Visibility can be affected by levels of air pollution and

The physical interaction of light with particles and gases in the atmosphere

Explanation:

The way visibilty works is that light bounces off objects and molecules which return to our eyes and give us the ability to see our surrondings and light in the atmosphere is scattered which at times prevents us from being able to see.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
