Why has acidic precipitation been particularly devastating to rivers and lakes in certain regions, such as the northeastern United States, Canada, and Scandinavia?
A) Waters there are oligotrophic and thus lack bases to buffer acid inputs.
B) Waters there are anoxic and thus lack free radicals to inactivate acid inputs.
C) Waters there are colder and thus chemical inactivation of acids proceeds slowly.
D) Waters there harbor populations of aquatic organisms that are unusually sensitive to acidity.
Ans: A) Waters there are oligotrophic and thus lack bases to buffer acid inputs.
