Question

Quizplus · Accepted Answer

Thermal stratification and restriction on mixing of surface and deeper waters are most likely to occur in the summer when the sun heats up the surface water causing it to become less dense and form a warm layer that sits on top of the colder deeper water. This creates a "thermocline" which restricts mixing and can lead to separate layers of water with different temperatures and oxygen levels.
