Question

Quizplus · Accepted Answer

In lakes situated in temperate climates, turnovers occur in spring and fall. In the spring, the surface ice melts, which causes the upper layer of the water to warm and become less dense. As the temperature of the water in the lower layers is still cold, and thus denser, the layers do not mix, resulting in a turnover. In the fall, as the temperature of the water cools, the upper layers become colder and denser, leading to another turnover.
