What is the middle zone of a lake?


What is the middle zone of a lake? Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.


What is the bottom layer of a lake called?

Hypolimnion: The colder, dense, deep water layer in a thermally stratified lake, lying below the metalimnion and removed from surface influences.


What is the zone in the middle of a lake called?

In freshwater ecosystems The three primary zones of a lake are the littoral zone, the open-water (also called the photic or limnetic) zone, and the deep-water (also called the aphotic or profundal) zone.


What is the lowest zone of a lake?

The Benthic Zone is the bottom of the pond or lake and consists of organic sediments and soil. As the body of water ages, this zone will increase. It is considered the pond or lake's digestive system. This zone is where bacteria decompose organic matter from dead algae, aquatic plants, and fish and animal waste.

What are the layers of a lake?

Lakes have layers
  • Epilimnion. This is the upper, less dense layer of warmer water, that is readily mixed by wind. ...
  • Metalimnion. Also called the thermocline, this is the middle layer characterized by a steady drop in water temperature, that prevents water mixing between the epilimnion and hypolimnion. ...
  • Hypolimnion.


What is the structure of a lake?

A lake's shallowest layer is the epilimnion. Its middle layer is the metalimnion, or thermocline. The deepest layer is the hypolimnion. The most important chemicals in a lake are nitrogen and phosphorus.


What do you call the land that meets a lake?

A shore, on the other hand, may refer to parts of land adjoining any large body of water, including oceans (sea shore) and lakes (lake shore).
