Multiple choice

What is the primary source of Sulfur Dioxide (SO2) emissions?

  1. Transportation

  2. Industrial Activities

  3. Residential Heating

  4. Natural Sources
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Industrial activities, particularly those involving fossil fuel combustion, are the major source of SO2 emissions.

Multiple choice

How does Sulfur Dioxide contribute to acid rain?

  1. Reacts with water vapor to form sulfuric acid

  2. Neutralizes alkaline compounds in the atmosphere

  3. Increases the pH of rainwater

  4. Decreases the acidity of soil
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

SO2 reacts with water vapor in the atmosphere to form sulfuric acid, which contributes to acid rain.

Multiple choice

What is the primary method for controlling Sulfur Dioxide emissions from power plants?

  1. Carbon Capture and Storage

  2. Wind Turbines

  3. Solar Panels

  4. Flue Gas Desulfurization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Flue gas desulfurization (FGD) systems are commonly used to remove SO2 from the exhaust gases of power plants.

Multiple choice

Which of the following is NOT a common industrial process that emits Sulfur Dioxide?

  1. Metal Smelting

  2. Petroleum Refining

  3. Paper and Pulp Production

  4. Food Processing
Reveal answer Fill a bubble to check yourself

Explanation

Food processing is generally not a significant source of SO2 emissions compared to other industrial activities.

Multiple choice

How does Sulfur Dioxide affect visibility?

  1. Increases visibility by scattering light

  2. Decreases visibility by absorbing light

  3. Has no effect on visibility

  4. Improves visibility by reducing haze
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

SO2 absorbs light in the visible spectrum, reducing visibility and contributing to haze.

Multiple choice

What type of air pollution is caused by the burning of fossil fuels, such as coal and oil?

  1. Photochemical smog

  2. Acid rain

  3. Particulate matter

  4. Indoor air pollution
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acid rain is primarily caused by the emission of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, which react with water vapor in the atmosphere to form acids.
