Impact on the Atmosphere

The contamination of air by harmful substances:

• air pollution

• photochemical smog

• reclamation

• condensation

Forms when nitrogen and carbon compounds in the air react in sunlight:

• thermal smog
• ozone layer
• acid rain
• photochemical smog

What is one benefit provided by ozone?

• Close to Earth's surface, it makes the air easier to breathe.

• Close to Earth's surface, it makes the air harder to breathe.

• High in the atmosphere, it blocks harmful UV from the Sun.

• High in the atmosphere, it forms smog.

How is ozone harmful?

• Close to Earth's surface, it is a major component of smog.

• Close to Earth's surface, it makes it easier to breathe.

• In the upper atmosphere, it blocks helpful UV rays.

• In the upper atmosphere, it forms smog.

How is ozone in the upper atmosphere destroyed?

• Chemical reactions with CFCs

• Biological processes
• burning fossil fuels

• Nuclear reactions

The mix of solid and liquid particles in the atmosphere:

• acid rain

• smog

• vapors
• particulate matter

How are particles added to the air?

• volcanic eruptions

• forest fires

• precipitation

• burning fossil fuels

Rain or snow that has a lower pH than that of normal rainwater:

• acid precipitation

• toxic precipitation

• basic precipitation

• sour precipitation

What is the main cause of acid precipitation?

• ozone

• burning fossil fuels

• organisms breathing

• mining operations

How can individuals help keep air clean?

• reduce energy use

• use renewable energy sources

• use public transportation

• add ozone by burning more fossil fuels
