उत्तर
Thermal Stratification is usually found in aquatic habitats. The change in the temperature profile with increasing depth in a water body is called thermal stratification. There are three kinds of thermal stratifications.
- Epilimnion – The upper layer of warmer water.
- Metalimnion – The middle layer with a zone of a gradual decrease in temperature.
- Hypolimnion – The bottom layer of colder water.
