Silt is created when rock is eroded, or worn away, by water and ice. As flowing water transports tiny rock fragments, they scrape against the sides and bottoms of stream beds, chipping away more rock. The particles grind against each other, becoming smaller and smaller until they are silt-size.
How Is Silt Formed?
Silt is a type of sediment that is made up of small, fine particles of rock, minerals, and organic matter. It is usually found in rivers, lakes, and other bodies of water, as well as in soils.
Silt forms when rocks and minerals are broken down by processes such as weathering, erosion, and transportation. Weathering is the process by which rocks and minerals are broken down by physical, chemical, and biological processes.
Mechanical weathering occurs when rocks are broken down by physical forces such as wind, rain, and ice. Chemical weathering occurs when rocks are dissolved by acids or other chemicals.
Biological weathering occurs when living organisms break down rocks and minerals. All of these processes can cause rocks and minerals to break down into smaller and smaller particles, which eventually become silt.
Erosion is the process by which particles of rock and sediment are transported away from their source. It occurs when water, ice, wind, or gravity moves particles from one place to another.
