A rift valley is created past the activeness of a geologic rift or fault. A fault is a cleft in the terrestrial surface in which the rock material on the upper side of the mistake airplane has been displaced downward relative to the stone below the fault. In simpler words, it forms where the earth's chaff, or outermost layer, is scattering or splitting autonomously. This kind of valley is frequently narrow, with steep sides and a flat flooring. Rift valleys are also chosen grabens, which means "ditch" in German.

A continental rift valley comprises of a blazon of tectonic valley and, differs from river and glacial valleys. River valleys are produced past erosional forces. The theory of plate tectonics states that they occur in divergence zones, belts where two of the various lithospheric plates that make up the Earth's surface are departing. A new body of water begins when hot drapery cloth begins to motion upward beneath a continent. Geoscientists are still non certain nigh why that happens. The lithosphere of the continent bulges upward and is stretched sideways. Eventually its breaks forth a long crack, called a rift. Magma rises upward to feed volcanoes in the rift. As the rift widens, the ocean invades the rift. A new ocean bowl has at present been formed, and it gets wider as time goes on.

Rift valleys are commonly narrow and long, some measuring hundreds of kilometers in length. Their floors are relatively apartment, attributable in big office to volcanic degradation and marine or lacustrine sedimentation. The sides of rift valleys driblet steeply away in the class of steps and terraces. At their margins, the walls of the valleys may rise hundreds of meters.The Great African Rift Valley, the Baikal Rift Zone and the Due west Antarctic Rift are the classic examples of rift valleys.
