What is thermal expansion?

Text Solution

Verified by Experts

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.
