Lake stratification
From Wikipedia, the free encyclopedia
Lake stratification is the separation of lakes into three layers:
- Epilimnion - top of the lake.
- Metalimnion (or Thermocline) - middle layer that may change depth throughout the day.
- Hypolimnion - the bottom layer.
The thermal stratification of lakes is a change in the temperature at different depths in the lake. Temperatures change from season to season to create a cyclic pattern that is repeated from year to year.
If the stratification of water lasts for extended periods, the lake is meromictic.
