Sedimentation - Wikipedia

Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.In geology, sedimentation is often used as the opposite of erosion, i.e., the ...
