Faulted southeastern side of Svyatoy Nos peninsula, Lake Baikal – active faulting shown by faceted spurs. Artificial rendering of the Albertine Rift showing four of its rift lakes A rift lake is a lake formed as a result of subsidence related to movement on faults within a rift zone, an area of extensional tectonics in the continental crust .
Many of the world's largest lakes are located in rift valleys. [2] Lake Baikal in Siberia, a World Heritage Site, [3] lies in an active rift valley. Baikal is both the deepest lake in the world and, with 20% of all of the liquid freshwater on earth, has the greatest volume. [4]
Mono Lake (/ ˈ m oʊ n oʊ / MOH-noh) is a saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in an endorheic basin. The lack of an outlet causes high levels of salts to accumulate in the lake which make its water alkaline .
At its height during the Last glacial period some 22,000 years ago, water filled Lake Manly to form a body of water that may have been 585 feet (178 m) deep and 90 miles (140 km) long. [33] Much smaller lakes filled parts of Death Valley during interglacials; the largest of these was 30 feet (9.1 m) deep and lasted from 5000 to 2000 years ago. [34]
[3] [7] Lakes are divided into photic and aphotic regions, the prior receiving sunlight and latter being below the depths of light penetration, making it void of photosynthetic capacity. [2] In relation to lake zonation, the pelagic and benthic zones are considered to lie within the photic region, while the profundal zone is in the aphotic ...
Lake Shala, in the East African Rift Valley. A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity.
Author and ice rescue instructor Luc Mehl reports he discovered the mysterious formations while ice skating with a friend atop Big Lake, about 60 miles north of Anchorage.
Static rejuvenation may also occur, in rare instances, when a downstream knickpoint erodes its way upstream to a lake which establishes base level for its tributaries. When the knickpoint reaches the lake, the lake drains, and the base level of upstream waters lowers rapidly from that of the (now former or shrunk) lake to that of the river ...
