The modern, arid Sahara. The Sahara was not a desert during the African humid period. Instead, most of northern Africa was covered by grass, trees, and lakes. The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today.
The Ironstone Plateau takes its name from the hard red lateritic soil called ironstone that covers almost the entire area. These soils are often thin and may be unsuitable for agriculture, except in the Green Belt in the extreme southwest of Western Equatoria and in a region around the Acholi Mountains in the Torit County of Eastern Equatoria.

Topography of Africa. There are many plateaus in Africa. The high southern and eastern plateaus, rarely falling below 600 m (2,000 ft), have a mean elevation of about 1,000 m (3,300 ft). The South African plateau, as far as about 12° S, is bounded east, west and south by bands of high ground which fall steeply to the coasts. On this account ...
This is a stylized illustration of the Southern African Great Escarpment, based particularly on its appearance in the Great Karoo, where thick erosion resistant dolerite sills (represented by the thick black lines in the diagram) generally form the upper, sharp edge of the escarpment; in other parts of the escarpment hard erosion-resistant geological layers similarly form the upper, abrupt ...
A dambo is a class of complex shallow wetlands in central, southern and eastern Africa, particularly in Zambia, Malawi and Zimbabwe.They are generally found in higher rainfall flat plateau areas and have river-like branching forms which in themselves are not very large but combined add up to a large area.
African cycle: The break-up of Gondwana was accompanied by an eastward tilting of western South Africa and Namibia during the Late Cretaceous. [8] The ensuring erosion cycle that begun with the Mesozoic rifting and uplift of Gondwana ended in the Miocene , albeit judging from offshore sediments erosion was minimal already in the Oligocene ...
In May, Kenya hosted an Africa-wide soil health summit to discuss declining production, climate change and other issues that have increased food security concerns. Agriculture is a key part of the ...
The part of the plateau that lies in Nigeria is more popularly known as Gotel Mountains. The Adamawa Plateau is the source of many waterways, including the Benue River. The average elevation is about 3,300 feet (1,000 meters), [2] but elevations can reach as high as 8,700 feet (2,700 meters). [1] It is important for its deposits of bauxite. [1]
