Question

Which of the following explains why the Midwest is not suffering as severe damage from acid rain as are the northeastern states?
a. Midwest has few sources of acid rain-forming pollutants
b. pH of rainfall in Midwest is significantly higher than that in the Northeast
c. soils in the Midwest have a higher buffering capacity than do those in the Northeast
d. soils in the Midwest have a lower buffering capacity than do those in the Northeast
e. Midwestern soils have lower concentrations of toxic metals to be leached into watersheds

Explanation / Answer

Answer : c. soils in the Midwest have a higher buffering capacity than do those in the Northeast.

Many air polluting industries and power producers are in the Midwest and Ontario regions of North America. But Midwest is not suffering as severe damage from acid rain as are the northeastern states which has less industries. Because soil with high buffering capacity can neutralize the acid rain but the soil with low buffering capacity can make the soil acidic.
