All Flashcards
Effect of acid rain on plants?
Leaf damage, reduced photosynthesis, stunted growth.
Effect of acid rain on soils?
Lowered pH, dissolved nutrients, release of toxic metals.
Effect of acid rain on aquatic ecosystems?
Acidification of water bodies, harm to aquatic life.
Effect of acid rain on infrastructure?
Erosion of statues and gravestones.
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.
What are the steps in wet deposition?
- NOx and SO2 released. 2. React with water. 3. Form nitric and sulfuric acid. 4. Acid precipitation falls.
Describe the process of dry deposition.
- NOx and SO2 released. 2. React with ammonia. 3. Form nitric salts and sulfates. 4. Fall as gas/particulate.
What is the process of acidification of lakes?
- Acid rain falls. 2. pH of water decreases. 3. Aluminum released from soils. 4. Harm to aquatic life.
