Trough (geology)

Short description: Linear structural depression that extends laterally over a distance

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.

Examples of oceanic troughs

Benue Trough
Cayman Trough^[1]
Hesperides Trough
Kings Trough
Mariana Trough
Nankai Trough
Northumberland Trough
Okinawa Trough in the East China Sea
Rockall Trough and others along the rift of the mid-oceanic ridge
Salton Trough
South Shetland Trough
Suakin Trough^[2] in the Red Sea
Timor Trough^[3]
