Which consequence results when longshore drift encounters a deepwater submarine canyon?

💡 Explanation

Sediment transported by longshore drift is funneled into canyons because gravity-driven turbidity currents form and increase off-shelf sediment transport; therefore, increased sediment plume turbidity occurs at the canyon’s mouth, rather than tombolo formation which require wave refraction on nearshore islands.
