   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.

   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 ...

   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.

   Oct 25, 2024 · glacial trough. A relatively straight, steep-sided, U-shaped valley that results from glacial erosion. Its cross profile approximates to a parabola, while its long profile is often irregular, with rock bars (riegel) and over-deepened rock basins being typical features.

   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

   What is a trough in geology?

   • 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.

   What does trough mean?

   • 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 ‘equatorial trough’, where trade winds meet, is synonymous with the ‘intertropical convergence zone’.) See also long wave. 2 The lowest point of a fold surface.

   What does a trough look like?

   • Troughs are marked with a black dashed line, and ridges with a white zig-zag line. However, this flow is unstable, allowing small disturbances (e.g., flow over mountain ranges) to grow into large north-south meanders (Fig. 11.49b) of the jet stream. These meanders are called Rossby waves or planetary waves. Typical wavelengths are 3 - 4 Mm.

   What is trough cross-bedding?

   • Trough cross-bedding in the Waddens Cove Formation (Pennsylvanian), Sydney Basin, Nova Scotia. 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.

   How many waves are in a trough?

   • Typical wavelengths are 3 - 4 Mm. Given the circumference of a parallel at those latitudes, one typically finds 3 to 13 waves around the globe, with a normal zonal wavenumber of 7 to 8 waves. The equatorward region of any meander is called a trough (pronounced like “troff”) and is associated with low pressure or low geopotential height.
