What is stratification in lakes and reservoirs?

• A. Disruption of the water cycle
• B. Formation of separate layers of temperature, plant life, or animal life
• C. Contamination of water bodies
• D. Decrease in water clarity

Answer: (B)

Stratification in lakes and reservoirs refers to the formation of distinct layers within the water column, which can vary in temperature, plant life, or animal life. This phenomenon occurs primarily in larger bodies of water where temperature differences lead to the creation of layers. During warmer months, for example, the upper layer, known as the epilimnion, heats up due to solar radiation, while the lower layer, or hypolimnion, remains colder and denser. This separation can impact the distribution of nutrients, oxygen levels, and the types of organisms that thrive in each layer. Therefore, understanding stratification is crucial for water management, aquatic ecology, and addressing issues such as habitat diversity and water quality. The other options do not accurately describe stratification. The disruption of the water cycle relates to broader environmental processes, while contamination refers to the presence of harmful substances in water bodies. A decrease in water clarity may result from various factors, but it does not specifically pertain to the layering of water in lakes and reservoirs.
