When the upper epilimnion waters become cooler than the hypolimnion waters, and the surface water sinks while the deeper water rises is known as
A) intertidal zonation.
B) upwelling.
C) pelagic division.
D) overturn.
E) eutrophication.
Epilimnion
The epilimnion is the upper layer of water in a stratified lake, characterized by warmer temperatures and high levels of oxygen.
Hypolimnion
The colder, bottom layer of water in a stratified lake, lying below the warmer epilimnion.
Overturn
To upset or reverse a decision, situation, or setup, often dramatically.
- Comprehend seasonal and depth-related changes in aquatic environments, such as lake stratification and turnover.

Final Answer :
D
Explanation :
The process described in the question is known as lake overturn, which occurs when the temperature of the upper epilimnion waters become cooler than the hypolimnion waters during the autumnal cooling. This results in the surface water sinking and the deeper water rising, causing a mixing of the different water layers in a lake.
