I am working on my take home quiz questions now...and i am not sure about the answers of the folowing questions...can anyone please help me to check???? THANKS A LOT!!!! (The "*" represents the answer I chose)
In the United States, early warning systems have not greatly reduced the amount
of damage caused by hurricanes.
* True
False
Smoke released from a stack into a very stable air mass would tend to
A) mix both upward and downward.
B) diffuse rapidly in all directions.
C) go almost straight up.
*D) spread out horizontally but not mix up or down.
E) mix rapidly downward.
The primary purpose of a smokestack is to
A) burn off inversion layers.
* B) change the lapse rate.
C) reduce the concentration of pollutants at ground level.
D) promote adiabatic cooling of the smoke.
Assume you live in an urban setting and an inversion is present. Which of these
best describes the visibility in your area if the inversion remains for 2 or 3 days?
A) Visibility improves greatly.
*B) Visibility gets steadily worse.
C) improves slightly
D) little or no change
27) Building tall smokestacks may improve local air quality.
* A) True
B) False
28) Air pollution affects weather, and weather affects air pollution.
* A) True
B) False
Sure, I can help you check your answers.
1) In the United States, early warning systems have not greatly reduced the amount of damage caused by hurricanes.
- Your answer: True
- Correct answer: False
To check the answer, you can look up information on the effectiveness of early warning systems in reducing hurricane damage in the United States. Research studies or reports from reputable sources like government agencies or scientific organizations can provide insights into this topic.
2) Smoke released from a stack into a very stable air mass would tend to:
- Your answer: Spread out horizontally but not mix up or down. (Option D)
- Correct answer: Spread out horizontally but not mix up or down. (Option D)
To check the answer, you can review the principles of air pollution dispersion in stable air masses. Understanding concepts like atmospheric stability, temperature inversions, and the behavior of smoke can help validate your choice.
3) The primary purpose of a smokestack is to:
- Your answer: Change the lapse rate. (Option B)
- Correct answer: Reduce the concentration of pollutants at ground level. (Option C)
To check the answer, you can analyze the function of smokestacks in industrial settings. Consider how they are designed to release emissions higher in the atmosphere to reduce their impact on ground-level air quality.
4) Assume you live in an urban setting, and an inversion is present. Which of these best describes the visibility in your area if the inversion remains for 2 or 3 days?
- Your answer: Visibility gets steadily worse. (Option B)
- Correct answer: Visibility gets steadily worse. (Option B)
To check the answer, you can understand the relationship between temperature inversions and air pollution accumulation. The longer an inversion persists, the more pollutants can accumulate near the surface, leading to reduced visibility.
5) Building tall smokestacks may improve local air quality.
- Your answer: True
- Correct answer: True
To check the answer, you can research the concept of stack height and its impact on air pollution dispersion. Consider factors like the elevation at which emissions are released and how it affects the local environment.
6) Air pollution affects weather, and weather affects air pollution.
- Your answer: True
- Correct answer: True
To check the answer, you can explore the interactions between air pollution and weather patterns. Consider how pollutants can be transported and dispersed through atmospheric processes, and how weather conditions can influence the formation and dispersion of air pollutants.
Remember, while these explanations can help you verify your answers, it's always important to consult reliable sources and study the relevant concepts to gain a deeper understanding of the topics.
