1. What type of Weather do pressure systems bring?

2. What happens to the density of air as it is warmed? Cooled?
See Pg. 45R

3. How does the density of air affect if air rises or sinks? See pg. 43

4. What happens to air pressure on a warm day? Cold day? See pg 46L

5. What type of air pressure brings rain? See pg 47

6. Water Cycle Animation

9. What type of weather does warm air bring? Cold air?
Clear Skies
Precipitation

10. Homework: On pg.49R create a model of H/L pressure systems
Low Pressure = Precipitation
High Pressure = Clear Skies

11. Group Model
Work with your group to create a model of what is happening at a:
Low pressure system (L)
High pressure system (H).
Include: pressure, density, temperature and weather
Reminder: When we create models we always include:
A drawing
Clear labels
Description

12. Add any new information you gained from your group to your final Model on Pg49L.
High Pressure
Low Pressure
