Question

Quizplus · Accepted Answer

The hypolimnion of a lake is the layer of water below the thermocline, which separates the epilimnion and hypolimnion. This layer is cool because it does not mix with the warmer surface water in the epilimnion. Therefore, choice C is the correct answer. The other options are not accurate because the hypolimnion is denser, not less dense, than the epilimnion, and it is typically less oxygenated due to the lack of photosynthesis and circulation.
