Your question: Where is East African Rift Zone?

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 is the East African Rift Zone?

The East African Rift (EAR) or East African Rift System (EARS) 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.

Where is the Rift Valley located in Africa?

The Rift Valley, located in Eastern Africa, covers just over 2% of the continent and spreads over seven countries (Map 5 and Table 29). min. max. The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

What is the African Rift Zone?

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.

What causes the East African Rift Zone?

The East African Rift is one of the great tectonic features of Africa, caused by fracturing of the Earth’s crust. The Somalian plate—which is moving away in the other direction—lies to the other side and includes the Horn of Africa. …

What is the East African Rift is an example of?

The East African Rift Valley is an example of a divergent boundary in an area of continental crust. It is one the geologic wonders of the world, a place where the earth’s tectonic forces are presently trying to create new plates by splitting apart old ones.

Where is Africa splitting apart?

Scientists say a new ocean will form in Africa as the continent continues to split into two. The East African Rift system made up the western and eastern continental rifts, and stretches from the Afar region of Ethiopia down to Mozambique.

Which country belong to Rift Valley of Africa?

The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

Which is the largest valley in Africa?

The Great Rift Valley is a series of contiguous geographic trenches, approximately 7,000 kilometres (4,300 mi) in total length, that runs from the Beqaa Valley in Lebanon which is in Asia to Mozambique in Southeast Africa.

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.

How old is the African Rift Valley?

The rift has been forming for some 30 million years (as Africa and the Arabian Peninsula separated) and has been accompanied by extensive volcanism along parts of its length, producing such massifs as Kilimanjaro and Mount Kenya.

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. … Two arms of the triple junction can split to form an entire ocean.

How is 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 of the rift passes through Ethiopia and Kenya, and the western branch forms a giant arc from Uganda to Malawi.

What will happen to the East African Rift in the future?

If these motions continue, plate models (mentioned below) suggest that Africa would rotate clockwise and eventually crash into Europe in 50 Ma in the future. The rift is growing at a rate of one inch per year through the upwelling of magma underneath the continental crust (see Fig. 3).

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.
