What is the significance of stratification in lakes ?

Explanation

Temperature variations occur with seasonal changes temperature regions. These differences in the temperature form thermal layers in water. These phenomena are called thermal stratification.
During autumn (also called fall), the epilimnion cools down and the surface water becomes (Spring heavy when the temperature iş `4^(@)C` and sinks to the bottom of the lake. Overturns bring about .uniform temperature in lakes during that period. This circulation during the autumn is known as the fall or autumn overturn. The upper oxygen rich water S Epilimnion reaches the hypolimnion and the nutrient rich Thermocline bottom water comes to the surface. Thus there is Autumn uniform distribution of nutrients and oxygen in the Hypolimnion Jake. In spring season the temperatures start rising Stratification in temperate lakes when it reaches `4^(@)C,` the water becomes more dense and heavy and sinks to the bottom, taking oxygen rich water to the bottom. The upper oxygen rich water sinks down and bottom nutrient rich water reaches the surface.
