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.
May 28, 2023 · The equatorward region of any meander is called a trough (pronounced like “troff”) and is associated with low pressure or low geopotential height. The poleward portion of a meander is called a ridge, and has high pressure or height.
May 10, 2024 · Troughs form when the jet stream dips southward into a bowl-like shape, and are associated with colder air, low pressure aloft, and a less stable atmosphere. This tends to result in cooler and more unsettled weather conditions.

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
Trough –rille–pit systems occur scattered in the northern Gordii region (Fig. 4.11A), parallel to the Olympica 1–3 channels on both sides, and on the banks of central Olympica Fossa.
