Deposited soil is a type of sedimentary material that has been transported and deposited by water, wind, or ice. It is composed of small particles such as clay, SILT, sand, and gravel. SILT is a type of soil particle that is smaller than sand but larger than clay. It is usually composed of quartz, feldspar, and other minerals. SILT is often found in river beds, lakes, and oceans, and can be used to create fertile soil for farming.
