How does sediment transport differ between continental shelves and deep ocean basins?

Sediment transport on continental shelves is characterized by higher rates compared to deep ocean basins due to several factors. Continental shelves, being relatively shallow and often influenced by wave action, currents, and river runoff, experience significant sediment deposition and movement. The dynamic environment promotes the transport of sediments across these areas.

In contrast, deep ocean basins, which are much deeper and more stable, see sedimentation processes that are generally slower. While there is sediment present in deep ocean basins, the transport mechanisms are less vigorous due to the lack of significant currents and the distance from land sources of sediment, leading to a slower accumulation of sediments over time. The sediment in these basins usually comes from finer particles that have settled from the water column or have been transported over long distances, resulting in lower transport rates relative to continental shelves.

The key to understanding this difference lies in the physical characteristics and environmental conditions of each region, where continental shelves facilitate more active sediment movement and accumulation due to shallower depths and energy from waves and currents.
