Consider a lake that is uniformly 10°C. What happens to the oxygen-rich surface water as it cools down to  ?

Quizplus · Accepted Answer

As water cools down, it contracts and becomes more dense. This means that the colder water will sink towards the bottom of the lake while the warmer water will stay at the surface. In this case, the oxygen-rich surface water will cool and become more dense, causing it to sink towards the bottom of the lake. This is an example of how temperature can affect the vertical distribution of oxygen in a body of water.
