Process: - Acid rain flows through soil - Chemicals from the acid rain kill plants and trees - The acid rainwater flows into rivers and streams - The chemicals kill fish - The chemicals kill animals that drink the water - Nitrogen builds up - Nitrogen destroys fish and shellfish populations. Question: suppose Less chemicals soaked in the soil happens, how will it affect MORE damage by acid rain. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
----
Answer: less

Process: - Water comes into contact with something made of iron - The water combines with carbon dioxide in the air to form carbonic acid - As the acid is formed, the iron starts to dissolve - Some of the water breaks down into hydrogen and oxygen - The free oxygen and dissolved iron bond together - They form iron oxide, which is rust - Question: suppose lower the heat happens, how will it affect the iron will dissolve slower. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
----
Answer: no effect

Process: - Coal is burned - Sulfur in the coal combines with oxygen to form sulfur oxides - The sulfur oxides are released into the atmosphere - The sulfides combine with oxygen in the atmosphere to form sulfur trioxide - The sulfur trioxide reacts with water in the atmosphere to form sulfuric acid, a very strong acid - The sulfuric acid makes the rain acidic - Question: suppose more coal is burned happens, how will it affect less sulfuric acid is formed. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
