Sep 29, 2024 · 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.
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.

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. Category: Landforms.

Biogeography refers to the distribution of various species and ecosystems geographically and throughout geological time and space. Biogeography is often studied in the context of ecological and historical factors which have shaped the geographical distribution of organisms over time. Specifically, species vary geographically based on latitude, habi...
There are three main fields of biogeography: 1) historical, 2) ecological, and 3) conservation biogeography. Each addresses the distribution of species from a different perspective. Historical biogeography primarily involves animal distributions from an evolutionary perspective. Studies of historical biogeography involve the investigation of phylog...
Biogeography provides evidence of evolution through the comparison of similar species with minor differences that originated due to adaptations to their respective environments. Over time, the Earth’s continents have separated, drifted apart, and collided, resulting in the creation of novel climates and habitats. As species adapted to these conditi...

Feb 23, 2024 · Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. This field of study helps us understand how organisms and biological communities vary along geographic gradients such as latitude, elevation, isolation, and habitat area.
