In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors.
Sep 29, 2024 · Quick Reference. 1 An extension of low atmospheric pressure from the central regions of a low-pressure system into a zone where generally higher pressure prevails. The term ‘trough’ is also, and in accordance with this definition, applied to equatorward meanders of the flow of the upper westerly winds over middle latitudes. (The ...
In geology, a trough refers to a linear depression that extends in one direction over a distance. It is less steep than a trench. A trough can be a narrow basin or a geologic rift. There are various oceanic troughs, troughs found under oceans; examples include the rifts along the mid-ocean ridges

These are valleys formed by the glacial processes of weathering, erosion and transportation. They have steep sides and flat floors. Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance.
