Linear structural depression that extends laterally over a distance
For troughs created by glaciation, see Glacial trough.
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/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
- 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 in the Red Sea
- Timor Trough
