left by flooding from a breach in the London Avenue Canal . ]] Silt is produced by the mechanical Weathering of rock, as opposed to the chemical weathering that results in clays. This mechanical weathering can be due to grinding by Glacier s, Eolian Abrasion ( Sandblasting by the wind) as well as water Erosion of rocks on the Bed s of rivers and streams. Silt is sometimes known as 'rock flour' or 'stone dust', especially when produced by glacial action. Sedimentary Rock composed mainly of silt is known as Siltstone . Silt can occur as a deposit or as material transported by a Stream or by a Current in the Ocean . Silt is easily transported in Water and is fine enough to be carried long distances by air as ' Dust '. Thick deposits of silty material resulting from ''aeolian'' deposition are often called '' Loess '' (a German term) or ''limon'' (French). Silt and clay contribute to Turbidity in water. Silt, deposited by annual floods along the Nile River , created the rich and fertile soil that sustained the ancient Egyptian civilization. This silt was depended on for this purpose. A decrease in silt deposited by the Mississippi River throughout the 20th Century has contributed to the disappearance of protective Wetlands and Barrier Islands in the Delta region surrounding New Orleans . {Link without Title} Silt feels like flour. {Link without Title} TRIVIA On the Nickelodeon animated series Doug , the title character once learned about silt and was tasked with writing a report on it.
