Great Rift Valley

The Great Rift Valley (GRV) is a series of contiguous geographic depressions, approximately 6,500 kilometres (4,000 mi) in total length, which, in its original definition, runs from "the plains of northern Syria" in the north, through the Red Sea, to Mozambique in the south. The term remains in use in the fields of geography, zoology, ecology, paleontology and other disciplines, but it is now rarely used in geology where the term "Afro-Arabian Rift System" is preferred, which describes the series of geological structures that have given rise to the geographical feature. Great Rift Valley is also often used to refer to valleys, such as the Kenyan Rift Valley, within the East African Rift system.
