What is the difference between precipitation and sedimentation?
Precipitation is the falling of water from the atmosphere, while sedimentation is the settling of particles from a fluid.
Precipitation is the accumulation of soil particles in a riverbed.
Sedimentation refers to the formation of clouds in the sky.
