Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Key examples include carbon dioxide, methane, and water vapor.

Front

What are sources of particulate matter?

Back

Sources of particulate matter include burning wood, dust from gravel roads, volcanoes, and forest fires.

Front

What is the function of scrubbers in industrial settings?

Back

Scrubbers are used on factory stacks to remove gases and particulate matter from emissions.

Front

What pollutants do catalytic converters reduce in car exhaust?

Back

Catalytic converters reduce carbon monoxide and hydrocarbons in car exhaust.

Front

What is the role of stratospheric ozone?

Back

Stratospheric ozone prevents harmful UV radiation from reaching the Earth's surface.

Front

Define air pollution.

Back

Air pollution is the presence of harmful substances in the atmosphere, which can affect human health and the environment.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

List three major sources of carbon dioxide emissions.

Back

Major sources of carbon dioxide emissions include fossil fuel combustion, deforestation, and industrial processes.

Front

What is particulate matter (PM)?

Back

Particulate matter (PM) refers to tiny solid or liquid particles suspended in the air, which can be harmful to health when inhaled.

Front

Explain the difference between tropospheric and stratospheric ozone.

Back

Tropospheric ozone is a harmful pollutant at ground level, while stratospheric ozone protects life on Earth by absorbing UV radiation.
