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]
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
Proglacial lake – Lake formed by the action of ice; Pyramidal peak, also known as Glacial horn – Angular, sharply pointed mountainous peak; Outwash fan – Type of sediment deposition by a melting glacier; Outwash plain – Plain formed from glacier sediment transported by meltwater
[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 ...
At the base of the Crags, a lake forms temporarily each year. [7] Known as the Crags Lake [8] or the Chaos Crater, [9] it forms in a depression that acts as a basin to collect melted snow during the spring season. [8] The lake has cool temperatures near the shores, and grows colder near its center. It usually dries up by the end of August. [10]
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.
A volcanogenic lake is a lake formed as a result of volcanic activity. [1] They are generally a body of water inside an inactive volcanic crater ( crater lakes ) but can also be large volumes of molten lava within an active volcanic crater ( lava lakes ) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems.
