Lakes lying in granite basins, such as those in the northeastern U.S., tend to become acidified by acid rain more readily than lakes lying in limestone basins, such as those found in the midwestern U.S. Why is this so?
A) The granite contains acidic minerals that dissolve in the rain water and are added to the lakes.
B) Since the acidified water cannot percolate through the granite, the acid in the lakes becomes more concentrated.
C) The limestone, which is calcium carbonate, serves to neutralize the acid in the rain.
D) There is more acid rain in the northeast than in the midwestern regions of the U.S.
