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]
The Rift Valley lakes are a series of lakes in the East African Rift valley that runs through eastern Africa from Ethiopia in the north to Malawi in the south, and includes the African Great Lakes in the south. These include some of the world's oldest lakes, deepest lakes, largest lakes by area, and largest lakes by volume.
Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [2] The general distinction between pools/ponds and lakes is vague, but Brown [1] states that ponds and pools have their entire bottom surfaces exposed to light, while lakes do not. In addition, some ...
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]
Map of the Lake Baikal Rift Zone from the USGS factsheet. The Baikal Rift Zone is a series of continental rifts centered beneath Lake Baikal in southeastern Russia. Current strain in the rifts tends to be extending with some shear movement. A series of basins form along the zone for more than 2,000 kilometres (1,200 mi), creating a rift valley.
Tectonic lakes are lakes formed by the deformation and resulting lateral and vertical movements of the Earth's crust. These movements include faulting, tilting, folding, and warping. Some of the largest lakes on Earth are rift lakes occupying rift valleys, e.g. Central African Rift lakes and Lake Baikal.
The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva.Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae).
