Answer

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