All Flashcards
Dry deposition formation?
NOx and SO2 released, react with ammonia, form nitric salts and sulfates.
Wet deposition (acid rain) formation?
NOx and SO2 react with water, create nitric and sulfuric acid.
How does cleaner fuel reduce acid rain?
Reduces SO2 and NOx emissions.
How does increased fossil fuel efficiency help?
Reduces the amount of fossil fuels burned.
How does renewable energy reduce acid rain?
Doesn't produce SO2 or NOx.
How do trees help mitigate acid rain?
Absorb CO2 and can help neutralize acids.
How do scrubbers reduce acid rain?
Remove SO2 from power plant emissions.
How does using natural gas help reduce acid rain?
It produces less SO2 and NOx than coal when burned.
How do emission limits reduce acid rain?
By restricting the amount of SO2 and NOx that can be released.
Define Acid Deposition.
Acids falling from the atmosphere to Earth's surface.
Define Acid Precipitation.
Acidic rain, snow, or fog.
What is Nitric Acid (HNO3)?
A strong acid formed from nitrogen oxides.
What is Sulfuric Acid (H2SO4)?
A strong acid formed from sulfur dioxide.
What are Nitric Salts?
Compounds formed when nitrogen oxides react in the atmosphere.
What are Sulfates?
Compounds formed when sulfur dioxide reacts in the atmosphere.
What is Acidification?
The process of becoming more acidic.
Define Dry Deposition.
NOx and SO2 pollutants falling as gas, particulate, or aerosol.
Define Wet Deposition.
NOx and SO2 forming acids that dissolve in precipitation.
