What are the layers of a lake called?
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 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.
How do different types of lakes form?
Lakes may also be created by landslides or mudslides that send soil, rock, or mud sliding down hills and mountains. The debris piles up in natural dams that can block the flow of a stream, forming a lake. Dams that beavers build out of tree branches can plug up rivers or streams and make large ponds or marshes.

What keeps water in a lake?
Most lakes are fed by springs, and both fed and drained by creeks and rivers, but some lakes are endorheic without any outflow, while volcanic lakes are filled directly by precipitation runoffs and do not have any inflow streams.
What is unique about lakes?
Salty or fresh, lakes are some of the only freely available water sources on land. Aside from rivers and streams, the rest of the world's freshwater is locked up in ice or trapped underground.
How big is a pond before it becomes a lake?
The definition of lakes and why there's no standardization A pond is a body of water less than 0.5 acres (150 square meters) in an area or less than 20 feet (6 meters) in depth. A lake is defined as a body of water bigger than 1 acre (4,000 m²), although size is not a reliable indicator of its water quality.
What are the basic characteristics of a lake?
lake, Relatively large body of slow-moving or standing water that occupies an inland basin. Lakes are most abundant in high northern latitudes and in mountain regions, particularly those that were covered by glaciers in recent geologic times.
How deep are lakes usually?
A small pond is usually 4 to 20 feet deep, while lakes are typically any depth beyond 20 feet. In most lakes, the deepest spot is known as the “last drop” or “end of the lake.” The water in a small pond or a natural spring will not have any depth to it.
Do all lakes lead to the ocean?
Exorheic, or open lakes drain into a river, or other body of water that ultimately drains into the ocean. Endorheic basins fall into the category of endorheic or closed lakes, wherein waters do not drain into the ocean, but are reduced by evaporation, and/or drain into the ground.
