1.What layer of the atmosphere does weather changes occur? 2. Which layer of the atmosphere has the most air? 3. What layer of the atmosphere contains the ozone layer?

4. Find the air pressure (hPa) at the Following altitudes? a. 0 km. _____________ b. 20 km. ____________ c. 40 km. ____________ d. 60 km. ____________ 5. Find the highest and the lowest temperature: a.Troposphere Highest Temperature _________ Lowest temperature _________ b. Stratosphere Highest Temperature _________ Lowest temperature __________

Highest Lowest

6. Find the air pressure at the following locations. a. Station A at sea level: _______________________ b. Station B at the slope of the mountain: ________________________ c. Station C at the top of the mountain: ________________________ 7. What happens to the air pressure as you go up the mountain? Think! ______________________________

High Altitude Low air pressure Low Altitude High Air Pressure High Altitude Low air pressure Low Altitude High air pressure

8.What causes the eardrums to pop? 9.When do eardrums pop in? 10. When do eardrums pop out? 11. What is the relationship between altitude and air pressure? Low Altitude High air pressure High Altitude Low air pressure High Altitude Low air pressure Low Altitude High air pressure

8.What causes the eardrums to pop? Change in air pressure. 9.When do eardrums pop in? When air pressure changes from low to high. 10. When do eardrums pop out? When air pressure changes From high to low. 11. What is the relationship between altitude and air pressure? Higher altitude has lower air pressure.

12. How do cyclones form? Rising warm air and sinking cold air causes the air to spin counterclockwise in the Northern hemisphere.

The lines around the H and L are called ISOBARS. Isobars are lines of equal atmospheric pressure. Isobars Increasing by 4 towards the center. H Isobars decreasing by 4 towards the center. L Warm Front Cold Front H

13.What are the air pressures towards H? What is the interval between air pressures? 14.What are the air pressures towards L? What is the interval between air pressures? 15. What do you call the lines of equal atmospheric pressure?

16. How do you use the isobars to find the windy areas?

Windy area because the isobars are near each other. Not windy area because the isobars are far from each other. The closer the isobars from each other the stronger the winds in the area.

17. What is Atmospheric Pressure? the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly pounds per square inch). Also called barometric pressure. barometric pressure

The lines around the H and L are called ISOBARS. Isobars are lines of equal atmospheric pressure.

High Altitude Low air pressure Low Altitude High air pressure Your eardrum pops inward when you go down, and outward when you go up. The change in air pressure as you go up or as you go down is responsible for the popping of eardrums. High Altitude Low air pressure Low Altitude High air pressure
