“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. The three plates are separating at different speeds.
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.
What is happening to 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.
What is happening at the Rift Valley?
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.
What is the cause of the rift valleys in 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. … South of the Red Sea Rift lies the massive, complex East African Rift.
What countries does the Great Rift Valley extend through?
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.
|Name of basin||Total area of basin||Area in the country|
|Southern lakes:||178 800|
Which is the longest rift valley in the world?
|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)|
Is Africa breaking apart?
It is an active continental rift that began millions of years ago, splitting at 7mm annually. The regular eruption of volcanoes along the rift and new insights into the break up of continents adds to the belief that the continent may be splitting to form a new ocean.
Is Africa continent breaking 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.
Is the Great Rift Valley getting bigger?
(Read more about the social rifts felt in this region.) A rift valley refers to a lowland region where tectonic plates rift, or move apart. … The rifts are growing larger as two tectonic plates, the Somali plate in the east and the Nubian plate in the west, move away from each other.
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.
How deep is the Great Rift Valley?
The Rift Valley varies mostly between 2000 and 3000 feet (600 to 900 meters) in depth, with a maximum of 8860 feet (2700 meters) at the Gikuyu and Mau escarpments.
How did the Great African Rift Valley form?
Africa’s Great Rift Valley is a 6,000-mile crack (fissure) in the earth’s crust, stretching from Lebanon to Mozambique. … Geologists know that the Rift Valley was formed by violent subterranean forces that tore apart the earth’s crust.
Why the Great Rift Valley in Africa is a good example of divergent convergence?
Great Rift Valley (The Best Example of a Divergent Boundary) … In a southwest direction, the fault continues as the Great Rift Valley, which split the older Ethiopian highlands into two halves. In eastern Africa, the valley divides into the Eastern Rift and the Western Rift.
Why Rift Valley has steep sides?
c) Rift valleys have steep sides because they are formed when the earth crust is divided, they are not like those valley which are formed by soil erosion.
What is the African Rift Zone?
A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6–7 mm (0.24–0.28 in) per year.
