Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

All of the above factors can affect air quality resilience. The type of air pollution can determine the severity of the effects on the ecosystem. The concentration of air pollution can determine the extent of the damage. The duration of air pollution can determine the length of time it takes for the ecosystem to recover. The sensitivity of the ecosystem to air pollution can determine how easily it is damaged by air pollution.

Multiple choice

What are some examples of air quality resilience?

  1. The ability of a forest to recover from a wildfire.

  2. The ability of a wetland to absorb and break down pollutants.

  3. The ability of a city to adapt to the effects of air pollution.

  4. All of the above.

D Correct answer
Explanation

All of the above are examples of air quality resilience. A forest's ability to recover from a wildfire is an example of the ecosystem's ability to recover from air pollution. A wetland's ability to absorb and break down pollutants is an example of the ecosystem's ability to absorb and break down pollutants. A city's ability to adapt to the effects of air pollution is an example of the community's ability to adapt to the effects of air pollution.

Multiple choice

What is the primary source of air pollution in urban areas?

  1. Industrial emissions

  2. Vehicle exhaust

  3. Agricultural activities

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

Vehicle exhaust, particularly from diesel engines, is a major contributor to air pollution in urban areas due to the release of harmful pollutants such as particulate matter, nitrogen oxides, and hydrocarbons.

Multiple choice

Which of the following is a major cause of air pollution in rural areas?
