The physical Geography in Africa! By Aadhyah, Atharv, Hossam and Tarun. Climate in Africa • Africa's climate is dominated by desert conditions along vast stretches of its northern and southern fringes. The central portion of the continent is wetter, with tropical rainforests, grasslands, and semi-arid climates.Sub-Saharan Africa has four climate zones: desert,semiarid or Sahel, savanna (grasslands), and tropicalforests.Precipitation intensity is always high, and it is a hot Continent. Warm and hot climates prevail all over Africa,but mostly the northern part is marked by aridity and high temperatures. Only the northernmost and the southernmost fringes of the continent have a Mediterranean climate. • BY ATHARV Water in Africa • There are seven major African Great Lakes: Lake Albert, Lake Edward, Lake Kivu, Lake Malawi, Lake Tanganyika, Lake Turkana, and Lake Victoria. Lake Victoria, the largest lake in Africa, is the southern source of the Nile River, the longest river in the world. • BY AADHYAH Relief in Africa • A plateau covers the largest part of the country (South Africa) dominating the topography; it is separated from surrounding areas of generally lower elevation by the Great Escarpment. The plateau consists almost entirely of very old rock of the Karoo System, which formed from the Late Carboniferous Epoch (about 32o to 300 million years ago) to the Late Triassic Epoch (about 23o to 200 million years ago). The plateau, generally highest in the east, drops from elevations of more than 8,000 feet (2,40o metres) in the basaltic Lesotho region to about 2,000 feet (600 metres) in the sandy Kalahari in the west. The central part of the plateau comprises the Highveld, which reaches between 4,00o and 6,000 feet (1,200 and 1,800 metres) in elevation. South of the Orange River lies the Great Karoo region. • BY TARUN Vegetation in Africa • General form of vegetation: forest, woodland, scrub, grassland, desert. • Mangrove forests are the most common vegetation. Mangroves have exposed root systems. This allows the trees to absorb oxygen directly from the air, as well as from the nutrient-poor soil. Most of Africas native rain forest has been destroyed by development, agriculture, and forestry. • BY HOSSAM
