2. Name 2 things that happen in the troposphere.
Home

3. Possible answers: Weather, airplanes flying, birds flying, humans are in the troposphere!

4. What is the most abundant gas in the atmosphere
What is the most abundant gas in the atmosphere? (bonus 100 points if you can give the % of the atmosphere it makes up)
A-200

5. Nitrogen 79%
Home

6. What helpful feature is in the stratosphere?

7. The ozone layer.
Home

8. What layer of the atmosphere has the lowest air pressure and why?

9. The exosphere. It has the lowest air pressure because it has the least amount of air pushing down on it because it is the top layer of the atmosphere.

10. Explain 2 ways that the atmosphere protects us
Explain 2 ways that the atmosphere protects us. (bonus 100 points if you can name 3rd way)
A-500

11. Possible answers: 1. The atmosphere protects us from the sun making us too hot during the day by blocking some of the sun’s rays. 2. The atmosphere protects us from getting too cold during the night because it holds heat in. 3. The atmosphere protects us from the sun’s harmful UV rays, which can cause skin cancer. 4. The mesosphere breaks up most meteors that enter the atmosphere.

12. What is the difference between a cirrus cloud and a cumulus cloud?

13. Cumulus clouds are puffy and have a flat bottom, while cirrus clouds are feathery and pointy. Also, cirrus clouds are found about 8,000m high in the sky, while regular cumulus clouds are found at an altitude of 2,000m.
Home

14. What type of clouds produce thunderstorms, blizzards and tornadoes?

15. Cumulonimbus clouds
Home

16. Why are there storms happening at the cold front in the Eastern U.S.?
B-300

17. There are storms at the cold front because a warm front passed through the area ahead of the cold front recently. This warm front leaves warm air behind. When the cold front moves in, it meets the warm air and creates clouds and storms.
Home

18. B-400
Explain the different between a cold front and a warm front. Be sure to include the difference between what happens when the two meet.

19. When a cold front moves in on a warm air mass, the cold air pushes under the warm air because it is more dense. The warm air is pushed up quickly and this forms cumulonimbus clouds. When a warm front moves in on a cold front, the warm from slowly pushes out the cold front and long, blanket-like nimbostratus clouds form.
Home

20. Explain what is happening near the ‘L’ and why.
B-500

21. There are snowstorms and rain at the ‘L’
There are snowstorms and rain at the ‘L’. This is happening because a cold front is meeting with a warm front.
Home

22. What is the definition of a hurricane?

23. A rotating, tropical storm with strong winds.
Home

24. What 2 types of air combine to create conditions that can produce tornadoes?

25. Warm, moist air and cold, dry air.
Home

26. Describe what happens to the strength of hurricane when it reaches land and why this happens.

27. A hurricane loses strength when it reaches land because hurricanes gain their power from the warmth of tropical waters.
Home

28. Explain why so many tornadoes occur in Tornado Alley (Southeastern U.S.).

29. Tornadoes occur in Tornado Alley because this is where warm, moist air from the Gulf of Mexico often meets cold, dry air from Canada and the Northern U.S.. When warm, moist air and cold, dry air come together, conditions are right for tornadoes to form.

30. Is this a hurricane or a tornado
Is this a hurricane or a tornado? Explain at least 3 features that confirm your choice.
C-500

31. Hurricane. 1) The location of the trail on the map is over water, which indicates a hurricane. 2) The size of the trail indicate a hurricane because there are parts of the trail that are larger than entire states. 3) The distance traveled indicates a hurricane because the trail extends along almost the entire East coast of the U.S. 4) The time stamps on the trail indicate a hurricane because the time extends for more than 2 days, while tornadoes only last a few minutes.

32. Name the 4 steps of the water cycle.

34. Label each number (1-4) with the correct step of the water cycle.

36. What 2 steps of the water cycle does H2O undergo a phase change
What 2 steps of the water cycle does H2O undergo a phase change? Describe each change.
D-300

37. Evaporation: liquid to gas Condensation: gas to liquid
Home

38. Describe what happens during the “runoff” step of the water cycle.

39. Possible answer: During “runoff,” water falling from clouds lands on different parts of Earth’s surface. This water then flows back to nearby lakes, rivers and streams.
Home

40. Describe what happens during condensation.

41. During condensation, water vapor (gas) cools down to form very small water droplets that collect to form clouds.
Home

42. Name 3 difference sources people can obtain weather reports from.

43. Possible answers: TV, newspaper, internet, radio, five senses.
Home

44. About how long do most tornadoes last?

45. Anywhere from a few seconds to a few minutes.

48. E-400
Explain why the “Feels Like” temperature is different from the actual temperature on a thermometer.

49. The “Feels Like” temperature can be different than the temperature on a thermometer because of wind chill. Most thermometers cannot detect wind, but a person standing outside can feel colder because of the wind.

50. Mr. and Mrs. Green just purchased a house (X on map) on the Northern coast of Russia. Should they purchase hurricane insurance for their house? Explain why or why not.
E-500 X

51. Mr. and Mrs. Green should not purchase hurricane insurance because, even though their house is near water, hurricanes only occur in tropical areas near the equator. The North coast of Russia is far from these tropical areas.
Home

52. Final Jeopardy Question Explain, in at least 2 complete sentences, what causes changes in the weather.

53. Changes in weather are caused by the uneven heating of the Earth by the sun. The tropical areas are heated more than the rest of the planet, and that heat wants to spread out. Warm air masses move around the planet and collide with cold air masses, which creates clouds and other weather events.
