East African Rift System, also called Afro-Arabian Rift Valley, one of the most extensive rifts on Earth’s surface, extending from Jordan in southwestern Asia southward through eastern Africa to Mozambique. The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide.
What country is the Great Rift Valley in?
The Omo-Gibe basin, with rivers flowing into Lake Turkana (also called Lake Rudolph) is mainly located in Ethiopia and Kenya, with small parts in Sudan and Uganda.

Why Rift Valley is formation in East Africa?
Millions of years ago, the Arabian Peninsula was connected to Africa. Seafloor spreading caused the Arabian and African plates to rift apart. The Indian Ocean flooded the rift valley between the continents, creating the Red Sea. Today, Africa and Asia are connected by the triangle of the Sinai Peninsula.
What countries does the East African Rift Valley run through?
The EAR runs from the Afar Triple Junction in the Afar Triangle of Ethiopia through eastern Africa, terminating in Mozambique. The EAR transects through Ethiopia, Kenya, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi and Mozambique.
What is happening in the African Rift Valley?
Large crack in East African Rift is evidence of continent splitting in two. A large crack, stretching several kilometers, made a sudden appearance recently in south-western Kenya. The tear, which continues to grow, caused part of the Nairobi-Narok highway to collapse and was accompanied by seismic activity in the area.
Which is the longest rift valley of the world?
List
| World | Rift/Valley | Length |
|---|---|---|
| Earth | Great Rift Valley | 6,000 km (3,700 mi) |
| Canadian Arctic Rift System | 4,800 km (3,000 mi) | |
| West Antarctic Rift System | ||
| Midcontinent Rift System | 2,000 km (1,200 mi) |
Who lives in the Great Rift Valley?
An estimated 1,000 to 1,500 Hadza live in the central Great Rift Valley and the surrounding plains in north-central Tanzania, where they subsist almost entirely off the land: hunting animals, foraging for roots and fruit, gathering honey.
How long is the African Rift Valley?
East African Rift System, also called Afro-Arabian Rift Valley, one of the most extensive rifts on Earth’s surface, extending from Jordan in southwestern Asia southward through eastern Africa to Mozambique. The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide.
How is the African Rift Valley formed?
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.
How fast is Africa splitting apart?
The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year, according to Macdonald.
Why is the Rift Valley important to Africa?
The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is …
Why do rift valleys have volcanoes?
Rift volcanoes form when magma rises into the gap between diverging plates. They thus occur at or near actual plate boundaries. … Earthquake swarms and volcanic eruptions occur when the stretching exceeds the strength of the near-surface rocks, which then fracture along steeply dipping cracks parallel to the rift.
Where does Rift Valley start and end?
The Rift Valley starts all the way from Jordan, Middle-East, and runs through Ethiopia, Kenya, Tanzania, Congo, Malawi, and ends near the coastal town of Solada in Mozambique.
Is Africa breaking apart?
The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar — the long island just off the coast of Southeast Africa — that itself will also break apart into smaller islands.
Why is Africa called Africa?
In the early sixteenth century the famous medieval traveller and scholar Leo Africanus (al-Hasan ibn Muhammad al-Wazan), who had travelled across most of North Africa giving detailed accounts of all that he saw there, suggested that the name ‘Africa’ was derived from the Greek word ‘a-phrike’, meaning ‘without cold’, …
What if the African continent broke apart?
As the plates continue to pull away from each other, the rift valley will sink deeper and deeper, and water from the Red Sea will flood in to create a new ocean. Africa will become a lot smaller, as parts of southern Ethiopia and Somalia will drift off to form a new island.
