  2. Rift valley - Wikipedia

    en.wikipedia.org/wiki/Rift_valley

    The most extensive rift valley is located along the crest of the mid-ocean ridge system and is the result of sea floor spreading.Examples of this type of rift include the Mid-Atlantic Ridge and the East Pacific Rise.

    (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)

  4. Great Rift Valley - Wikipedia

    en.wikipedia.org/wiki/Great_Rift_Valley

    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.

  5. Rift Valley lakes - Wikipedia

    en.wikipedia.org/wiki/Rift_Valley_lakes

    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.

  6. Great Rift Valley, Ethiopia - Wikipedia

    en.wikipedia.org/wiki/Great_Rift_Valley,_Ethiopia

    The Ethiopian Rift Valley lakes occupy the floor of the rift valley between the two highlands. Most of the Ethiopian Rift Valley lakes do not have an outlet, and most are alkaline. Although the Ethiopian Rift Valley Lakes are of great importance to Ethiopia's economy, as well as being essential to the survival of the local people, there were no ...

  7. Mid-Atlantic Ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-Atlantic_Ridge

    The Mid-Atlantic Ridge includes a deep rift valley that runs along the axis of the ridge for nearly its entire length. This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates.

  8. East African Rift - Wikipedia

    en.wikipedia.org/wiki/East_African_Rift

    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.

  9. Divergent boundary - Wikipedia

    en.wikipedia.org/wiki/Divergent_boundary

    Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley. Divergent boundaries can create massive fault zones in the oceanic ridge system.
