In what setting does the thickest sediment accumulate in the oceans?

Question

Quizplus · Accepted Answer

Continental shelves and slopes along passive margins experience high rates of sediment accumulation due to the proximity of terrestrial sources of sediments and the relatively calm water conditions that allow sediments to settle and accumulate over time. Abyssal plain and mid-ocean ridges typically have lower sedimentation rates due to deeper water and more turbulent currents, while oceanic trenches may have variable sedimentation rates depending on local geologic and tectonic conditions.
