In geology, a trough generally refers to a linear structural
Structural geology

Structural geology is the study of the three-dimensional distribution of Rock units with respect to their deformational histories. The primary goal of structural geology is to use measurements of present-day rock geometries to uncover information about the history of deformation in the rocks, and ultimately, to understand the stress field t...
 depression that extends laterally over a distance, while being less steep than a trench
Oceanic trench

The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor....
. A trough can be a narrow basin
Basin (geology)

A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat lying stratum. Structural basins are geological depressions, and are the inverse of dome s....

Rift

In geology, a rift is a place where the Earth's Crust and lithosphere are being pulled apart and is an example of extensional tectonics.Typical rift features are a central linear downdropped geologic fault segment, called a graben, with parallel normal faulting and rift-flank uplifts on either side forming a rift valley, where the rift r...

Ocean

An ocean is a major body of Seawater, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface is covered by ocean, a World Ocean that is customarily divided into several principal oceans and smaller seas....

Cayman Trough

The Cayman Trough, or Cayman Trench, also called Bartlett Deep, or Bartlett Trough, is a complex transform fault zone which contains a small Divergent boundary on the floor of the western Caribbean Sea between Jamaica and the Cayman Islands....
