APES Unit 7: Air Pollution Test

What is the significance of the Air Quality Index (AQI)?

• It provides information on air quality and associated health effects.

• It measures the temperature of the air.

• It indicates the level of humidity in the atmosphere.

• It tracks the amount of carbon dioxide in the air.

How do nitrogen oxides contribute to air pollution?

• They react with VOCs in the presence of sunlight to form ground-level ozone.

• They directly emit harmful particles into the atmosphere.

• They absorb carbon dioxide and reduce greenhouse gases.

• They increase the acidity of rainwater.

What is the difference between stratospheric and tropospheric ozone?

• Stratospheric ozone is a harmful air pollutant; tropospheric ozone protects against UV radiation.

• Stratospheric ozone protects against UV radiation; tropospheric ozone is a harmful air pollutant.

• Stratospheric ozone is found at ground level; tropospheric ozone is found in the upper atmosphere.

• Stratospheric ozone is produced by human activities; tropospheric ozone occurs naturally.

What is smog?

• A type of air pollution that is a mixture of smoke and fog, often exacerbated by ground-level ozone.

• A weather phenomenon characterized by heavy rainfall and thunderstorms.

• A type of fog that occurs in coastal areas due to high humidity.

• A form of air pollution caused solely by vehicle emissions.

What is particulate matter?

• A mixture of tiny solid particles and liquid droplets in the air that can affect health.

• A type of gas that is harmful to the environment.

• A solid substance that does not dissolve in water.

• A liquid that is used for cleaning purposes.

What are volatile organic compounds (VOCs)?

• Organic chemicals that can evaporate into the air and contribute to air pollution.

• Inorganic substances that are solid at room temperature.

• Gases that are always harmful to human health.

• Compounds that do not evaporate and are used in construction.

What are some strategies to reduce air pollution?

• Using public transportation, reducing vehicle emissions, and promoting renewable energy.

• Increasing the use of fossil fuels for energy production.

• Encouraging more private vehicle ownership.

• Limiting the use of electric vehicles.

What are the health effects of air pollution?

• Respiratory issues, cardiovascular diseases, and aggravated asthma.

• Improved lung function and better cardiovascular health.

• Increased energy levels and enhanced mood.

• No significant health effects observed.

Which type of ozone is considered an air pollutant?

• Stratospheric ozone

• Tropospheric ozone

• Ozone in the upper atmosphere

• Ozone in the stratosphere

What are some sources of particulate matter?

• Burning wood, dust from gravel roads, volcanoes, forest fires.

• Industrial emissions, car exhaust, and household cleaning products.

• Ocean waves, sunlight, and humidity.

• Plastic waste, electronic waste, and food waste.
