2. Mr. Nye’s Jeopardy

3. RULES 1.The team who answers correctly wins the point value of the question. 2.There are two daily doubles available. 3.If a team answers incorrectly for a daily double, then that team will lose the number of points that the question was worth, and any other team can “ring in” by holding up their answer at that point. Let’s play

4. 100 200 300 400 500 Final Jeopardy 100 200 300 400 500 The AirStorms Heating the Atm. Winds Water in the Atm. Weather Forecasts

5. The Air for 100 Earth’s ozone layer protects us from _________ radiation. ultraviolet

6. The Air for 200 Which layer of the atmosphere is the layer in which we live and also contains Earth’s weather? The troposphere

7. The Air for 300 As you go lower in altitude, air pressure will… increase.

8. The Air for 400 What are the two most abundant gases in the atmosphere? What percent of our atmosphere do these two gases make up? Nitrogen (78%) and oxygen (21%) Other gases- 1%

9. The Air for 500 What is the major source of air pollution? Describe how photochemical smog forms. Burning fossil fuels. Sunlight causes a reaction with pollutants in the air create a brownish haze called photochemical smog.

10. Storms for 100 What type of cloud indicates a thunderstorm is approaching? Give an example of a state that can receive very bad thunderstorms where tornadoes can form (in Tornado Alley). Cumulonimbus clouds; Oklahoma, Kansas, Texas, Nebraska, Iowa

11. Storms for 200 What type of low-lying clouds indicate that some light rain or drizzle may be on its way? Stratus clouds

12. Storms for 300 How does a cold front form? Cold air moves toward warm air and forces the warm air higher in altitude.

13. Storms for 400 How does lake effect snow form? Cold, dry air picks up moisture from the Great Lakes and dumps it as snow over land.

14. Storms DAILY DOUBLE!!! Hurricanes form over what type of water? Why do they form over this type of water? Warm, ocean water b/c the storm draws the moisture up from the warm water. Warm water vaporizes easier into a gas.

15. Heating the Atm. for 100 Energy that heats the air is called __________ radiation. infrared

16. Heating the Atm. for 200 Greenhouse gases ________ heat and may contribute to global _________. trap; warming

17. Heating the Atm. for 300 Heat transfer between the ground and the layer of air the ground is in contact with is called _________. The main method by which the troposphere is heated is by ___________. Conduction; convection

18. Heating the Atm. for 400 Is the air warmer just above the ground or a few feet up on a sunny day with no wind? Explain your answer. The air is warmer just above the ground b/c the ground radiates heat back into the atmosphere.

19. Heating the Atm. for 500 Explain how convection heats the troposphere. Include the relative density of each air mass in your answer. Denser cool air sinks, becomes heated from the infrared radiation from Earth’s surface, then rises b/c it’s less dense. This cycle continues.

20. Winds for 100 Winds flow because air moves from ________ to ________ air pressure Higher to lower air pressure

21. Winds for 200 What is the Coriolis effect? The effect of the Earth’s rotation on winds that makes them curve.

22. Winds for 300 Most air masses and storm systems move __________ to ________. What causes air masses and storms to move this direction in the United States? West to East; Prevailing Westerlies and Jet Streams

23. Winds for 400 Why do sea breezes occur? The air moves from the sea because it heats up slower than the land during the day.

24. Winds DAILY DOUBLE!!! Which city will have a smaller average yearly temperature change: San Diego, CA or Boston, MA. Explain your answer. San Diego b/c cool, humid air from the ocean blows West to East into the city, while in Boston air is moving to the city from over land.

25. Water in the Atm. for 100 A low-pressure center is called a _________ and usually brings ________ weather. Cyclone; cloudy and rainy

26. Water in the Atm. for 200 What’s the difference between evaporation and condensation? Which one is caused by heating? Which one is caused by cooling? Evaporation- liquid to a gas (via heating) Condensation- gas to a liquid (via cooling)

27. Water in the Atm. for 300 When do you sweat more: when the humidity is high or low? Explain why. High b/c the air cannot hold much more water vapor, so your sweat evaporates slowly.

28. Water in the Atm. for 400 Describe each type of air mass below in terms of the weather they bring to areas of the United States: maritime polar, maritime tropical, continental polar, continental tropical. Maritime polar- cold and humid Maritime tropical- warm and humid Continental polar- cold and dry Continental tropical- warm and dry

29. Water in the Atm. for 500 Suppose you were wearing glasses outside on a very cold winter day. What will happen to the glasses when you go back inside your home? If a substance forms on them, then where did this substance come from? They will fog up b/c water vapor condensed onto them from the air.

30. Weather Forecasts for 100 What instrument is used to measure air pressure? What does a drop in air pressure indicate in terms of weather. A barometer; stormy weather may be on its way.

31. Weather Forecasts for 200 Weather forecasts are more accurate because meteorologists are now able to gather more weather _______ and input this data in a ________ to predict the weather. Data; computer

32. Weather Forecasts for 300 What type of weather technology would better enable a meteorologist to follow the path of a thunderstorm? Doppler Radar

33. Weather Forecasts for 400 List 3 specific weather technologies that have caused an improvement in the collection of weather data. Computers, Doppler Radar, Weather Balloons, Weather Satellites, Automated Weather Stations

34. Weather Forecasts for 500 Draw a cold front heading North and an occluded front heading West. Then draw a stationary front. Cold front- triangles facing upward/North. Occluded front- alternating triangles and half-circles all facing left/West. Stationary front- triangles and half- circles facing opposite directions.

35. Winds Suppose you heard there are some storms throughout PA and wanted to know if any would be coming into Bellefonte. What direction should you look to see if a storm is approaching? Why? West, b/c winds move storms West to East in the U.S..
