Quizplus · Accepted Answer

The subsurface layer of water in a stratified lake in summer, characterized by a steep and rapid decline in temperature with depth, is called the metalimnion. This layer is also known as the thermocline because it is the boundary between the warm, well-lit epilimnion and the cold, dark hypolimnion. It is often the location of the most active biological activity and serves as an important habitat for fish and other aquatic organisms.
