What is an endorheic rift lake?
An endorheic lake (also called a sink lake or terminal lake) is a collection of water within an endorheic basin, or sink, with no evident outlet. Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation.
How do endorheic lakes form?
Endorheic lakes form when endorheic basins fill with water from surrounding streams or local rains. Well-known examples include the Great Salt Lake and the Caspian Sea, the latter being the largest lake on Earth. If inflow exceeds seepage and evaporation, the lake grows.
What is a basin in a lake?
Definition of lake basin 1 : the depression occupied by a lake. 2 : the area from which drainage reaches a lake.
Why are endorheic basins sensitive to environmental changes?
Since the main outflow pathways of these lakes are chiefly through evaporation and seepage, endorheic lakes are usually more sensitive to environmental pollutant inputs than water bodies that have access to oceans, as pollution can be trapped in them and accumulate over time.
What is the difference between lake and basin?
A lake usually has water in it unless it’s a dry lake. A basin is simply a lower piece of ground and sometimes also collects water but not enough to be thought of as a lake.
Why are basins important?
Basins are vital to human existence, since they provide clean water for drinking; water for growing food; and water to nourish plant life, which provides the oxygen people breathe. Historically, basins were also an important factor in determining geopolitical borders.
Is lake Victoria endorheic?
There are endorheic lakes in Antarctica in the McMurdo Dry Valleys, Victoria Land, the largest ice-free area in Antarctica.
Is Lake Tahoe endorheic?
Lake Tahoe is unique in that it is endorheic basin. This means that it drains into the Truckee River and instead of flowing toward the ocean as most rivers do, it flows east into the mountains with a final destination in Pyramid Lake.
What is the definition of basin landform?
A basin landform consists of an area of land, usually like a smaller prairie, enclosed by higher land such as hills and mountains.
What is the meaning of endorheic lake?
An endorheic lake (also called a sink lake or terminal lake) is a collection of water within an endorheic basin, or sink, with no evident outlet. Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation.
What is an endorheic body of water?
Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world’s largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic.
Which of the following is remnant of an endorheic basin?
The Great Salt Lake in Utah is remnant of an endorheic basin. Endorheic basins and lakes are often saline, and can form salt lakes or dried salt pans over time. Australia holds the largest concentration of endorheic basins and lakes of any continent on Earth. Caspian Sea, the world’s largest lake, is actually endorheic.
How do endorheic lakes accumulate water?
The two main ways that endorheic lakes accumulate water are through river flow into the lake (discharge) and precipitation falling into the lake. The collected water of the lake, instead of discharging, can only be lost due to either evapotranspiration or percolation (water sinking underground, e.g., to become groundwater in an aquifer ).
