3. Atmosphere - 100
In which layer of the atmosphere does most of our daily weather take place?

4. Atmosphere - 100
Troposphere

5. Atmosphere - 200
What causes the absorption of ultraviolet light in the stratosphere?

6. Atmosphere - 200
Ozone O3

7. Atmosphere - 300
What happens to the temperature of air as it rises up from the ground?
Explain why!

8. Atmosphere - 300
Air cools as it rises (adiabatic cooling) because the gas expands due to decreasing atmospheric pressure

9. Atmosphere - 400
Does humid air have a greater or lesser density than dry air?
Explain why!

10. Atmosphere - 400
Humid air is less dense, because the water molecule has less mass than the Nitrogen molecule, which makes up most of dry air.

11. Atmosphere - 500
Name 3 greenhouse gases, and explain the greenhouse effect.

12. Atmosphere - 500
Carbon dioxide, methane, water vapor, are all greenhouse gases
Short wavelength UV light is absorbed by the Earth and re-radiated back to space as long wavelength UV. These long wavelengths are absorbed by greenhouses gases, “trapping” the heat in the atmosphere.

13. Storms - 100
Where do Hurricanes get their energy?

14. Storms - 100
The sun’s energy evaporates sea water into the air. The condensation of millions of gallons of this water in the atmosphere (as clouds) releases huge amounts of energy, which give hurricanes their power.

15. Storms - 200
Give two other names for hurricanes.

16. Storms - 200
Cyclone, typhoon, willi willi

17. Storms - 300
What direction do all low pressure system storms spin in the northern hemisphere?

18. Storms - 300
Counterclockwise and towards the center

19. Storms - 400
Why does a tornado funnel cloud “vacuum” up materials from Earth?

20. Storms - 400
Tornadoes vacuum up materials because of the extremely low pressure in the center of the funnel.

21. Storms - 500 For a thunder storm:
a) give the name of the cloud type associated with thunder storms
b) describe how a thundercloud forms
c) What type of fronts are thunderstorms often associated with?

22. Storms - 500 A) cumulonimbus cloud
B) hot spots or uplifting of warm air by fronts causes condensation of water droplets in the form of tall thunderheads
C) Thunderstorms often form when a cold front pushes warm air up

23. Weather Prediction - 100
As air temperature increases, what happens to air pressure?

24. Weather Prediction - 100
Warm air is less dense, so warm air has lower air pressure. Cold air is more dense, so cold air has higher pressure

25. Weather Prediction - 200
Simple barometers can be used to predict the weather. What type of weather is coming if the barometer indicates falling air pressure?

26. Weather Prediction - 200
Falling barometer (decreasing air pressure), means a low pressure system is coming. Low pressure systems are associated with stormy weather.

27. Weather Prediction - 300
In what type of storm have the highest wind velocities been measured?
How high can the wind speed get in such a storm?

28. Weather Prediction - 300
Tornadoes have the highest wind speeds, up to 350 mph.

29. Weather Prediction - 400 Name the 5 different types of precipitation.
Explain how they are all different from each other.

30. Weather Prediction - 400 Rain, snow, sleet, freezing rain, hail
Rain is liquid water drops, snow is ice crystals formed in the atmosphere, sleet is rain drops that falls through a cold air layer and freezes into ice drops, freezing rain is rain the lands on a cold surface and freezes into ice on the surface, hail is large balls of ice that form in thunder clouds from repeated melting and refreezing in strong updrafts in the cloud.

31. Weather Prediction - 500
Air with a temperature of 60 degrees F and a relative humidity of 51% is warmed to a temperature of 71 degrees F, but the relative humidity is still 51%. How did the moisture content of the air change?

32. Weather Prediction - 500
Since warm air can hold more moisture, the 71 F air must have a higher moisture content at 51% relative humidity than 60 F air at 51% relative humidity.

33. Climate - 100
How does elevation affect climate?

34. Climate - 100
The higher the elevation, the cooler the climate

35. Climate - 200
City A and City B are at the same latitude and elevation, but City A is near the ocean and City B is inland. Describe how the climates of these two cities are different.

36. Climate - 200
Large bodies of water moderate the climate: so at City A near the coast, winters are milder, summers are not as hot. At City B inland, winters are colder and summers are hotter.

37. Daily Double
Climate - 300
List the 6 major factors that influence climate

38. Climate - 300
Latitude, elevation, proximity to large bodies of water, ocean currents, prevailing winds, mountain barriers

39. Climate - 400
City X and City Y are both at the same elevation and latitude, but are separated by a mountain range. City X has a hot dry climate, and City Y has a cool humid climate. Explain this difference in climate between the two cities.

40. Climate - 400
Mountain ranges intercept the prevailing winds, causing the air to rise over the mountains. Rising air expands and cools, causing condensation and dropping rain on the windward side of the mountain (City Y). As the air goes over the mountain and down the other side, it sinks and warms, causing arid conditions on the leeward side (City X)

41. Climate - 500
Describe and explain the climates at the following latitudes:
equator
30 degrees N or S
60 degrees N or S
the poles

42. Climate - 500 Equator: rising air, wet (tropical rainforest)
30 degrees: sinking air, dry (desert)
60 degrees: rising air, wet and cool (temperate)
Poles: sinking air, dry and cold (polar)

43. Grab Bag - 100 List the 4 factors that affect evaporation rates
explain how they affect evaporation

44. Grab Bag - 100 Temperature: higher = faster evaporation
Surface area: more surface area = faster evaporation
Humidity: dry air = faster evaporation
Wind: more wind = faster evaporation

45. Grab Bag - 200
What is “wind” and what causes it?

46. Grab Bag - 200
Wind in the movement of air molecules from an area of high atmospheric pressure to areas of lower atmospheric pressure.

47. Grab Bag - 300
What device is used to measure relative humidity in the air?
A dry bulb reads 4 degrees C and a wet bulb reads -2 degrees C. What is the relative humidity?

48. Grab Bag - 300
sling psychrometer
14%

49. Grab Bag - 400 What is the definition of dew point?
Dry bulb reads 8 degrees C and wet bulb reads 6 degrees C. What is the dew point?

50. Grab Bag - 400
Dew point is the temperature at which water vapor condenses out of the air, forming liquid water (dew) on surfaces.
Dew Point is 3 degrees C

51. Grab Bag - 500
