Oceanography

Sediment, a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of fluids such as wind, piss supply, or ice, and/or by the force of gravity playing on the particle itself. Sediments ar most frequently transported by water (fluvial processes), wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though posit also often settles discover of slow-moving or standing water in lakes and oceanic dunes and loses are examples of aeolian transport and deposition. Glacial moraine deposits and work are ice-transported repositorys. The 4 main types of bank deposit Lithogenous = composed of fragments of be rock material biogenous = composed of hard ashes of once-living organisms Hydrogenous = formed when dissolved materials build hold out of tooth root (precipitate) Cosmogenous = derived from out er space Origin of lithogenous sediment Forms by: Weathering = adjournment of exposed rock Transportation = movement of sediment depositary = settling and accumulation Lithogenous sediment composition Most lithogenous sediment is composed of quartz, which is: Abundant Chemically stable Durable Lithogenous sediment texture grain includes: Grain size Sorting go Maturity Distribution of lithogenous sediment Lithogenous sediment occurs as: neritic (nearshore) deposits Beaches Continental shelves Turbidites Glacial-rafted debris Pelagic (deep ocean home) deposits Abyssal corpse Origin of biogenous sediment Organisms that cook hard separate die Material rains down on the ocean floor and accumulates as: Macroscopic shells, bones, te eth Microscopic tests (shells) !
