APES - Unit 7 Study Guide

the data that were used to create this graph were collected in the winter. Which of the following best describes how the graph would be different if the data were collected in the middle of the summer?

. Concentrations for component would be higher throughout the graph

most likely account for the levels of of indoor air pollution in India and sub Saharan Africa, as shown in the graph

. Use of biomass fuel sources such as wood and charcoal for cooking

A paper company located on the banks of a river discharges its treated wastewater into the river. what would be the best control group to evaluate the treated wastewater from the paper company?

A sample of waterupstream from the same river

it best explains why a thermal inversion tends to concentrate pollutants in the air layer closest to the Earth's surface.

Based on the layers in the diagram, the air layer closest to the Earth's surface is denser than the layer above

best location to obtain a water sample from to determine if the paper plant is affecting the acidity of the river.

Immediately downstream from the paper plant

conclusions can be drawn from the data presented in the graph.

In moderately developed regions such as China and Latin America, an individual's health is more or as likely to be affected by urban outdoor pollution than by indoor pollution

conclusions can best be drawn from the data in the graph.

Location A has the greatest need for remediation because the radon levels in the building are the highest and exceed the action level.

Canada has proposed an action plan to address climate change and air pollution. The action plan will reduce the impact of greenhouse gases and pollutants on the environment and human health.

The plan supports phasing out traditional coal power plants and transitioning to sources like hydroelectricity, wind, and solar power.

best explains the cause of the trend shown in the graph for lead emissions in the United States from 1970 to 2011.

Unleaded gasoline was first introduced in 1974, and amendments to the Clean Air Act required cars with the model year 1975 or later to use only unleaded gasoline

which of the following sources should be examined in a study to determine the impact of a geologic source on levels of in the atmosphere

Volcanoes

Scientists have observed that the health of people living in moderately developed regions, which have developed transportation and industry but lack environmental control measures, is more likely to be

affected by urban outdoor pollution than by indoor air pollution.

which of the following would be the most effective plan for the manage to propose to the city

install catalytic converters at the plant

which of the following best describes why the authors claim that reducing noise exposure is currently more of a public policy problem than a scientific problem?

most public health impacts of noise were already identified in the 1960s

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment that contains soil, leaf debris, an earthworm, heterotrophic bacteria, and a sun lamp.

no representation of photosynthesis in the model environment

Scientists have been monitoring the atmosphere from Mauna Loa in Hawaii since 1958, which of the following is used by scientists to measure in the atmosphere.

parts per million

Which of the following water quality indicators should be measured to best determine if the wastewater is increasing the acidity of the water?

the amount of hydrogen ions

which of the following best describes why the authors claim that noise exposure will be a major health problem in the twenty - first century

there is sufficient evidence to support that noise exposure negatively impacts the immune system

If the air layers in the diagram were relabeled to illustrate normal atmospheric conditions, the correct labeling from the air layer closest to the Earth's surface to the one farthest from the Earth's surface would be

warm air, cool air, cooler air.

The graph below depicts the various components of smog for a densely populated urban area in the Northern Hemisphere. Each plotted line ( A,B C,D ) is a different component of smog.

● Curve C

which of the following best describes why the authors do not claim that noise exposure induces birth defects in humans?

● There is insufficient evidence to support that noise exposure induces birth defects in humans and the authors does not claim that noise exposure induces birth defects in humans.
