Question

which is a potential cause of high turbidity found in a north carolina stream?
a. soil erosion
b. acid rain
c. cold weather

Explanation:

Turbidity in a stream is related to the presence of suspended particles. Soil erosion (A) can introduce soil particles into the stream, increasing turbidity. Acid rain (B) affects water chemistry more than turbidity directly, and cold weather (C) doesn't typically cause high turbidity. So soil erosion is a potential cause.

Answer:

A. soil erosion
