1. A valley of regional extent formed by block faulting in which tensional stresses tend to pull the crust apart. Synonymous with graben. 2. The down-dropped block along divergent plate margins.
A long, narrow valley formed by land sinking between two parallel faults.
trench like valley with steep, parallel sides
a valley with steep sides; formed by a rift in the earth's crust
a down-dropped area bounded by faults and fractures that are created when the earth's crust is pulled apart
a zone of weakness and thinning in the earth's crust
A valley formed by a fault or crack in the earth's surface, generally of tensional origin
a steep sided valley formed by the uplift and subsequent subsidence of the earth's crust. In Africa the Great Rift Valley runs from the Red Sea to Mozambique.
valley formed by sinking of land between two faults. alinity: proportion or amount of salt in water.
A valley formed when the strip of land between two faults subsides.
The trough formed between two fault zones.
a huge, trough-shaped valley created by faulting
An elongated valley formed by the depression of a block of the planet's crust between two faults or groups of faults of approximately parallel strike.
A valley that has developed along a tectonic rift.
A rift valley in geology is a valley created by the formation of a rift. The Great Rift Valley, located in the Middle East and Africa, is the most famous of the world's rift valleys. Rift valleys are produced by tensional tectonic forces which occur at divergent plate boundaries.
