Sediments are solid particles that are transported and deposited by water, wind, or ice. The term 'sediments' can refer to a variety of materials, including LEES (residue from fermentation), deposits (materials left behind after a liquid evaporates), silts (fine-grained soil particles), and DREGS (the sediment at the bottom of a liquid). Residua is another term for sediments, referring to the material that remains after a process has been completed.
