Final answer:
The Great Rift Valley in East Africa extends from Mozambique in the south to the Red Sea region. It is comprised of the Western and Eastern Rifts and is associated with numerous deep water lakes and active volcanoes.
Step-by-step explanation:
The Great Rift Valley stretches between the cities of Mozambique in the south and continues all the way up to the Red Sea region. This geological feature provides evidence of the split in the African Plate, dividing it into the Somalian and Nubian Plates. It is made up of two primary sections; the Western Rift and the Eastern Rift. The Western Rift is accompanied by a series of deep water lakes like Lake Tanganyika and Lake Albert. On the eastern side of the Democratic Republic of the Congo, you find the Western Rift, which houses active volcanoes such as Mount Nyiragongo. The valley extends far north beyond Africa, reaching up to Lebanon in the Middle East, showcasing the extensive reach of this massive geographical structure.
