Great Rift Valley (disambiguation)

Last updated

The Great Rift Valley is a series of connected geographic valleys from Lebanon to Mozambique.

Great Rift Valley continuous geographic trench

The Great Rift Valley is a series of contiguous geographic trenches, approximately 6,000 kilometres (3,700 mi) in total length, that runs from the Beqaa Valley in Lebanon in Asia to Mozambique in southeastern Africa. While the name continues in some usages, it is rarely used in geology nowadays as it is considered an imprecise merging of separate though related rift and fault systems.

Great Rift Valley may also refer to:

Great Rift Valley, Ethiopia

The Great Rift Valley of Ethiopia, 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.

Great Rift Valley, Kenya Part of an intra-continental ridge system that runs through Kenya

The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. It was formed on the "Kenyan Dome" a geographical upwelling created by the interactions of three major tectonics: the Arabian, Nubian, and Somalian plates. In the past, it was seen as part of a "Great Rift Valley" that ran from Madagascar to Syria. Most of the valley falls within the former Rift Valley Province.

African Great Lakes Series of lakes in the Rift Valley

The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. They include Lake Victoria, the third-largest fresh water lake in the world by area, Lake Tanganyika, the world's second-largest freshwater lake by volume and depth, and Lake Malawi, the world's eighth-largest fresh water lake by area. Collectively, they contain 31,000 km3 of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planet's unfrozen surface fresh water. The large rift lakes of Africa are the ancient home of great biodiversity, and 10% of the world's fish species live there.

Rift Valley lakes group of lakes in the East African Rift

The Rift Valley lakes are a series of lakes in the East African Rift valley that runs through eastern Africa from Ethiopia in the north to Malawi in the south, and includes the African Great Lakes in the south. These include some of the world's oldest lakes, deepest lakes, largest lakes by area, and largest lakes by volume. Many are freshwater ecoregions of great biodiversity, while others are alkaline "soda lakes" supporting highly specialised organisms.

East African Rift An active continental rift zone in East Africa

The East African Rift (EAR) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. In the past it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor.

Afar Triangle A geological depression caused by the Afar Triple Junction

The Afar Triangle is a geological depression caused by the Afar Triple Junction, which is part of the Great Rift Valley in East Africa. The region has disclosed fossil specimens of the very earliest hominins, that is, the earliest of the human clade; and it is thought by some paleontologists to be the cradle of the evolution of humans, see Middle Awash, Hadar. The Depression overlaps the borders of Eritrea, Djibouti and the entire Afar Region of Ethiopia; and it contains the lowest point in Africa, Lake Asal, Djibouti, at 155 m below sea level.

The name Great Valley may refer to:

<i>Papilio echerioides</i> species of insect

Papilio echerioides, the white-banded swallowtail, is a butterfly of the family Papilionidae. It is found in Sub-Saharan Africa.

<i>Pseudacraea eurytus</i> species of insect

Pseudacraea eurytus, the false wanderer, is a butterfly of the family Nymphalidae. It is found in Africa.

<i>Papilio rex</i> species of insect

Papilio rex, the regal swallowtail or king papilio, is a butterfly of the family Papilionidae. It is found in Africa.

Gregory Rift

The Gregory Rift 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 definition of the Gregory Rift is the set of faults and grabens extending southward from the Gulf of Aden through Ethiopia and Kenya into Northern Tanzania, passing over the local uplifts of the Ethiopian and Kenyan domes. Ancient fossils of early hominins, the ancestors of humans, have been found in the southern part of the Gregory Rift.

Losiolo Escarpment mountain in Kenya

The Losiolo Escarpment is an escarpment on the east side of the Great Rift Valley, Kenya. Rising 2,000 metres (6,600 ft) above the Suguta Valley floor on the east side near Maralal, the escarpment provides one of the most dramatic views of the Kenyan rift valley. The escarpment, which is also known as 'World's End', is the longest vertical drop in the Rift Valley.

Turkana Basin

The greater Turkana Basin in East Africa determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia. The deepest point of the basin is the endorheic Lake Turkana, a brackish Soda lake with a very high ecological productivity in the Gregory Rift.
