What is happening to the Great Rift African valley?
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.
Is the Great Rift valley still growing?
A crack that opened up in Kenya’s Rift Valley, damaging a section of the Narok-Nairobi highway, is still growing… Why does rifting happen? When the lithosphere is subject to a horizontal extensional force it will stretch, becoming thinner. Eventually, it will rupture, leading to the formation of a rift valley.
How deep is the Rift Valley in Africa?
In addition, over the past 25 million years, layers of soft sediment have accumulated on the lakebed. The actual floor of the rift valley is more than 5 kilometers (3 miles) deep. Lake Baikal also has the largest volume of liquid freshwater in the world—a staggering 23,615 cubic kilometers (5,700 cubic miles).
How does the Rift Valley look like?
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. 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.
What animals live in the Great Rift valley?
The Great Rift Valley’s inhabitants include lions, leopards, elephants, rhinos, buffaloes, cheetahs, giraffes, antelopes, zebras and primates.

Why are areas in the rift valley Hot?
Like many underwater rift valleys, the East Pacific Rise is dotted with hydrothermal vents. Geologic activity beneath the underwater rift valley creates these vents, which spew super-heated water and vent fluids into the ocean.
How are rift valleys made?
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.
Do people live 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.
How deep is the Great Rift valley?
between 2000 and 3000 feet
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.
