sedimentation
意味: The process by which particles of sand, silt, clay, or organic matter settle out of water or air and accumulate in layers, eventually forming sedimentary rock.
Sedimentation is a fundamental geological process responsible for creating sedimentary rocks such as sandstone, limestone, and shale. It also occurs in water treatment, where suspended particles are allowed to settle in tanks. 'Sedimentation rate,' 'sedimentation process,' 'sedimentation tank,' and 'sedimentary layers' are standard collocations. In medicine, the erythrocyte sedimentation rate (ESR) measures how quickly red blood cells settle in a test tube, serving as a marker of inflammation.
