Quick Answer: Where is the East 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.

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.

How was the East African Rift Valley formed?

The East African Rift Valley, as the region is known, formed where the Somalian and Nubian plates are pulling away from the Arabian Plate. … The eastern branch formed around 25 to 30 million years ago, whereas the western branch formed only 10 to 15 million years ago — or at least that’s what scientists thought.

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 boundary is the Great Rift Valley in Africa?

Today, the term 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 across eastern Africa, and is in the process of splitting the African Plate into two new separate plates.

Which is the longest rift valley of the world?

List

World Rift/Valley Length

Canadian Arctic Rift System 4,800 km (3,000 mi)
West Antarctic Rift System
Midcontinent Rift System 2,000 km (1,200 mi)

Is Africa splitting apart?

Scientists say a new ocean is being born. New satellite measurements are offering valuable tools to study the tectonic rift in one of the most geologically unique spots on the planet.

How is Rift Valley formed?

A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading. … Tectonic plates are huge, rocky slabs of Earth’s lithosphere—its crust and upper mantle.

How long is the East 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.

What type of fault is the East African Rift Valley?

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate.

How many volcanoes are in the East African Rift Valley?

More than 100 young volcanoes – that have had activity within about 10,000 years – dot the landscape of the East African Rift – an area that runs for more than 3000 kilometres from Djibouti and Eritrea, down through Ethiopia, Kenya, Uganda and Rwanda to the Democratic Republic of Congo and Tanzania.

What is the importance of Rift Valley?

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 …

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.

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.

How does the Great Rift Valley affect Africa?

This area is part of the Great Rift Valley, where Africa is slowly pushed and pulled apart by uprising material in earth’s mantle. Eventually, the rift will become deep enough to host a new ocean, separating Eastern Africa from the rest of the continent.
