Submarine canyons are deep, steep-sided valleys that cut into the continental shelf and slope, typically formed by erosion from sediment-laden currents, underwater landslides, or turbidity currents. These geological features can extend for hundreds of kilometers and are often associated with river deltas or coastal sediment transport. Submarine canyons play a significant role in marine ecosystems, providing habitats for diverse marine life and influencing sediment distribution and ocean circulation.
What else can I help you with?
Which feature of the sea floor is cut by turbidity currents?
Submarine canyons are a common feature of the sea floor that can be cut by turbidity currents. These currents are fast-moving underwater sediment flows that can transport large amounts of sediment and carve deep channels into the ocean floor. With their high energy and ability to transport sediment, turbidity currents are capable of reshaping submarine canyons over time.
Explain how turbidity currents are related to submarine canyons?
Created by a series of complex processes, submarine canyons continue to be carved by sporadic turbidity currents waterfalls of sand, gravel, and muddy sediments.
What features of the seafloor are caused by turbidity currents?
Turbidity currents can create features such as submarine canyons, channel-levee systems, and turbidite deposits on the seafloor. These currents transport sediment downslope in the ocean, leading to the erosion and deposition of material that shapes the underwater landscape.
Submarine canyons are usually found in which region?
Submarine canyons are typically found on continental margins, where they cut through the continental slope and descend towards the abyssal plain. They are commonly associated with tectonically active regions or areas with high sediment input from rivers or glaciers.
Which feature is most likely to have been formed by flowing water?
Canyons are formed by flowing water.
Hudson and Monterey and Hatteras are examples of?
submarine canyons

What causes submarine canyons?
passive margins
Where do find submarine canyons?
Below the surface............
How is submarine canyons formed?
A submarine canyon refers to a steep-sided valley cut into the sea floor of the continental slope. It is formed through turbidity currents that carve out the submarine canyons in the continental shelf.
Deep valleys that run through a continental slope are called?
Submarine canyons. These are steep-sided valleys that cut into the continental slope and sometimes extend onto the continental shelf. Submarine canyons can be formed by various processes, including erosion from turbidity currents or underwater landslides.
How are turbidity current and submarine canyons related?
By mud slides
How are turbidity currents related to submarine canyons?
Created by a series of complex processes, submarine canyons continue to be carved by sporadic turbidity currents waterfalls of sand, gravel, and muddy sediments.
What are V shaped valleys in the continental shelf and continental slope are called?
V-shaped valleys in the continental shelf and slope are called submarine canyons. These are deep, steep-sided valleys that cut across the continental margin and are often formed by underwater processes such as turbidity currents or erosion by underwater currents. Submarine canyons can be comparable in scale to canyons found on land.
Explain how turbidity currents are related to submarine canyons?
Created by a series of complex processes, submarine canyons continue to be carved by sporadic turbidity currents waterfalls of sand, gravel, and muddy sediments.
How is a canyons formed?
A submarine canyon refers to a steep-sided valley cut into the sea floor of the continental slope. It is formed through turbidity currents that carve out the submarine canyons in the continental shelf.
It is thought that submarine canyons on the continental slope have been generated by?
turbidity currents
