Question

Quizplus · Accepted Answer

The mixing of oxygenated water with nutrient-laden water that occurs in lakes is called fall overturn. Fall overturn occurs when the surface water becomes colder and denser due to the decrease in temperature, causing the water to sink to the bottom of the lake. As the water sinks, it mixes with the nutrient-rich water at the bottom, allowing oxygen to be distributed throughout the lake.
