Oceanography

Sediment, a naturally occurring veridical that is broken stack by processes of weathering and erosion, and is subsequently transported by the execute of fluids such as wind, pissing supply, or ice, and/or by the force of gravity playacting on the particle itself. Sediments be most practically transported by water (fluvial processes), wind (Aeolian processes) and glaciers. brink sands and river channel deposits be 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 gutter are ice-transported sediments.

The 4 main(prenominal) types of sediment Lithogenous = composed of fragments of pre-existing contestation material biogenous = composed of fleshy remains of once-living organisms Hydrogenous = formed when change state materials build hold away of solution (precipitate) Cosmogenous = derived from outer space start of lithogenous sediment Forms by: Weathering = licentiousness of candid rock Transportation = movement of sediment attestation = settling and accumulation Lithogenous sediment composition near lithogenous sediment is composed of quartz, which is: Abundant chemically stable Durable Lithogenous sediment texture grain includes: ingrain size Sorting Rounding Maturity Distribution of lithogenous sediment Lithogenous sediment occurs as: Neritic (nearshore) deposits Beaches Continental shelves Turbidites Glacial-rafted debris pelagic (deep ocean traumatise) deposits Abyssal clay profligate of biogenous sediment Organisms that cook ponderous parts die Material rains down on the ocean floor and accumulates as: Macroscopic shells, bones, teeth microscopic tests (shells) If comprised of at...If you want to get a full essay, order it on our website: Orderessay
