   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 is the difference between Ridge and trough?

   • A ridge is an elongated area of relatively high pressure that extends from the center of a high-pressure system. On the other hand, a trough is an elongated area of relatively low pressure that extends from the center of a low-pressure system. What Do Ridges and Troughs Indicate?

   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 are ridges and troughs on a weather map?

   • Ridges and troughs are key features of a weather map that can tell us a lot about the atmospheric pressure and weather conditions in a particular area. What are Ridges and Troughs? Ridges and troughs are areas of high and low pressure, respectively, that are represented on a weather map.

   How do Troughs form?

   • Troughs form when the jet stream dips southward, bringing colder air, low pressure, and less stability to the atmosphere. This often leads to cooler and more unsettled weather conditions. 2.

   Jun 22, 2024 · A trough is often associated with cloudy conditions, precipitation, and sometimes even a cold air mass. On the other hand, a ridge indicates relatively higher heights and is typically characterized by sinking air. This sinking air within a ridge tends to bring warmer and drier weather.

   Oceanic trough, an elongate depression in the seafloor that is characteristically shallower, shorter, narrower, and topographically gentler than oceanic trenches. Maximal depths of oceanic troughs range between 2,300 m (7,500 feet) in the Papuan Trough and 7,440 m in the Banda Trough.

   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
