WebRift valleys are formed due to tectonic plate movement in the earth’s crust. Due to constant collision and moving away of the plates deep cracks (faults) may form. The land area between two cracks may be forced down exposing steep slopes. The folds which result when two continental plates strike against each other also give rise to valleys. WebThe rift system consists of three microplates, the Victoria Microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria Microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS.
