sediment
의미: Solid material such as sand, silt, or clay that settles to the bottom of a liquid, especially material deposited by water, wind, or glaciers.
Sediment plays a vital role in geology, ecology, and water management. The accumulation of sediment over millions of years forms sedimentary rocks such as sandstone, limestone, and shale. River sediment creates fertile floodplains and deltas. In wine and coffee terminology, sediment refers to particles that settle at the bottom of a bottle or cup. The adjective 'sedimentary' and the process noun 'sedimentation' are common in scientific contexts.
