The predominant controls on the formation of the Lake Victoria Basin are tectonic uplift with associated rifting around the craton margins, and intersection among a series of NW-trending strike-slip faults which transect the craton.
Is Lake Victoria a tectonic?
Lake Victoria, formed as a result of tectonic uplift of the eastern and western rifts, is the largest freshwater lake in Africa and the second largest in the world in terms of surface area.
What type of lake is Victoria?
tropical lake
With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa’s largest lake by area, the world’s largest tropical lake, and the world’s second-largest fresh water lake by surface area after Lake Superior in North America.
How is Lake Victoria formed?
Lake Victoria is thought to have formed about 400,000 years ago by down-warping of land between the two arms of the Great Rift Valley. Westward-flowing rivers were dammed by an upthrown crustal block, reversing their flow into the down warped land.
Is Lake Victoria a Dimictic lake?
LNC is a large dimictic lake with a high altitude (4,731 m).
Which lake is tectonic lake?
Tectonic lakes including Lake Baikal, the Caspian Sea, and the Sea of Aral, are some of the examples of Tectonic lakes. Wular Lake is one of Asia’s largest freshwater lakes, having been produced by geological action.
What are tectonic lakes?
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.
Why can’t you swim in Lake Victoria?
The main worry about swimming in Lake Victoria is the risk of contracting bilharzia. There are also large populations of hippo and crocodiles in the lake.
Has Lake Victoria ever dried up?
“Historically, the level of Lake Victoria has dropped pretty drastically,” and past research has shown that the lake twice dried out completely, 15,000 and 17,000 years ago. The team’s research showed that the lake also dried out at least once more in the past 100,000 years.
Is Lake Victoria the biggest lake in the world?
Lake Victoria is the largest lake in Africa, the largest tropical lake in the world, the second largest freshwater lake in the world, and the third largest lake in the world.

What are 3 facts about Lake Victoria?
Many archipelagos are contained within the lake, as are numerous reefs, often just below the surface of the clear waters. Lake Victoria has more than 200 species of fish, of which the Tilapia is the most economically important. The lake’s basin area covers 92,240 square miles (238,900 square km).
What causes a Dimictic Lake?
thermal stratification
lakes occur, lakes exhibit a dimictic thermal pattern (two periods of mixing—in spring and autumn—per year) caused by seasonal differences in temperature and the mixing effects of wind (Figure 2).
Which lake has a tectonic origin?
The Wular lake is integral to the hydrological system of the Kashmir valley. India’s largest freshwater lake, the Wular lake was formed as a result of the tectonic activity and is fed by the Jhelum river.
Where are tectonic lakes located?
Rift Valleys
The most common type of lakes formed by tectonic movements are the ones located in the so-called “Rift Valleys”. These rifts are formed due to the divergent movement (or rift) of two plates. This forms a depression in between them.
How many types of tectonic lakes are there?
Lakes are classified depending on how they formed and on the quality of the water (freshwater or saltwater).
Which lake is the result of tectonic activity?
Wular Lake
Wular Lake (also spelt Wullar) is a large fresh water lake in Bandipore district in the Indian state of Jammu and Kashmir. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River.
What are the 3 tectonic environments?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform.
