The Great Rift Valley begins in the country of Lebanon in Western Asia, specifically in the Beqaa Valley. This region is known for its geological significance as the starting point of the Great Rift Valley which stretches through Africa. The rift system in Lebanon marks the initial stages of the formation of the valley, characterized by tectonic plate movement and the gradual separation of the African and Arabian plates.
The Great Rift Valley then extends southward through countries in East Africa such as Ethiopia, Kenya, Tanzania, and Mozambique, showcasing diverse landscapes, lakes, and geological formations along its path. The valley's formation has played a crucial role in shaping the topography and ecosystems of the regions it traverses, making it a significant area for geological and biological studies.
