What's in the air you breathe? | Amy Hrdina and Jesse Kroll

The video explores the composition of Earth's atmosphere, highlighting the major components like nitrogen, oxygen, and argon. It delves into the presence of pollutants, both natural and man-made, and their impact on health and the environment. The transformation of these pollutants into more harmful secondary pollutants is discussed, with examples like sulfurous and photochemical smog. The video concludes with a look at countermeasures, such as catalytic converters and regional regulations, to combat air pollution and emphasizes the need for tailored solutions to address local pollution issues.

What percentage of Earth's atmosphere is made up of nitrogen?

• 0.93%

• 0.07%

• 21%

• 78%

Which gas is formed from the radioactive decay of potassium?

• Argon

• Methane

• Nitrogen

• Oxygen

What is a primary pollutant?

• A compound formed by natural processes

• A toxic compound directly emitted from a source

• A compound that forms secondary pollutants

• A harmless compound in the atmosphere

How do natural oxidants affect pollutants?

• They make pollutants harmless

• They break down pollutants, sometimes creating more toxic substances

• They have no effect on pollutants

• They increase the concentration of pollutants

What is a characteristic of sulfurous smog?

• It is only found in rural areas

• It impairs visibility and causes lung damage

• It improves air quality

• It is beneficial for plant growth

What is one measure taken to reduce vehicle emissions?

• Encouraging more car usage

• Increasing the use of coal

• Installing catalytic converters

• Promoting wood burning

Why is there no universal solution to air pollution?

• Pollution cannot be controlled

• All regions have the same pollution problems

• Different regions have unique pollutants

• Pollution is not a serious issue
