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 ...
The background map and the locator map are raster images embedded into the SVG file. The term Great Rift Valley is most often used to refer to the valley of the East African Rift , the divergent plate boundary which extends from the Afar Triple Junction southward through eastern Africa , and is in the process of splitting the African Plate into ...

In classical antiquity, Africa (also Libya) was assumed to cover the quarter of the globe south of the Mediterranean, an arrangement that was adhered to in medieval T and O maps . The only part of Africa well known in antiquity was the coast ...
In the Eulerian specification of a field, the field is represented as a function of position x and time t. For example, the flow velocity is represented by a function. On the other hand, in the Lagrangian specification, individual fluid parcels are followed through time. The fluid parcels are labelled by some (time-independent) vector field x0.
In paleoanthropology, the recent African origin of modern humans or the " Out of Africa " theory ( OOA) [ a] is the most widely accepted [ 1][ 2][ 3] model of the geographic origin and early migration of anatomically modern humans ( Homo sapiens ). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then ...
