What type of sediment dominates the seafloor adjacent to continents?

Terrigenous sediment, which consists of material eroded from the continents such as sand, silt, and clay, dominates the seafloor adjacent to continents. This sediment is transported to the ocean by rivers, wind, and glaciers, and accumulates near the continental margins. It is one of the most common types of sediment found in the world's oceans.
