The major acid resulting from industrial sources, particularly from the combustion of fossil fuels, is sulfuric acid. This acid is formed when sulfur dioxide (SO2) is released into the atmosphere and reacts with water vapor.

Stratospheric ozone destruction involves a complex series of reactions that begin with UV from sunlight causing Cl atoms to break free from CFCs.

When chlorofluorocarbons (CFCs) are released into the atmosphere, they eventually reach the stratosphere, where ultraviolet (UV) radiation breaks them down, releasing chlorine atoms. These chlorine atoms then participate in reactions that lead to the destruction of ozone (O3)

The health problem associated with UV exposure that is also linked to the thinning of Earth's ozone layer is skin cancer. The ozone layer helps to block harmful ultraviolet (UV) radiation from the sun, and its depletion allows more UV radiation to reach the Earth's surface, increasing the risk of skin cancer and other UV-related health issues.

Stratospheric ozone depletion is currently most serious over New Zealand and Australia.

CFCs (chlorofluorocarbons) were primarily used in refrigeration and aerosols. They were commonly used as refrigerants in cooling systems and as propellants in aerosol sprays.

A temperature inversion around a large city such as Los Angeles traps pollutants in cold air near the ground. During a temperature inversion, a layer of warm air sits above cooler air at the surface, preventing the cooler air (and the pollutants within it) from rising and dispersing.

The Donora killer smog of 1948 was primarily a consequence of emissions from the steel mill. The smog was exacerbated by meteorological conditions, such as temperature inversions, which trapped pollutants in the valley where Donora, Pennsylvania, is located.

Acid rain is an example of wet deposition.

Primary pollutants are chemicals or particles that are directly emitted from identifiable sources.

Ozone is a secondary air pollutant. It is formed in the atmosphere through chemical reactions between primary pollutants (such as volatile organic compounds and nitrogen oxides) in the presence of sunlight. The other substances listed (mercury, sulfur dioxide, carbon monoxide, and chlorofluorocarbons) are considered primary pollutants, as they are directly emitted into the air from various sources.

Air pollution is best defined as gases or particles present in high enough concentrations in the atmosphere to harm humans, other organisms and structures.

The correct answer is The Chlorine Radical.

Chlorine radicals are highly reactive species that can catalytically destroy ozone in the stratosphere. They are released from chlorofluorocarbons (CFCs) when they are broken down by ultraviolet (UV) radiation. While CFCs are the source of chlorine radicals, it is the chlorine radicals themselves that are directly responsible for the catalytic destruction

The ozone hole is the largest over Antarctica. This phenomenon occurs primarily during the Southern Hemisphere's spring (September to November) when conditions in the stratosphere lead to significant depletion of ozone due to the presence of chlorine and bromine compounds, which are released from man-made chemicals like chlorofluorocarbons (CFCs).

The correct answer is:

d. It helps save a manager time in understanding the data in a graphic.

A talking title is designed to provide a clear and concise summary of the graphic's content, making it easier for viewers, such as managers, to quickly grasp the key message without needing to analyze the graphic in detail.

a. True

When preparing a table or visual that incorporates information from multiple sources, it is generally recommended not to use superscripts to indicate sources, as this can lead to confusion. Instead, it's better to provide a clear citation or reference list that indicates all sources used.

A map is most helpful for showing c. geographic relationships.

b. False

In line charts, the vertical (quantity) increments do not have to be the same as the horizontal (time) increments. The key is to accurately represent the data and maintain the correct relationships between the values. Different increments can be used as long as the scale is clear and the data is presented accurately.

To make the pie chart easy to understand, Allen should c. explode the slices that need to be emphasized. This technique helps to visually highlight the differences between the slices, making it clearer which portions of the expenditure are more significant, such as the lower administrative overhead compared to youth services.

a. True

In this scenario, b. a segmented bar chart will best represent the data. A segmented bar chart (also known as a stacked bar chart) allows you to show the total sales for each year while also breaking down the contributions of the different age categories, making it easy to compare both the total and the individual segments.

The guideline that ensures the effective use of graphics is:

c. Use graphics to contribute to the overall understanding of the idea under discussion.

This option emphasizes the importance of using graphics to enhance comprehension and support the message being conveyed.

a. True

The true statement about the use of graphics is:

d. A few pages of graphics can effectively convey several hundred pages of text.

Graphics can often summarize complex information and present it in a more digestible format, making it easier for the audience to understand key points quickly.
