Sedimentation causes layers of sand and silt to settle at the bottom of the river.

Definition

Noun: 1. The process of depositing or settling of solid material from a fluid: Sedimentation is the natural process where suspended particles in a liquid (or sometimes a gas) settle down and accumulate at the bottom due to gravity. 2. The resulting accumulation of such material: The word can also refer to the layer or mass of material that has settled.

Usage

Sedimentation is a key concept in geology, environmental science, chemistry, and water treatment. It describes a passive separation process. * In geology, it is a primary force in forming sedimentary rocks. * In water treatment, sedimentation tanks are used to remove particles from water. * In medicine, a sedimentation rate test measures how quickly red blood cells settle in a tube.

Examples
  • The sedimentation of silt at the river's delta creates new land over centuries.
  • The laboratory uses a centrifuge to accelerate the sedimentation of particles in the sample.
  • A high erythrocyte sedimentation rate can indicate inflammation in the body.
Advanced Usage
  • Sedimentation rate/velocity: The speed at which particles settle in a fluid, often used in scientific measurements.
  • Sedimentation tank/basin: A structure designed to allow solids to settle out of wastewater.
  • Gravitational sedimentation: Sedimentation caused solely by the force of gravity.
Variants and Related Words
  • Sediment (n): The solid material that settles, such as sand, silt, or mud.
    • Layers of sediment at the bottom of the lake.
  • Sedimentary (adj): Relating to or formed by sedimentation.
    • Sandstone is a common sedimentary rock.
  • Sedimentology (n): The branch of science that studies sedimentary rocks and processes.
Synonyms
  • Deposition
  • Settling
