This diagram shows pH ranges from 0 to 14, with 7 being neutral, less than 7 as acidic, and greater than 7 being alkaline (basic). How does pollution affect the pH of a stream? A. When the acid rain finds its way into the stream, the pH in the stream can increase.
B. When the acid rain finds its way into the stream, the pH in the stream can decrease.
C. Pollution corresponds with decreased photosynthesis, which may cause long-term stability in pH.
