çöküntü koyağı

Turkish - English

Definition of çöküntü koyağı in Turkish English dictionary

(Jeoloji) rift valley

A graben structure between two tectonic plates which are opening relative to each other

A mid-oceanic ridge system with central valleys

A deep fracture or break, about 25-50 km (15-30 miles) wide, in the earth's crust, creating an elongated valley bounded by two or more faults. a valley with very steep sides, formed by the cracking and moving of the Earth's surface. Elongated trough formed by the subsidence of a segment of the Earth's crust between dip-slip, or normal, faults. Rift valleys are usually narrow and long and have a relatively flat floor. The sides drop away steeply in steps and terraces. Rift valleys are found on the continents and along the crests of oceanic ridges. They occur where two plates that make up the Earth's surface are separating (see plate tectonics). Submarine rift valleys are usually centres of seafloor spreading, where magma wells up from the mantle. The most extensive continental rift valleys are those of the East African Rift System; other notable examples include Russia's Baikal Rift Valley and Germany's Rhine Rift Valley

a huge, trough-shaped valley created by faulting

a valley with steep sides; formed by a rift in the earth's crust

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 valley that has developed along a tectonic rift

a fault trough formed through tension The Alpine Valley is the premier example

valley formed by sinking of land between two faults

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 formed by a fault or crack in the earth's surface, generally of tensional origin
