a solid to start the process, “seeds” * Types * Cirrus * Cumulus * Cumulonimbus * Stratus

11. * Enough needs to condense to be heavy enough to fall * Air temp. determines type * Types * Rain * Snow * Gas to solid in air * Hail * Liquid to solid in cloud * Get larger inside cloud
