Question

Quizplus · Accepted Answer

Lakes are often more vulnerable than streams to contamination due to their slower flushing rate and longer residence time of water. Pollutants can accumulate and persist in lakes, leading to harmful impacts on aquatic life and human health.

Note: A is incorrect because stratified layers of lakes are characterized by little to no vertical mixing, creating a barrier that can trap pollutants in deeper layers. B, D, and E are also incorrect because they do not accurately depict the characteristics of lakes compared to rivers and streams.
