Air Pollution

What are common sources of air pollution?

• Vehicle emissions

• Household cleaning products

• Plastic waste

• Agricultural fertilizers

What is a catalytic converter?

• A device that increases fuel efficiency in vehicles.

• A device in vehicles that reduces harmful emissions by converting them into less harmful substances.

• A type of exhaust system that enhances engine performance.

• A component that filters out noise from the engine.

What are greenhouse gases?

• Gases that cool the atmosphere and reduce global warming.

• Gases that trap heat in the atmosphere, contributing to global warming and climate change.

• Gases that are released during photosynthesis and help plants grow.

• Gases that are found only in urban areas and have no effect on climate.

What is the significance of air quality indices (AQI)?

• They measure temperature variations in the atmosphere.

• They provide a standardized way to report and communicate air quality levels to the public.

• They are used to predict weather patterns.

• They indicate the levels of humidity in the air.

What is smog?

• A type of air pollution that is a mixture of smoke and fog, often exacerbated by industrial emissions and vehicle exhaust.

• A weather phenomenon characterized by heavy rainfall and thunderstorms.

• A type of fog that occurs only in coastal areas.

• A form of air pollution that consists solely of smoke from wildfires.

What is air pollution?

• The presence of harmful substances in the atmosphere that can affect health and the environment.

• A natural phenomenon that occurs in clean air.

• The absence of any pollutants in the atmosphere.

• A type of weather condition that affects air quality.

What is radon and where is it commonly found?

• A colorless, odorless gas that can accumulate in homes, particularly in basements, and is a health hazard.

• A type of mineral found in rocks and soil that is harmless to humans.

• A liquid chemical used in refrigeration systems that is safe to breathe.

• A radioactive metal commonly used in construction materials.

What is the Montreal Protocol?

• An international treaty to promote renewable energy sources.

• An international treaty designed to phase out substances that deplete the ozone layer.

• A local agreement to reduce air pollution in cities.

• A global initiative to increase carbon emissions.

What is the difference between 'good' ozone and 'bad' ozone?

• 'Good' ozone is found in the troposphere and protects against UV radiation.

• 'Good' ozone is found in the stratosphere and protects against UV radiation, while 'bad' ozone is found at ground level and is a harmful pollutant.

• 'Bad' ozone is found in the stratosphere and is beneficial for health.

• 'Bad' ozone is found at ground level and is a harmless gas.

What is the role of the ozone layer?

• It provides oxygen for breathing.

• It protects living organisms by absorbing the majority of the sun's harmful ultraviolet (UV) radiation.

• It regulates the Earth's temperature.

• It helps in the formation of clouds.
