7. Let’s model some air pressure in atmosphere… Get into groups of 4. You need 4 books and 4 pieces of scratch paper! Get into groups of 4. You need 4 books and 4 pieces of scratch paper! Stack the books, between each book, put a piece of scratch paper. Make sure all the paper sticks out the same length. Pull out each piece of paper. Answer the following questions as a group on a piece of notebook paper. Stack the books, between each book, put a piece of scratch paper. Make sure all the paper sticks out the same length. Pull out each piece of paper. Answer the following questions as a group on a piece of notebook paper.

11. Atmosphere notes What is weather? The state of atmosphere at a given time and place What produces weather? Earth’s motion and heat from the sun

12. Atmosphere What is climate? Observations of weather over many years

13. Atmosphere The atmosphere is made up of air, which is mostly oxygen and nitrogen (99%). The rest of air is made up of argon, carbon dioxide and other compounds. Though, CO2 only makes up a tiny percentage of air, it affects temperature a lot! The atmosphere is made up of air, which is mostly oxygen and nitrogen (99%).

Other components of atmosphere are ozone, dust, and water vapor. The affect the absorption of heat and the reflection of light Other components of atmosphere are ozone, dust, and water vapor. The affect the absorption of heat and the reflection of light

14. Fast Fact! The aurora borealis (or “northern lights”) was believed to be a sign from the gods in the Middle Ages.

15. The layers… The atmosphere is divided into 4 layers that are based on temperature The atmosphere is divided into 4 layers that are based on temperature

16. Atmosphere Layers Activity Place the completed diagram inside your notebook. If you do not have glue you may draw the pictures in the layers in which they exist. Place the completed diagram inside your notebook. If you do not have glue you may draw the pictures in the layers in which they exist.

17. Atmosphere Layers

18. 1. Troposphere Where weather happens. Altitude increases and temperature decreases Where weather happens. Altitude increases and temperature decreases

19. Atmosphere Layers

20. 2. Stratosphere Temperature stays constant, then start to increase as altitude increases This is because there is a lot of ozone in the stratosphere and ozone absorbs the heat

21. Atmosphere Layers

22. 3. Mesosphere Altitude increases, temperature decreases Altitude increases, temperature decreases

23. Atmosphere Layers

24. 4. Thermosphere Upper limit! Upper limit! Temperature increases again because this layer is absorbing lots of sun’s radiation Temperature increases again because this layer is absorbing lots of sun’s radiation

25. How can I remember? T oo M uch S weet T ea

26. So… What does the ozone do? Protects all living things on Earth by blocking out harsh ultraviolet rays What does the ozone do? Protects all living things on Earth by blocking out harsh ultraviolet rays What layer is it in? Stratosphere What layer is it in? Stratosphere

27. THE HOLE IN THE OZONE IS NOT THE CAUSE OF GLOBAL WARMING. WHAT IS? CO2!
