The Amazon River deposits the greatest amount of sediments in the ocean. This is due to its large drainage basin, high sediment load, and fast-flowing currents. The Amazon carries approximately 20% of the world's freshwater discharge into the ocean, resulting in significant sediment deposition along its delta and coastal areas.

Neritic sediments are found in shallow water close to the coast, while pelagic sediments are found in deep open ocean areas. Neritic sediments tend to be coarser and more influenced by terrestrial input, while pelagic sediments are finer and accumulate slowly over time.
The oldest sediments recovered by deep-ocean drilling are around 180 million years old. These sediments are typically found in the Pacific Ocean and provide valuable information about Earth's history and past environmental conditions.
Ocean sediments are deposits of materials(organic or in-organic) at the substractum of the ocean.
terrigenous or continental sediments
The thickest deposits of terrigenous sediments typically form in continental margins, particularly in river deltas and along coastal areas where rivers discharge sediments into the ocean. These sediments accumulate in basins and can be further thickened by processes like tectonic activity and sediment compaction. Additionally, areas with strong currents or sediment transport mechanisms, such as submarine canyons, can also contribute to significant terrigenous sediment deposits.

The sediments found on the ridge of the ocean floor are primarily known as "pillow lavas" and "basaltic sediments." These sediments are formed from volcanic activity, where magma erupts and cools rapidly upon contact with seawater, creating pillow-shaped formations. Additionally, hydrothermal vent deposits and other sediment types, such as biogenic and pelagic sediments, can also be present in these regions.
Hydrogenous sediments form when minerals precipitate directly from seawater as a result of chemical reactions or biological processes. For example, manganese nodules and phosphorite deposits are examples of hydrogenous sediments that form in this way in the deep sea. These sediments accumulate slowly over time on the ocean floor.
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.

These are sediment particles, such as sand, silt, and clay, that settle down due to gravity. Over time, these sediments accumulate to form layers called sedimentary deposits.
The amount of seafloor sediments can vary widely depending on location. Generally, it ranges from a few centimeters to several kilometers thick. Factors such as proximity to land, ocean currents, and sediment sources influence the accumulation of sediments on the seafloor.
Example: The Wind Stops Blowing Or A River Enters A Quiet Lake Or The Ocean. In Each Case The Particles Being Carried Will Settle out, Forming Layers Of Sediment.
