Biogenous sediment (from bio, meaning life, and generare, meaning to produce)—also known as biogenic sediment—originates from the preserved hard remains of once-living organisms. Origin of Biogenous Sediment Biogenous sediment initially forms from the durable components (such as shells, bones, and teeth) of various living organisms, which range in size and complexity from microscopic algae and […]

Lithogenous sediment (from lithos meaning stone and generare meaning to produce) originates from pre-existing rock formations that are found on continental landmasses or islands. These sediments form through erosional processes, volcanic discharges, or atmospheric dust transport. It is important to note that lithogenous sediment is also known as terrigenous sediment (terra = land, generare =

The deep-ocean region extends beyond the continental margin province—which comprises the shelf, slope, and rise—and encompasses a diverse range of notable geological features. Abyssal Plains Stretching outward from the base of the continental rise into the expansive deep-ocean regions are extremely flat depositional surfaces characterized by inclinations of less than a degree. These regions, termed
