Africa is located in all four hemispheres: Eastern, Northern, Western, and Southern.
Africa’s absolute location affects its climate. The continent is in the tropical and sub-tropical zones.
East Africa is located at the boundary between tectonic plates. This affects the development of the East African topography

OTHER GEOGRAPHICAL FEATURES OF AFRICA
Great Rift Valley
• Great Rift Valley a geological fault system stretching about 6,400 km from the valley of the Jordan River in south western Asia to the Zambezi River in Mozambique. It is the longest fault system in the world.
• Elevations range from about 400 m below sea level in the Dead Sea to more than 1,800 m above sea level in southern Kenya.
• South of Ethiopia the Great Rift Valley divides into an eastern and a western branch. The eastern branch, which runs through Kenya and Tanzania, has many volcanoes and several shallow lakes.
• The western branch, which runs along the Democratic Republic of the Congo’s eastern frontier, is marked by a chain of large, deep lakes and has few volcanoes. The branches converge at Lake Nyasa, in southeastern Africa, and continue south as one system to central Mozambique.
• The deep rift valleys of the Eastern Highlands hold a great series of lakes. This equatorial lake system includes Lakes Turkana, Albert, Tanganyika, and Nyasa (Malawi).
• Lake Victoria, the largest lake in Africa and the third largest in the world, is, however, not part of this system.
The waterfall is in southern Africa on the Zambezi River, on the border of Zambia and Zimbabwe.
The fall is higher and wider than Niagara Falls measuring 1,600 m across and drop about 107 m in some parts.

• An arid coastal region in Namibia extending about 1,600 km from Angola in the north to South Africa in the south.
• It is 130 km wide and lies between a high inland plateau and the Atlantic Ocean.
• The weather is generally cool because of westerly winds moving inland from cold offshore water; morning fog is common.
• Annual rainfall is less than 1 inch (25 mm).
