What is the area of a lake closest to the shore called?
What is the area of a lake closest to the shore called? Littoral Zone This zone is the shore area of the lake or pond. It consists of the area from dry land that slopes into the open water and can be very narrow or very wide. Typically, oligotrophic, or young, bodies of water have narrow Littoral Zones due to their steep sides.
What are the parts of a lake?
Limnology divides lakes into three zones: the littoral zone, a sloped area close to land; the photic or open-water zone, where sunlight is abundant; and the deep-water profundal or benthic zone, where little sunlight can reach.
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 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 3 zones of a lake?

What are the 4 zones of a lake?
So, the four zones of a lake are: the nearshore or littoral zone, open water or limnetic zone, deep water or profundal zone, the benthic zone or lake floor. The different conditions, such as the amount of light, food, and oxygen in each of the lake zones, affect what kind of organisms live there.
Is the land around a lake called a beach?
A beach is a narrow, gently sloping strip of land that lies along the edge of an ocean, lake, or river. Materials such as sand, pebbles, rocks, and seashell fragments cover beaches. Most beach materials are the products of weathering and erosion.
