Question
Which is NOT caused by acid rain?
- Damage to statues
- Dying fish
- Spread of disease
- Weakened trees
Hint:
Acid rain has nothing to do with spreading of diseases.
The correct answer is: Spread of disease
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Acid rain damages statues, due to lowering of water pH fishes die, and trees weakened.
