what divides africa in half
Tweet. One of the two most prominent divides in Africa is the Great Rift Valley, the geological scar that runs north and south along the eastern half of the continent and has been forming over eons as the African tectonic plate slowly splits into two.he other great divide does not have a name, is not visible on physical maps of the continent, and runs east and west. It is the blurry boundary along the Sudanian Savanna where largely Muslim North Africa meets the areas to the south inhabited mostly by Christians and adherents of native religions.
