Submarine Canyons
Erosional features on the continental shelf and slope that transport sediment and organic matter offshore, functioning as major conduits in coastal sediment systems.
Real World
The Monterey Canyon off California's coast extends 153 km offshore and reaches depths of 3,600 metres, regularly funnelling sand and organic debris from the coast into the deep ocean via turbidity currents.
Exam Focus
For 'assess' questions on sediment systems, explicitly state whether canyons act as sources, transfers, or sinks — examiners credit correct terminology.
