Quizplus · Accepted Answer

Terrigenous sediments refer to those that originate from land sources such as weathering and erosion of rocks, volcanic activity, and atmospheric deposition. They are transported by rivers, wind, and glaciers to the ocean, making up a significant portion of marine sediments. Pelagic sediments, on the other hand, come from the oceanic realm, including the shells of marine organisms, volcanic ash, and chemical precipitates. Neritic sediments are those found in shallow, nearshore areas. Sediments suspended in the water column are known as suspended sediments and do not make up a significant percentage of marine sediments. Sediments produced by active seamounts can be considered terrigenous or pelagic depending on their source.
