What does it mean when particles fall out of suspension is sedimentation?
Understand the Problem
The question defines sedimentation as the process where particles fall out of suspension. This means if you have a mixture where solid particles are dispersed in a liquid or gas (a suspension), sedimentation is what happens when those particles settle to the bottom due to gravity.
Answer
Sedimentation is the settling of particles out of a fluid, usually due to gravity.
Sedimentation is the process where particles in a suspension settle out of the fluid they are in and come to rest against a barrier, typically due to gravity.

More Information
Sedimentation is used in water treatment to remove solid particles from water. It can also occur naturally, such as when soil erodes and is carried into a body of water where it settles.
Tips
A common mistake is thinking that sedimentation occurs because the particles dissolve. However, in sedimentation, the particles remain solid but separate from the liquid.
