In geology, a trough is a linear structural depression that extends laterally over a distance, while being less steep than a trench.
A trough can be a narrow basin or a geologic rift, often formed at the rim of a tectonic plate.
There are various oceanic troughs, troughs found under oceans; examples include
- the Cayman Trough[1]
- the Nankai Trough
- the Rockall Trough and others along the rift of the mid-oceanic ridge,
- the Timor Trough.[2]
