What will happen if the East African rift continues?

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

However, researchers are uncertain about the future of the East African rift—whether the split will continue and an ocean will eventually be formed. At the rate at which the Afar rift is splitting, it will take tens of million years for an ocean to eventually be formed.

What will happen to the continent of Africa as the East African Rift continues to separate?

Over time, these rifting events will reshape the African continent. … “The Gulf of Aden and the Red Sea will flood in over the Afar region and into the East African Rift Valley and become a new ocean, and that part of East Africa will become its own separate small continent,” Macdonald said.

What will most probably happen to the East African rift over time?

Along the East African Rift Valley, African continent is splitting into two — the Somali plate and the Nubian plate. … Once the rift splits the continent, the ocean will flood the gap, creating a new continent in the Indian Ocean. In 10 million years, the Somali plate is expected to break off from the main African plate.

What will eventually happen if a rift valley continues to pull apart?

If these two rift zones continue they will break apart the crustal plates they are located on and will create new plates. Sea water will flood the rift valleys and they will eventually become seas like the Red Sea.

What will happen to Africa in the future?

Projections show that by 2050, Africa’s population will double. By 2100, one in three people on Earth will be African. This means that, by the end of the century, sub-Saharan Africa—which already has an extraordinarily young population—will be home to almost half of the young people in the world.

What are the future predictions of the Great rift Valley?

The new ocean created by this rift will be a continuation of the Red Sea; the divergent boundary between the African and Arabian plates. Within 10 Ma, the rift will be completely flooded by the encroaching sea and Somali will become an independent plate (Emerick and Duncan, 1982).

How does East African Rift relate to plate tectonics?

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. … The Nubian and Somalian plates are also separating from the Arabian plate in the north, thus creating a ‘Y’ shaped rifting system. These plates intersect in the Afar region of Ethiopia at what is known as a ‘triple junction’.

Is the earth cracking?

Long ago, Earth’s outer shell cracked into pieces, which we now call tectonic plates. … Approximately 4.5 billion years ago our home planet formed and, not too soon after — about 3.2 billion years ago — Earth’s shell cracked into these plates.

How was India separated from Africa?

However, the southern plate carrying India underwent a radical change: About 80 million years ago, a collision with Africa cut that plate down to 3,000 kilometers — right around the time India started to speed up. The team believes the diminished plate allowed more material to escape between the two plates.

What will happen to the East African rift in 5 million years?

“The Gulf of Aden and the Red Sea will flood in over the Afar region and into the East African Rift Valley and become a new ocean, and that part of East Africa will become its own separate small continent,” Macdonald said.

Is the Great Rift Valley still growing?

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.

Is the earth splitting apart?

The landmasses we see today have cruised around the globe, smashing together and splitting apart several times over the past 3 billion years. These cycles of amalgamation and dispersal have affected the Earth’s crust and underlying mantle, its atmosphere and climate, and the life it supports.

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 …

What could have caused the crack in the African rift Valley?

“Given the evidence available at present, the best and simplest explanation is that this crack was in fact formed by erosion of soil beneath the surface due to recent heavy rains in Kenya,” he wrote. Historically, such rifts are nothing new.

What forces result in the formation of rift valleys?

Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion. More generally the valley is likely to be filled with sedimentary deposits derived from the rift flanks and the surrounding areas.
