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 glaciers, eolian abrasion ( sandblasting by the wind) as well as water erosionErosion is the displacement of solids ( soil, mud, rock, and so forth) by the agents of wind, water, ice, or movement in response to gravity. Although the processes may be simultaneous, erosion is to be distinguished from weathering, which is the decompos of rocks on the bedThe bed of a stream or river or creek is the physical confine of the normal water flow. The lateral confines (channel margins) during all but flood stage are known as the stream banks . In fact, a flood occurs when a stream overflows its banks and partlys of rivers and streams. Silt is sometimes known as 'rock flour' or 'stone dust', especially when produced by glacial action.
Silt can occur as a deposit or as material transported by a streamThe primary meaning of stream is a body of water, confined within a bed and banks and having a detectable current. Stream is the umbrella term used in the scientific community for all flowing natural waters. For other meanings of the word stream see Strea or by a currentA current is a movement or flow of fluids, especially water in a river or the ocean. A current can be any continuous, directed movement of a fluid. In a river or stream, the water is influenced by gravity, and flows downhill to reduce its potential energy in the oceanOcean covers almost three quarters (71%) of the surface of the Earth. This global, interconnected body of salt water is divided by the continents and larger archipelagos into five oceans as follows: Arctic Ocean Atlantic Ocean Indian Ocean Pacific Ocean S. Silt is easily transported in waterDrinking water This article focuses on water as we experience it every day. The water (molecule) article describes water from a scientific and technical perspective. Water is an abundant substance on Earth. It exists in many forms, such as sea, rain, and and is fine enough to be carried long distances by air as ' dustDust is a general name for minute solid particles of diameters less than 500 micrometers (otherwise see sand or granulates) and, more generally, for finely divided matter. On Earth, dust occurs in the atmosphere from various sources: soil dust lifted up b'. Thick deposits of silty material resulting from aeolian deposition are often called loessLoess is a fine, silty, windblown ( eolian) type of unconsolidated deposit, or, sometimes the term refers to the soil derived from it. It is derived from glacial deposits, where glacial activity has ground rocks very fine ( rock flour). After drying, thes (a German term) or limon (French). Silt and clay contribute to turbidity in water.
Sedimentary rock composed mainly of silt is known as siltstone.
