2. Atmospheric Jeopardy!

3. The Air Around You Quality Control Under Pressure LayersPotpourri 10 20 30 40

4. The study of weather and the atmosphere is called… a)Forecasting b)Astronomy c)Meteorology d)Astrology

6. What are the 3 main gases that make up the atmosphere?

7. Nitrogen (78%) Oxygen (21%) Carbon Dioxide (~1%)

8. What 2 roles does water vapor play in the atmosphere?

9. Water vapor condenses to form clouds. Water vapor accumulates on particles and forms precipitation

10. The atmosphere provides 4 different benefits. What are 3 of them?

11. Back to Menu Final Jeopardy Oxygen, CO 2 Has important gases (Oxygen, CO 2 ). Traps heat, allowing for liquid water. Burns up most meteoroids. Absorbs dangerous UV radiation.

12. Pollutants are _______ ______s that can be found in land, in water, or in air.

13. harmful particles Pollutants are harmful particles that can be found in land, in water, or in air.

14. What are 3 sources of man- made pollution?

15. coal, oil, gas Burning fossil fuels (coal, oil, gas) Factories Farming Construction Motor vehicles

16. What are 4 natural sources of pollution?

17. Salt evaporated from the ocean Pollen from mold and plants Smoke Ash Volcanoes

18. Temperature Inversion The atmosphere around a city should normally look like this. Explain what a city experiencing Temperature Inversion would look like. Why is it bad?

19. Back to Menu Final Jeopardy Temperature Inversion causes a layer of warm air to appear between cooler layers. This traps pollutants where we breath – not good.

20. What is Density equal to?.

21. Density = Mass / Volume

22. Which side is more dense?

23. The right side – the same amount of mass (13g) is in a smaller volume.

24. What tool would you use to measure air pressure? What would it tell you about the pressure if you went down into a mine, or up into the air?

25. mercury or aneroid A barometer (mercury or aneroid) measures air pressure. high pressure low pressure In a mine, it would read high pressure. Up in the air, it would read low pressure.

26. hotcold Explain in detail how temperature, both hot and cold, affects the density of a gas.

27. Back to Menu Final Jeopardy At high temperatures, gases have more energy  means particles can move farther apart  increases volume  decreases density. Low Low temperatures have the opposite effect.

28. Troposphere What 2 things are important about the Troposphere?

29. It is where we live. Weather occurs there. Clouds form here. It is the thinnest layer.

30. Mesosphere What crucial function does the Mesosphere carry out?

31. Mesosphere The Mesosphere, the coldest layer, burns up meteors due to friction.

32. The Thermosphere is split into two layers. What are they, and what is special about each of them?

33. Ionosphere where radio signals and Aurora Borealis occurExosphere where satellites orbit They are the Ionosphere (where radio signals and Aurora Borealis occur) and the Exosphere (where satellites orbit).

34. Stratosphere Explain what the line on this graph represents and why it is increasing in the Stratosphere.

35. It shows temperature change with height. UV radiation It increases in the Stratosphere because the ozone there absorbs UV radiation. Back to Menu Final Jeopardy

36. Smoke is dark in color because it contains… a) Water vaporb) Carbon c) Sulfur

37. b) Carbon c) Sulfur a) Water vapor Smoke is dark in color because it contains…

38. What are 2 types of fog-related pollution? Explain how they form.

39. Smog Smog is a mixture of smoke and fog. Photochemical smog Photochemical smog is a reaction between light and chemicals in the air.

40. What is the most abundant gas in the atmosphere, and why is it important?

41. Nitrogen makes up 78% of the atmosphere. Living organisms need nitrogen to grow and repair cells.

42. Military pilots often fly at high altitudes. Why do they need to wear a mask at these heights?

43. Higher altitudes have lower air pressure, meaning lower density. Particles of oxygen are spread farther apart, so the mask provides oxygen. Back to Menu Final Jeopardy
