What is the largest rift valley in the world?
The largest and deepest rift valley yet discovered is not on Earth—it’s on Mars. Valles Marineris was formed millions of years ago, when the rocky Martian lithosphere was still rifting and shifting. Valles Marineris reaches depths of up to 7 kilometers (4 miles) and spans about 4,000 kilometers (2,500 miles) long.

Why is the Great Rift Valley famous?
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 ...

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 does rainfall impact Africa?
Increases in temperature and changes in rainfall patterns also significantly affect population health across Africa. Warmer temperatures and higher rainfall increase habitat suitability for biting insects and the transmission of vector-borne diseases such as dengue fever, malaria and yellow fever.
Is the Great Rift Valley a grassland?

Why is the Great Rift Valley such an important geographical feature of East Africa?
The Great Rift Valley provides evidence of a split in the African Plate, dividing it into two smaller tectonic plates : the Somalian Plate and the Nubian Plate. The Great Rift Valley in East Africa is divided into the Western Rift and the Eastern Rift.
