The Great Rift Valley ( Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 7,000 kilometres (4,300 mi) in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa. [ 1] While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of ...
A rift valley near Quilotoa, Ecuador. A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion.
The Western Rift Valley includes the Albertine Rift, and farther south, the valley of Lake Malawi. The rift also continues offshore from the coast of Mozambique along the Kerimba and Lacerda grabens , which are joined by the Davie Ridge, a 2,200 km-long (1,400 mi) relic fracture zone that cuts across the West Somali basin, straddling the ...
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania . It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika . The geographical term includes the valley and the surrounding mountains.
The Southern Rift Valley lakes are like the Western Rift Valley lakes in that, with one exception, they are freshwater lakes. Lake Rukwa (about 5,670 square kilometres (2,190 sq mi) but quite variable) in Tanzania is the alkaline exception, lying south-east of Tanganyika, and has no outlet.
Great Rift Valley, Ethiopia. The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a "Great Rift Valley" that ran from Mozambique to Syria .
The Western Rift Valley lakes are freshwater and home to an extraordinary number of endemic species. More than 1,500 cichlid fish species live in the lakes, [7] as well as other fish families. The lakes are also important habitats for a number of amphibian species. Nile crocodiles are numerous. Mammals include elephants, gorillas and hippopotamus.
Gregory Rift in East Africa. The Gregory Rift ( Ufa la Gregori, in Swahili) is the eastern branch of the East African Rift fracture system. The rift is being caused by the separation of the Somali plate from the Nubian plate, driven by a thermal plume. Although the term is sometimes used in the narrow sense of the Kenyan Rift, the larger ...
