उत्तर
The Great Rift Valley is a long narrow valley formed as a result of vertical cracks that developed because of movements within the earth. It extends for a total distance of 5,000 km from Lake Malawi to the Red Sea and the Gulf of Aqaba to the Dead Sea in Jordan. Many freshwater lakes, such as Malawi, Tanganyika, and Turkana are found here.
