air pollution
The contamination of Earth’s land, water, or air is called?
pollution.
A specific, identifiable pollution source is called a.
point source.
What is the natural pH of rain?
5.6
Liquids, chemicals, heat, light, and noise cause pollution.
true
A nonpoint source of pollution is widely spread and cannot be tied to a specific origin.
true.
What types of health problems does acid rain cause in humans?
Acid rain can cause asthma, lung damage, and bronchitis for humans
Pollution has no effect on animals or plants in the environment.
false
Oxygen is a harmful type of air pollution
false
How does acid rain harm forests?
Acid rain harms forests by seeping into the ground, dissolving nutrients
How do the characteristics of emissions from multiple urban sources complicate efforts to control air pollution in cities?
Emissions from various urban sources like vehicles, factories, and residential heating differ in composition, timing, and location, creating a complex mix that disperses unevenly. This variability complicates monitoring, regulation, and mitigation because it’s difficult to target a single source or develop uniform control strategies.
Why is pollution around big cities often called nonpoint source pollution?
Because it comes from many sources like vehicles and factories, making it hard to identify one exact origin.
How does acid rain damage buildings and objects?
Acid rain causes damage to buildings or other objects by causing deterioration to certain materials.
Why is it challenging to attribute specific health impacts to individual pollutants in urban air pollution?
Urban air pollution is a complex mixture of gases and particles from numerous sources that interact chemically in the atmosphere. This makes it difficult to isolate the effects of any one pollutant on health, as combined exposure and secondary pollutants can have synergistic or additive effects.
Why is urban air pollution typically classified as nonpoint source pollution rather than originating from a single point source?
Because urban air pollution arises from a diverse range of dispersed sources—such as transportation, industrial activities, and residential emissions— it is difficult to isolate a single, identifiable origin.
Acid rain is caused by chemicals released into the air from burning fossil fuels like coal and gasoline.
