The geology of Africa is varied and complex, and gives rise to the wide variety of landscapes found across the continent. The African continent rests over two main plates. The African Plate , accounting for the whole of north Africa, and the Somali Plate , which accounts for the eastern side of mid and southern Africa. [ 1 ]
The mountains are an exception to Africa's general landscape. Geographers came up with the idea of "high Africa" and "low Africa" to help distinguish the difference in Geography; "high Africa" extending from Ethiopia down south to South Africa and the Cape of Good Hope while "low Africa" representing the plains of the rest of the continent.

Features Africa , Atlantic Ocean , Mediterranean Sea , Red Sea The African plate , also known as the Nubian plate , is a major tectonic plate that includes much of the continent of Africa (except for its easternmost part ) and the adjacent oceanic crust to the west and south.

Spectacular hydrothermal features are a part of the Richat Structure. They include the extensive hydrothermal alteration of rhyolites and gabbros and a central megabreccia created by hydrothermal dissolution and collapse. The siliceous megabreccia is at least 40 metres (130 ft) thick in its center to only a few meters thick along its edges.
A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian plate and two parts of the African plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
Geological map of central Namibia Tectonic evolution of the Damara Belt Cross-section of the Damara Belt. Large areas of the Namibian geology exposed onshore are associated with the Late Proterozoic Pan-African orogenic cycle. [1]
During its wanderings, at different times covered by ice sheets, forests, marshes or arid desert, the surface of the West African Craton has been heavily eroded by ice, water and wind. In most places the original rocks are buried far below more recent volcanic and sedimentary deposits. The visible features are usually of comparatively recent ...
