APES Unit 7 progress check: mcq
Which of the following is most responsible for the change in the omissions of volatile organic compounds (VOC) from 1970 to 2020 as shown in the graph?
An increase in admission standards that began in 1970 that regulated corporate average fuel economy (CAFE) standards
Which of the following is most likely responsible for the indoor air pollutant shown in the graph?
Cracks in the basement foundation
Which of the following best describes the efficiency of dry scrubbers at removing particles that are less than 2 micrometers in diameter?
Dry scrubbers are less than 10% effective at removing particles less than 1 pm in size
Which of the following claims is best supported by the evidence provided by the article?
Frog populations may decrease in size as a result of males changing the pitch of their calls
Which of the following claims is best supported by the data shown in the table?
Isoprene's contribution to ozone levels in Berlin was greatest in July of both years
The graph shows the average distance traveled by individuals in a population in an urban area in the south western United States. Based on the data, which of the following months most likely experiences the highest levels of photochemical smog?
July
Which of the following best describes the process shown in the diagram above?
Less-dense, warm air creates a temperature inversion between more-dense layers, trapping pollutants near the ground
Which of the following best describes how a scientist could accurately study the effects of soil buffering on plant growth in a region that is affected by acid deposition downwind of a coal burning power plant?
Measure the changes in plant height over a year in two different groups of trees the same distance from the power plant, one group is in topsoil and one group is in topsoil with lime stone added
Which of the following devices is correctly paired to the air pollutant it would be used to measure?
Measuring device: gas sensor pollutant measured: CO2
Based on the data in the graph, which of the following insulation options is ineffective at insulating a home and greatly contributes to indoor air pollution?
Mineral fiber bat
Which of the following methods would best identify changes from acid deposition in an area over time?
Monitoring the long-term chemical and biological parameters of ecosystem
Based on the authors claim in the article, which of the following statements best describes the effect of noise pollution on wildlife?
Noise pollution has a negative affect on wildlife activities such as meeting, establishing territories, and predator-prey interactions
Which of the following best describes the relationship between variables in the data table?
Ozone maximum is correlated to average and maximum temperature
Which of the following points on the graph best illustrates the location where pollutants are most likely to accumulate as a result of a thermal inversion?
Point D (on the bottom line)
What is one potential impact of increased noise pollution in national parks that is supported by the article?
Prey populations are likely to increase in national parks because predators have a decreased ability to hear prey sounds
Which of the following is the most likely reason for the trend shown in the graph of fluctuating indoor radon levels over the course of a year?
Radon levels tend to increase in the colder months because of the difference in temperature inside and outside the home, which creates a vacuum pulling radon into the home at a higher rate
Which of the following best describes the impact of modifying the slurry by increasing the amount of lime stone?
The amount of sulfur dioxide released will decrease
Which of the following best describes how their choice of control group could affect the results of the experiment?
The coal burning power plant would not appear to have to have a large impact because the pH levels of the two lakes would be similar
Scientists have been collecting atmospheric CO2 data for many years to monitor changes over time. Which of the following best describes why an island location, such as the Mauna Loa observatory in Hawaii, is an ideal location to measure global CO2 concentrations?
The location is far from any continent, providing atmospheric air samples that are less likely to be affected by industry and transportation
Air pollution from a power plant is being monitored for levels of nitrogen dioxide and ground level ozone. The levels are measured daily at the same time. Which of the following best predicts the impact of the dark and cloudy day on the readings for the levels of air pollutants measured?
There will be an increase in the level of nitrogen dioxide and a decrease in the level of ground level ozone
Based on the data in the graph, which of the following methods would be most effective at removing the greatest amount of particulate matter from coal-burning power plant emissions?
Wet scrubbers using a flow rate of 450 L/min are best suited to remove large particles
And air pollution expert set up a monitoring program to determine the amount of particle matter (PM) leaving a farmers field after crops were harvested in the soil was bare. She set up high volume air sampler is 10 m from each edge of the square field and collected samples weekly for two months. When she looked at her data, she was surprised by how much the (PM) levels buried, both from site to site on a given date and over time at each site. Which of the following parameters would have been best to measure to help explain the variation in her results?
Wind direction and speed
A researcher wants to determine if ponds and lakes downward of a coal burning power plants are affected by the plant emissions. Which of the following would be the best parameter from the water in the ponds and lakes to measure in order to determine the effect of the plants emissions on the aquatic ecosystems?
pH
In addition to a nearby mountain range, which of the following environmental conditions would be required for the process in the diagram to occur?
A cool seabreeze and a high pressure system
