Origin
terrigeneous, biogeneous, and hydrogeneous
The three types of ocean floor sediments are terrigenous (derived from land sources), biogenous (derived from biological organisms), and hydrogenous (derived from chemical processes in seawater).
The soil found in ocean biomes is primarily composed of sediments, which include particles such as sand, silt, and clay. These sediments accumulate on the ocean floor over time and can vary in composition depending on factors like currents, wave action, and proximity to land. The biota that inhabit these ocean sediments play crucial roles in nutrient cycling and ecosystem functioning.
Ocean floor sediments primarily consist of three types: terrigenous, biogenous, and hydrogenous sediments. Terrigenous sediments originate from land, including clays and silts brought by rivers and wind. Biogenous sediments are formed from the remains of marine organisms, such as foraminifera and diatoms, while hydrogenous sediments precipitate directly from seawater, including minerals like manganese nodules. Additionally, cosmogenous sediments, derived from extraterrestrial sources like meteorites, are also present but in smaller amounts.
Ocean sediments are deposits of materials(organic or in-organic) at the substractum of the ocean.
There are two types of deep ocean sediments, abyssal clay and biogenous oozes. Abyssal clays are fine-grained sediment, while biogenous ooze is composed of the hard parts of microscopic organisms.

Sediments build up in the Abyssal plain.
The sediments are called silt or alluvium. The land formed from these sedimants where the river meets the ocean is a delta.
The further from the delta, the finer the sediments deposited.
