How did the East African Rift Valley form?
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.
Is the East African Rift a divergent boundary?
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 caused the Great Rift Valley?
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.
Which is the largest rift valley in the world?
Valles Marineris
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 |
|---|---|---|
| Sudan | 16 441 | |
| Uganda | 4 514 | |
| Kenya | 102 452 | |
| Southern lakes: | 178 800 |
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.
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.
Which location is on a major rift valley?
The most well-known rift valley on Earth is probably the so-called “Great Rift Valley System” which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.
Is a rift valley convergent or divergent?
Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. Rift valleys are formed by divergent boundaries that involve continental plates.
Which lakes are part of the Great Rift Valley?
The lakes are; Lake Elementaita (6,300 ha), Lake Nakuru (18,800ha) and Lake Bogoria (10,700ha) all of which lie in basins on the floor of the Great Rift Valley which transects Kenya North-South. All the three lakes are shallow, alkaline and are hydro-geologically connected through sub surface seepage of water.

Can a river be man-made?
This is fascinating: Apparently geologists have spent decades assuming that the shapes of Mid-Atlantic-state rivers were natural — when they’re actually man-made. But it turns out that those ribbon-straight rivers were in fact affected by human development, as two scientists — Robert C. Walter and Dorothy J.
