GEOLOGY

Detailed explanation-1: -Many rift valleys are part of “triple junctions, ” a type of divergent boundary where three tectonic plates meet at about 120° angles. Two arms of the triple junction can split to form an entire ocean. The third, “failed rift” or aulacogen, may become a rift valley.

Detailed explanation-2: -The term Great Rift Valley is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward through eastern Africa, and is in the process of splitting the African Plate into two new and separate plates.

Detailed explanation-3: -Great Rift Valley (The Best Example of a Divergent Boundary) The Great Rift Valley is a geographical feature running north to south for around 6, 400 kilometres from northern Syria to central Mozambique in East Africa.

Detailed explanation-4: -Geologists know that the Rift Valley was formed by violent subterranean forces that tore apart the earth’s crust. These forces caused huge chunks of the crust to sink between parallel fault lines and force up molten rock in volcanic eruptions.

Detailed explanation-5: -Ocean Rift Valley Examples Separation of the Eurasian and North American plates, and the African and South American Plates, helped to create the Mid-Atlantic Ridge. This Mid-Ocean Ridge is formed by the process of seafloor spreading.
