Rift valleys are also known to occur on other terrestrial planets and natural satellites. The 4,000 km long Valles Marineris on Mars is believed by planetary geologists to be a large rift system. [ 7 ] [ 8 ] Some features of Venus, most notably, the 4,000 km Devana Chasma [ 9 ] and a part of the western Eistla, and possibly also Alta and Bell ...
Map of the Great Rift Valley. The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6,000 or 7,000 kilometres (4,300 mi) in total length, the definition varying between sources, that runs from the southern Turkish Hatay Province in Asia, through the Red Sea, to Mozambique in Southeast Africa.
Lake Magadi is the most southern rift valley lake in Kenya, although the northern end of Lake Natron in Tanzania reaches into Kenya. The Elgeyo escarpment forms part of the western wall. The Kerio Valley lies between the Tugen Hills and the Elgeyo escarpment at an elevation of 1,000 metres (3,300 ft) There are large deposits of Fluorite in the ...
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.
(The ridge also has a secondary rift valley running its length.) The width is an average taken along the spreading ridges (Georgia–Senegal, Brazil – Bight of Benin, etc.). The greatest depth is the Romanche Trench. (The Puerto Rico Trench is not part of the rift system.) Great Rift Valley: 6,000 km (3,700 mi) 220 km (140 mi) 2 km (1 mi)
This was changed by the formation of the Great Rift Valley. A rift is a weak place in Earth's crust due to the separation of two tectonic plates, often accompanied by a graben, or trough, in which lake water can collect. This rift began when East Africa, impelled by currents in the mantle, began separating from the rest of Africa, moving to the ...
You often find geological features like rift valleys, volcanos and geysers in areas where plates are pulling apart. And you find mountains where they are coming together, like the Himalayas, which ...
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. [1] It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor.
